    BACKGROUND
    [001] In recent years, the ability to control crop input applications on a specific field basis (known as "precision farming") has increased interest in types of variable input across a field. In particular, advances in seed genetics and agronomic research have increased the need for solutions that allow for a variation of seed types in the field during the planting operation. Some proposed solutions involve switching between input types fed to the measurement units, which can result in a mix of input types in the measurement units and thus mixed input regions in the field. Preferred solutions would quickly transition between input types with limited mixing between seed types.
    [002] Thus there is a need in the art for systems, methods and apparatus to effectively select and vary the types of agricultural inputs during field operation. Brief Description of Drawings

    [0045] Referring now to the drawings, in which similar reference numerals designate identical or corresponding parts through different views, figure 1 illustrates a seed drill 10 having a structure 12 that includes a tool bar that extends transversely 14. One plurality of inline units 200 are mounted on the tool bar 14 in a transversely spaced relation. A plurality of hoppers of volume 110 is preferably supported by frame 14 and in seed and pneumatic communication with inline units 200.
    [0046] Now returning to figure 2, a modality is illustrated in which the line seeding unit 200 is the line seeding unit. The in-line seeding unit 200 is preferably connected in pivot mode to the tool bar 14 by a parallel connection 216. A drive element 218 is preferably arranged to apply a lifting and / or lowering force to the seeding unit in line 200. A solenoid valve (not shown) is preferably in fluid communication with the drive element 218 to modify the lift and / or lower force applied by the drive element. An opening system 234 preferably includes two opening discs 244 mounted in scroll mode to a downward extending rod 254 and arranged to open a V-shaped slot 38 in the ground 40. A pair of depth adjusting wheels 248 is pivotally supported by a pair of arm portions of regulating wheels of corresponding depth 260; the height of the depth regulator wheels 248 in relation to the opening discs 244 adjusts the depth of the slot 38. A depth adjustment rocker 268 limits the upward travel of the depth regulator wheel arm portions 260 and thus the upward travel the depth regulator wheels 248. A downward force sensor (not shown) is preferably configured to generate a signal related to the amount of force imposed by the depth regulator wheels 248 on the ground 40; in some embodiments the downward force sensor comprises an instrumented pin on which the rocker 268 is pivotally coupled to in-line seed units 200, such as the instrumented pins described in Applicant's US Patent Application No. 12 / 522,253 ( Pub. No. US 2010/0180695), the description of which is hereby incorporated by reference.
    [0047] Continuing with reference to figure 2, a first seed measurement element 300-1 such as that described in Applicant's copending international patent application No. PCT / US2012 / 030192 ("application 192"), the description of which is hereby incorporated by reference, is preferably mounted to in-line seeding units 200 and arranged to deposit the seeds 42 within the slit 38, for example, through a seed tube 232 arranged to guide the seeds towards the slit . In other embodiments, the seed tube 232 is replaced with a seed transport element such as that described in Applicant's copending international patent application No. PCT / US2012 / 057327 ("application 327"), incorporated herein by reference. A second seed measuring element 300-2 such as that described in order 192 is preferably mounted on in-line seed units 200 and arranged to deposit seeds 42 within the same slot 38, for example, through the same seed tube 232 In embodiments in which the seed tube is replaced with a seed transport element, the seed measurement elements 300-1, 300-2 provide seed within the same seed transport element; in embodiments in which the seed transport element includes a supply wheel for launching seed into the seed transport element, the seed transport element is preferably configured to alternatively launch seeds from the seed metering element 300 -1 and the seed measurement element 300-2 within the seed transport element.
    [0048] Continuing with reference to figure 2, each of the seed measuring elements 300-1, 300-2 preferably includes a side seed housing 330 having an auxiliary hopper 332 for storing seeds 42 to be deposited by the seed element measurement. Each of the seed measuring elements 300-1, 300-2 preferably includes a side vacuum housing 340 which includes a vacuum port 342 for pulling vacuum within the side vacuum housing. Each of the seed measuring elements 300-1, 300-2 preferably includes a seed disk 320 which includes a plurality of portions of seed openings 322 (see figure 6); the seed disk 320 preferably separates the inner volumes of the side vacuum housing 340 and the side seed housing 330. In operation, the seeds 42 communicate from the auxiliary hopper 332 within the side housing of only 330 are captured in the portions of seed openings 322 by virtue of the vacuum in the side vacuum housing and then released into the seed tube 232. Each measuring element is preferably driven by individual electrical actuating elements 315-1, 315-2 respectively. Each drive element 315 is preferably configured to drive a seed disk 320 within the associated seed measurement element 300. Each electrical drive element 315 preferably comprises an electrical drive element such as one of the embodiments described in International Patent Application No PCT / US2013 / 051971 and / or US Patent No. 7,617,785, the description of both of which is hereby incorporated herein in its entirety by reference. In other embodiments, the drive element 315 can be replaced with a hydraulic drive element or another motor configured to drive the seed disk.
    [0049] A modality of the seed measurement elements 300-1, 300-2 is illustrated in detail in figures 26-30. With reference to figures 29-30, the seed measuring elements 300-1,300- 2 are preferably joined together. The side seed housings 330-1, 330-2 preferably comprise a unitary part that includes an outlet channel 334 arranged to receive the seeds released by both seed measuring elements 300. The side seed housings are preferably arranged so that the seeds released from the seed disks in both measuring elements 300 (for example, at the 3 o'clock position) fall into the outlet channel 334. Although in normal operation, the seeds must simply fall freely from the 3 o'clock position of the seed disk within the outlet channel 224, a guide surface 339 is preferably arranged to prevent seeds deposited by the seed measuring element 300-2 from falling downward into the outlet channel if the seed measuring element seed 300-2 release the seeds before or after the 3 o'clock position. The outlet channel 334 is preferably mounted to an upper end of the seed tube 232 so that the outlet channel 334 communicates the seeds from both seed measuring elements 300 to the seed tube 232.
    [0050] Each of the side seed housings 330 preferably includes an opening portion 338 in communication with an auxiliary hopper 332. With reference to figures 27-28, a protective element 380 is preferably mounted to each seed measuring element 300 Each protection element 380 preferably includes a ventilation device 336 in fluid communication with an inner volume of the side seed housing 330. A screen (not shown) is preferably mounted to the ventilation device 336 to prevent small particles or residues enter the ventilation device 336. The protective element 380 is preferably arranged to protect the ventilation device 336 from rain. The protective element 380-2 preferably includes a mounting receptacle 382. The protective element 380-1 preferably includes a portion of mounting hook 384. Referring to Figure 26, in-line seed units 200 preferably includes a mounting bar 282 configured to pivot the mounting receptacle 382 in rotary mode. The line seeding units 294 preferably includes a latch configured to selectively engage the mounting hook portion 384. In an installation phase, the operator preferably hook the mounting receptacle 382 to the mounting bar 282 and rotate the measuring elements 300 downwards (clockwise in the view in figure 26) until the outlet channel 334 engages the seed tube 232. The operator then fixes the portion mounting hook 384 in line seeding units 200 using lock 294. Thus the mounting bar 282 and lock 292 cooperate to selectively retain the semiconductor measuring elements between 300 in engagement with the line seeding units 200 and in communication with the seed tube 232.
    [0051] A seed sensor element 150 (for example, an optical or electromagnetic seed sensor element configured to generate a signal indicating the passage of a seed) is preferably mounted to the seed tube 232 and arranged to send light or electromagnetic waves through the seed path 42. A closing system 236 that includes one or more closing wheels is pivotally coupled to in-line seed units 200 and configured to close slot 38.
    [0052] Returning to figure 3, a seed variety selection system 100 is illustrated. System 100 preferably includes a plurality of volume hoppers 110 (for example, two volume hoppers 110a and 110b as illustrated). The first volume hopper 110a preferably contains a first seed variety (for example, a first corn seed variety or a first soybean variety); the second hopper of volume 110b preferably contains a second variety of seed (for example, a second variety of corn seed or a second variety of soybeans). Each volume hopper is preferably in fluid communication with an individual seed entrainment agent 115. Each seed entrainment agent 115 is preferably mounted at a lower outlet of the associated volume hopper 110. Each seed entrainment agent 115 is preferably in fluid communication with a pneumatic pressure source P and configured to transport airborne seeds through a plurality of seed lines 120 to the inline units 200. By means of a plurality of seed lines 120a, the volume hopper 110a and entraining agent 115a are preferably in seed communication with a first seed measuring element 300-1 (for example, with auxiliary hopper 332-1) of each of the in-line seed units 200 along the bar of tool 14. In operation, the volume hopper 110a provides the first seed variety for the first measuring element 300-1 of each of the in-line seed units 200. By means of a plurality of seed lines 120b, the volume hopper 110b and entraining agent 115b are preferably in seed communication with the second seed measuring element 300-2 (for example , with auxiliary hopper 332-2) of each of the in-line seed units 200 along tool bar 14. In operation, the volume hopper 110b supplies the second seed variety to the second measuring element 300-2 of each of the 200 row seeding units.
    [0053] Continuing with reference to figure 3, each drive 315-1, 315-2 is preferably in data communication with a drive control device 160. The drive control device is preferably configured to generate a drive command signal drive that corresponds to a desired seed disc rotation coefficient. The drive control device 160 is preferably in data communication with a monitor of the sowing device 190. The monitor of the sowing device 190 preferably includes a memory, a processor, and a user interface. The sowing device monitor is preferably configured to send trigger command signals and / or desired seed disk rotation coefficients to the drive control device 160. The sowing device monitor 190 is preferably in data communication with a seed receiver. GPS 195 mounted either to the sowing device 10 or the tractor used to drag the sowing device. The monitor of the sowing device 190 is preferably in data communication with a speed sensor 197 (for example, a radar speed sensor) mounted either to the sowing device 10 or to the tractor. As used here, "data communication" can refer to anyone in electrical communication, electronic communication, wireless communication (for example, radio), or communication by any other means configured to transmit analog signals or digital signals.
    [0054] Returning to figure 33, a mode of entraining agent 115 is illustrated in detail. The air from the pressure source P enters an inlet portion 3310; the air in the inlet portion 3310 generally has a velocity vector I. Air from the inlet portion 3310 preferably enters the lower portion of the volume hopper 110 adjacent to a location where the amount of seed 3320 accumulates by gravity. The air entrains seeds within a 3330 outlet portion; the air in the outlet portion 3330 generally has a velocity vector O. The seed preferably passes from the outlet portion 3330 to one of the in-line units 200 via one of the seed lines 120. The entraining agent 115 preferably includes a bypass channel 3340 that extends between the input portion 3310 and the output portion 3330. The bypass channel 3340 is preferably arranged within the volume hopper 110. The bypass channel 3340 is preferably closed from the inside volume volume hopper 110 so that air flows through the bypass channel without obstruction by seeds. Bypass air that moves from inlet portion 3310 to outlet portion 3330 via bypass channel 3340 generally has a velocity vector B. In some embodiments, a valve (for example, a ball valve ) is arranged in the bypass channel 3340 so that the operator can vary an opening portion through which air is required to flow in order to pass through the bypass channel. In some embodiments, a plurality of bypass channels in the entraining agent each of which includes a valve; the plurality of valves is preferably controlled by a single hand-operated element (e.g., a lever) or in some embodiments by one or more electrically operated actuating elements.
    [0055] In some embodiments, a drive control device 160 associated with each of the line seeding units 200 is configured to receive signals from the monitor of the seeding device 190 via a bus (for example, a bus CAN) and to receive encoded signals from a motor from and send drive command signals to each of the drives 315-1, 315-2 (for example, via point-to-point electrical connections). In other embodiments, a separate drive control device 160 is associated with each drive 315.
    [0056] In still other modalities as illustrated in figure 21, a single drive element 315 is configured to alternately drive any of the seed disks 320-1, 320-2 by means of a clutch 317 configured to arrange an output shaft of the motor in operating connection with one or the other of the 320-1, 320-2 seed disks. The clutch is preferably configured to alternate the operating connection of the drive element 315 from a seed disk in response to a clutch command signal. As an illustrative example, clutch 317 can alternate an intermediate gear between a first position and a second position; in the first position the intermediate gear operationally connects the drive element 315 to the first seed disk 320-1 for the drive of the seed disk 320-1, and in the second position the intermediate gear operationally connects the drive element 315 to the second seed disk 320-2 for driving the seed disk 320-2. The drive control device 160 is preferably in data communication with the clutch 317 to send the clutch start signals to the clutch. The drive control device 160 is preferably configured to receive signals from the monitor of the sowing device 190 by means of a bus (for example, the can bus) and to receive encoded signals from a motor from and send control signals from drive for the single drive element 315 (for example, via point-to-point electrical connections).
    [0057] Continuing with reference to figure 3, each vacuum port 342 is preferably in fluid communication with a vacuum source 170 via a vacuum line 172. In some embodiments, the vacuum source 170 comprises a vacuum tube having outlet portions corresponding to vacuum ports 342. In order to reduce vacuum loss, at least some of the outlet portions are preferably arranged at an angle less than 90 degrees with respect to the vacuum tube; for example, angled 45 degrees in a forward direction. The outlet portions can additionally define a curvilinear flow pattern having an acute outlet portion angle at the interface between the vacuum tube and each outlet portion.
    [0058] With reference to figures 24-25C, in some embodiments the vacuum source 170 is in fluid communication with each pair of vacuum ports 342 through the solenoid-operated valve 175. In the solenoid-operated valve modality 175 illustrated in figures 25A-25C, the solenoid operated valve includes a vacuum inlet I portion in fluid communication with vacuum source 170, two vacuum outlet 0-1.0-2 portions in fluid communication with ports vacuum 342-1,342-2, respectively, and a deflection element 177 selectively movable between three positions in response to a control signal received from the monitor of the sowing device 190, which is preferably in data communication with the valve operated with solenoid. In the first position illustrated in figure 25 A, deflection element 177 partially blocks flow to the second vacuum port 342-2, establishing only the vacuum level in measuring element 300-2 necessary to retain the seeds in the seed disk 320-2 (for example, 10 inches of water), and leave the first outlet portion 0-1 substantially open. In the second position illustrated in figure 25B, deflection element 177 partially blocks flow to the first vacuum port 342-1, establishing only the vacuum level in measuring element 300-1 necessary to retain the seeds in the seed disk 320 -1 (for example, 10 inches of water), and leave the second outlet portion 0-2 substantially open. In the third position illustrated in Figure 25C, deflection member 177 preferably leaves both outlet portions 0-1, 0-2 substantially open. In operation, the sowing device monitor 190 preferably commands valve 175 to move to the first position when only the first measuring element 300-1 is planted (for example, when only the driving element 315-1 is commanded to drive ), commands valve 175 to move to the second position when only the first measuring element 300-2 is planted (for example, when only the driving element 315-2 is commanded to act), and commands valve 175 to move to the third position when both measuring elements 300 are planting (for example, when both drive elements 315 are commanded to drive).
    [0059] Continuing with reference to figure 3, not only the first seed measuring element 300-1 but also the second seed measuring element 300-2 of each of the row seeding units 200 are preferably in seed communication with (for example, arranged to deposit seed in) a seed tube 232 associated with the in-line seed units 200. The seed sensor element 150 associated with the seed tube 232 of each of the in-line seed units 200 is preferably in data communication with the monitor of the seed drill 190.
    [0060] In other modalities of the variety selection system 100, the third volume hopper is in fluid communication and in seed communication with the second seed measurement element 300-2 in all or in a subset of the in-line units 200. In the said modalities, the third volume hopper can be filled with seed waste. In yet other embodiments, the third volume hopper can be filled with another granular inlet such as a granular fertilizer. In some embodiments, the third volume hopper is in fluid communication and in seed communication with the third seed metering element in all or a subset of the inline units 200, the third seed metering element preferably arranged to deposit the seed within the same seed tube 232 as the first and second measuring elements 320-1,320-2.
    [0061] In some embodiments the third seed measuring element 320-3 is arranged above the second measuring element 320-2 as illustrated in figures 28A and 28B and preferably arranged to release seeds into the same seed tube 232, preferably to along the same transverse plane Pt, and preferably along the same longitudinal plane PL the third seed measurement element 320-3 preferably rotates in an R-3 direction equivalent to the R-1 direction. In the embodiment of figure 28A, an auxiliary seed tube 392 is arranged to guide the seeds from the third measuring element 320-3 towards the seed tube 232; as illustrated, the auxiliary seed tube is arranged below the seed release point of the third measuring element 320-3 and above the seed tube 232 and arranged vertically between the seed release point of the third seed measuring element 320 -3 and the seed release point of the seed measurement elements 320-1, 320-2. In the embodiment of figure 28B, the endless conveyor belt 394 is arranged to guide the seeds from the third measuring element 320-3 towards the seed tube 232; as illustrated, the endless conveyor belt is arranged to receive the released seeds from the third measuring element 320-2 which releases the seeds at a point vertically above the seed tube 232. A support wall 396 is preferably arranged to hold the seeds on the endless conveyor belt 395 during the vertical path before release.
    [0062] A modality of the line seeding units 200 is illustrated in figures 4-6. The seed disks 320-1, 320-2 (of the seed measuring elements 300-1, 300-2, respectively) are arranged in a lateral offset Dh from a central vertical plane P1 of the seed tube 232. The measuring elements 300 preferably release the seeds 42 at approximately the 3 o'clock position (along the seed disk view 320-1 in figure 6) of the seed disk, for example, by vacuum cutting as is known in the art. The central rotational axes of the seed measuring elements 320-1, 320-2 are preferably longitudinally displaced back and forth, respectively, from a transverse plane Pt that intersects an inlet portion of the seed tube 232 so that the seeds are released into the seed tube. As shown in figure 6, the seed disks 320-1, 320-2 preferably rotate in opposite directions R-1, R-2, respectively, in the operation of the seed measuring elements 300. The seed disks 320-1, 320-2 preferably release the seeds 42 along arcuate paths A-1, A-2 respectively, so that each seed travels laterally internally to the associated seed disk as the seed falls from the disk. It should be noted that said arcuate seed release can be effected by one or more characteristics of the seed disk; for example, the seed opening portions 322 are preferably chamfered so that the seeds are released over an angled surface. The displaced Dh is preferably selected so that the seeds 42 released from both seed disks 320 fall into the seed tube 232, preferably adjacent to the PI plane. The displaced Dh is preferably between .1 and .75 inches and is preferably about .5 inches. Because the seed tube 232 is preferably in substantial alignment with the slit 38, said release of seeds within the transverse center of the seed tube 232 ensures that the seed tube 232 deposits the seeds within the transverse center of the slit 38 formed by the line seeding units 200. Thus the seed measurement elements 300 mounted for the line seeding units 200 are configured and arranged to release the seeds within the transverse center of the gap 38 opened by the line seeding units 200 .
    [0063] The second modality of the line seeding units 200 'is illustrated in figures 7-9. In the second embodiment, seeds 42 are released from seed disks 320-1, 320-2 along substantially vertical paths V-1 and V-2, respectively. The seeds 42 enter the upper inlet portion of a modified seed tube 232 'in positions transversely spaced from the seed tube, for example, transversely spaced from the PL plane. The modified seed tube 232 'preferably includes a guide surface 234 configured to guide the seeds from their transversely spaced entry points in the upper inlet portion of the seed tube to the PI plane prior to release from the seed tube. The displaced lateral Dh of the seed disks 320 is preferably less in the second embodiment, for example, between 0 and .5 inches. In some embodiments, the longitudinal displacements of the central rotational axes of the seed disks 320 from the Pt plane are different so that the seeds are released from the disks 320-1, 320-2 backwards and forwards, respectively, from the plane Pt.

When the flow dividing element 1100 is installed in the seeding apparatus, each flow dividing portion 1130 preferably defines a vector of seed velocity and air Vs less than 70 degrees from vertical and preferably approximately vertical. Each flow dividing portion 1130 preferably sets the velocity vector Vs over the distance of the course Dv sufficient to allow the seeds to travel only for the moment (that is, not under the influence of airflow) to reduce from their speed of entry to a complete stop so that the seed does not travel to the exit portion 1140 without being influenced by the air flow. In preferred embodiments, the distance Dv is preferably greater than about 1.5 inches.

Modalities of seed units in row hopper of seed
    [0077] With reference to figures 15-17, in alternative modalities one or both of the seed measurement elements 300 in the line seeding units 200 are in seed communication with the seed hopper 1500 supported by the sowing device. Each seed measuring element is preferably in communication with a volume containing seed 1525; in operation, seed from the hopper 1500 preferably enters the side seed housing of the measuring element 300 after gravity travel down an inclined surface 1510. Referring to figure 17, an inclined surface 1512 preferably guides the seed by gravity in inclined surface direction 1510-1; for example, in the view of figure 17 the rightmost end of surface 1512-1 is preferably at a higher elevation than the leftmost end of surface 1512-1. Each volume containing 1525 seed is preferably approximately 1.6 bushels or larger. In the illustrated embodiment, a single seed hopper 1500 includes a single interior volume 1520 separated into two volumes containing seeds 1525-1, 1525-2 by a dividing element 1515; the interior volume 1520 is preferably approximately 3 bushels or greater. With reference to figure 16B, in a preferred embodiment the dividing element 1515 can be selectively tilted within an orientation in which the seed added to a hopper 1500 is only communicated to the seed measuring element 300-1; in said orientation, the volume containing seed 1525-1 is preferably greater than in the configuration of figure 16A. With reference to figures 16C to 16E, another embodiment of a dividing element 1515 'can be inserted into one of a plurality of vertical guide slots (not shown) in a hopper 1500 in order to selectively vary the ratio of seed types in the hopper . As illustrated, the divider element 1515 'preferably includes a vertical side wall portion and an angled portion that cooperates to define two uneven volumes in a seed hopper. In figure 16C, the dividing element 1515 'is in the first position in which the volume containing seed 1525-1 is greater than the volume containing seed 1525-2. In figure 16D, the dividing element 1515 'is in the second position in which the volume containing seed 1525-2 is greater than the volume containing seed 1525-1. In figure 16E, the dividing element is in the third position in which the vertical side wall divides the hopper 1500 so that the volume containing seeds 1525-1 and 1525-2 has substantially similar volumes. Seed hopper tool bar modes
    [0078] With reference to figure 20, in some embodiments a plurality of seed hopper is mounted to the tool bar 14 to supply seed to the measuring elements 300 in the inline units 200. In the illustrated embodiment, the seed hopper comprises hoppers seed 1500 described above, mounted to the tool bar 14 by means of a support element 1590. Each seed hopper is preferably in seed communication with two seed measurement elements 300 by means of seed lines 122, preferably in similar to the lines connecting the dividing elements 1100 described above with respect to figures 13 and 14. The seed hopper 1500 is preferably mounted in an elevated position with respect to the measuring elements 300 so that the seed descends through the tubes by gravity. In the illustrated embodiment, the first seed hopper 1500a provides a first type of seed to the seed measuring element 300-1 in the first row seeding units 200-1 and supplies the first type of seed to a seed measuring element 300 -1 in the second 200-2 row seeding units (not shown); thus in the illustrated embodiment, the divider element 1515 is preferably inserted in the hopper 1500a and the hopper is preferably filled with only a first type of seed. In the illustrated embodiment, the second seed hopper 1500b (not shown) is preferably mounted in a similar way to the tool bar and in seed communication with seed measuring elements 300-2 in the line seeding units 200-1 as well as to line seeding units 200-2 (not shown) to provide a second type of seed to the seed measuring elements 300-2 in line units 200-1, 200-2. In other embodiments, the hopper 1500 is in seed communication with the first seed measuring element 300-1 in the row seed units 200-1 as well as the second seed measuring element 300-2 in the row seed units 200-1; in said embodiments, a dividing element 1515 is preferably inserted in the hopper 1500 and the resulting two volumes containing seeds are filled with a first type of seed and a second type of seed, respectively. Trigger control methods
    [0079] Returning to figure 10, a process 1000 is illustrated to select a variety of seed planted by one of the modalities of the line seeding units 200 of the variety selection system 100. In step 1005, the monitor of the sowing device 190 preferably accesses the variety of seed maps, preferably stored in the monitor's memory of the seeding device. The seed variety map preferably comprises a file (for example, a format file) that associates the desired types of seeds with geo-referenced locations. In other embodiments, two separate format files can be used to independently control the measurement elements 300; in said modalities a first map file preferably instructs the first measurement element not to plant in places for which a second map file instructs a second measurement element to plant, and vice versa. In step 1010, the sowing device monitor 190 preferably identifies the nearest variety limit (i.e., the limit at which the currently desired seed variety is no longer desired and a different seed variety is desired) along the current path in-line seeding units 200. In step 1015, the seeder 190 monitor preferably obtains the speed of in-line seeding units 200 using one of the methods described in order 327. In step 1020, the seeder 190 monitor preferably estimates the time to the nearest range limit, for example, by dividing the distance to the range limit by the speed of the row seeding units. In step 1025, the sowing apparatus monitor 190 preferably compares the time estimated in step 1020 for a first predetermined delay and commands the first drive element 315-1 to stop when the time estimated in step 1020 is equal to a first predetermined delay. The first predetermined delay preferably corresponds to an empirically determined delay between the transmission of a command to stop the measuring element 300-1 and the last seed from the measuring element 300-1 being read by the seed sensor element 150. In step 1030, the sowing apparatus monitor 190 preferably compares the time estimated in step 1020 for a second predetermined delay and commands the second drive element 315-2 to start when the time estimated in step 1020 equals a second predetermined delay. A second predetermined delay preferably corresponds to an empirically determined delay between the transmission of a command to start the measuring element 300-2 and the first seed from the measuring element 300-2 being read by the seed sensor element 150. In other embodiments, instead of using a first and a second predetermined delay, the sowing apparatus monitor 30 preferably simultaneously commands a first drive element 300-1 to stop and a second drive element 300-2 to start when the estimated time in step 1020 it is equal to a change delay. In step 1035, the sowing device monitor preferably commands the speed for a second drive element 315 -2 based on an application coefficient map stored in the sowing device's monitor memory and associating the desired application coefficients with geographic locations. referenced.
    [0080] In other modalities of process 1000, the monitor of the sowing device 190 controls both measuring elements 300-1, 300-2 associated with the line seeding units 200 to plant in a mixed zone that defines a region between two seed variety map regions that request different seed varieties. In said modalities, the monitor of the sowing device 190 preferably commands both measurement elements to plant at half the associated coefficient by the application coefficient map with each location in the mixed zone. It should be noted that said modalities are beneficial when the first seed variety and the second seed variety comprise soya beans. In some of these modalities, the seed variety map does not include the mixed zone and system 100 implements the mixed zone at all locations within a predetermined distance (for example, 20 feet) from a variety limit.
    [0081] In some embodiments, the monitor of the sowing device 190 is configured to receive input from the operator to arrange the monitor of the sowing device in a "single input" mode in which both volume hoppers 110a, 110b are filled with the same type of seed. In the "single entry" mode, instead of performing process 1000, the monitor of the sowing device 190 commands the first seed measurement element to plant until a void signal is received. Once the void signal is received, the sowing apparatus monitor 190 preferably commands the first measuring element to stop and commands the second seed measuring element to plant. The void signal can comprise a signal from a sensor (for example, an optical sensor or a scale) configured to generate a signal that corresponds to the fill level of the volume hopper or the hoppers of the in-line seed units. The void signal can also comprise a signal from one or more seed sensor elements that indicate that no seed has been planted for a predetermined time or distance over which the first measurement element has been commanded to plant.
    [0082] In some modalities of process 1000, the monitor of the sowing apparatus 190 adjusts an angular position or speed of one or more of the seed disks 320 in order to achieve the desired alignment of the seed disks. It should be noted that these modalities can be useful when simultaneously planting with both seed disks 320 so that the seeds on the first seed disk 320-1 do not come into contact with the seeds on a second seed disk 320- two. In some desired alignments, the seed opening portions 322 are not transversely adjacent to each other. In said desired alignment, the angular positions of the seed disks 320 are shifted by half the angle between the portions of neighboring seed openings 322 in one of the seed disks. In some of the aforementioned embodiments, the monitor of the seed apparatus 190 adjusts the angular position or speed of a seed disk 320 based on a disk alignment signal in order to achieve the desired alignment. With reference to figure 19, the disk alignment signal may comprise a signal generated by Hall 1900 effect sensors arranged adjacent to the seed disk 320 and arranged to generate a pulse when a magnet 1910 mounted to the seed disk passes through the effect sensor Hall. In said embodiments, said Hall effect sensor is associated with both seed disks 320 in the seeding units in-line and the monitor of the seeding apparatus 190 preferably reduces or accelerates one of the seed disks 320 in order to achieve the desired time between the subsequent pulses in the signals received from not only the first Hall 1900-1 effect sensor but also a second Hall 1900-2 effect sensor. In other embodiments, the seed pulse signal from the seed sensor element 150 is used as a disk alignment signal; in said embodiments, the monitor of the sowing apparatus 190 preferably reduces or speeds up one of the seed disks 320 in order to achieve the desired time ratio (for example, 1 to 1) between subsequent seed pulses in the signal generated by the seed sensor element 150.
    [0083] Although the above description mainly describes systems, methods, and input selection apparatus with respect to seed planting, it should be noted that the same systems, methods, and apparatus can be used to vary between types of other granular agricultural inputs such as a granular fertilizer. Single-hybrid operating methods
    [0084] The seed variety selection system 100 is preferably capable of being reconfigured within a "single-hybrid" mode in which the system is configured to plant a single type of seed (for example, single hybrid) from both volume hoppers 110.
    [0085] Thus, with reference to figure 34, in some modalities the seed variety selection system 100 is configured to allow a 3400 reconfiguration process. In step 3405, the seed lines 120 that connect the first volume hopper 110-1 to the first subset of inline units 200 are preferably blocked for air flow. In a preferred embodiment, a first subset of in-line units comprises all in-line units on the right side of the seeder. In step 3410, the seed lines 120 connecting the second volume gear 110-2 to a second subset of inline units 200 are preferably blocked for air flow. In a preferred embodiment, a second subset of in-line units comprises all in-line units on the left side of the seeder.
    [0086] Each seed line 120 can be manually blocked by the operator using a removable plug on the seed line or on the pneumatic connection between the seed line and the seed measuring element or entraining agent in the outlet portion. Alternatively, each seed line can be manually closed using a valve or closed by means of a valve operated with electricity or a drive element in electrical communication with the monitor of the seed drill 190.
    [0087] In step 3415, the vacuum lines 172 connecting the vacuum source 170 to the measuring elements disconnected from the first volume hopper 110-1 in step 3405 (that is, in the first subset of in-line units) are preferably blocked for air flow. In step 3420, the vacuum lines 172 connecting the vacuum source 170 to the measuring elements disconnected from the second volume hopper 110-2 in step 3410 (that is, in the second subset of in-line seed units) they are preferably blocked for air flow.
    [0088] In some embodiments, instead of completely blocking the flow of vacuum to one of the measuring elements in each of the in-line seed units for operation in a simple hybrid mode, an orifice (not shown) is inserted into the vacuum line 172 connecting the vacuum source 170 to each measuring element disconnected from the first volume hopper 110-1 in order to partially block the air flow. In some embodiments, the orifice includes an opening portion sized to reduce the open area for the vacuum flow by about 70%. In some embodiments, the orifice includes an opening portion sized to reduce airflow by approximately 75%. The pressure in the vacuum source 170 in operation of said modalities can be approximately 20 inches of water in some implementations.
    [0089] Each vacuum line 172 can be manually blocked by the operator using a removable plug on a vacuum line or on the pneumatic connection between the vacuum line and the seed measuring element or the vacuum source. Alternatively, each vacuum line can be manually closed using a valve or closed by means of an electrically operated valve or actuating element in electrical communication with the monitor of the 190 similar apparatus. It should be noted that each vacuum line can be closed by a single valve or drive element arranged to shut off air flow to each vacuum line.
    [0090] In other modalities, system 100 is configured to allow operation in a simple hybrid mode in which the system alternately plants from the first volume hopper 110-1 and the second volume hopper 110-2. In said modalities system 100 the volume hopper currently "active" (that is, the volume hopper being planted from the current time) preferably distributes the seeds to a measuring element in each of the units in line; after the alternation of the volume hopper is executed the next currently active "hopper" preferably distributes the seeds to another measuring element in all units in line. Thus, with reference to figure 35, in said modalities the system 100 is preferably configured to perform the process of alternating the volume hopper 3500.
    [0091] In step 3505, system 100 preferably distributes the seed from the first hopper of volume 110-1 to one of the seed measuring elements (e.g., seed measuring element 300-1) in each of the units in-line seed drill 200 on the seed drill. In step 3510, system 100 preferably identifies the alternating criterion of the first volume hopper. With the identification of the alternation criterion of the first volume hopper, in step 3515 the system 100 preferably "alternates" to distribute seed from the second volume hopper 110-2 to the other seed measuring element (for example measuring element 300-2) in each of the in-line seeding units 200 in the sowing device (for example, by stopping the seed measurement of the first measuring element 300-1 and controlling the second measuring element 300-2 to measure the seed).
    [0092] The alternating criterion of the volume hopper of step 3510 can comprise any of the following: the seeder device being in a high configuration (for example, determined by an elevation toggle signal or elevation command); a predetermined number of passes executed (for example, determined by the change of direction reported by the GPS receiver, an elevation toggle signal or elevation command); a number of seeds dispensed (for example, as counted by a seed sensor element or estimated based on a speed measurement element); the distance covered (for example, based on radar or GPS coordinates); or an elapsed time. In preferred embodiments, a criterion for alternating the volume hopper is achieved at regular and relatively close intervals (for example, after each pass) so that the volume hoppers have an approximately equal weight during planting operations. In other embodiments, a criterion for alternating the volume hopper comprises an elapsed time without seed being read by one (or a plurality or all) of the seed sensing elements, so that a criterion for alternating the volume hopper is achieved only when the active volume hopper has been substantially emptied.
    [0093] In step 3520, system 100 preferably identifies a second alternating criterion for the volume hopper. With the identification of the second alternating criterion of the volume hopper, in step 3525 the system 100 preferably "alternates" to distribute the seeds from the first volume hopper 110-1 to another seed measuring element (for example measuring element 300-1) in each of the in-line seed units 200 in the seed drill (for example, by stopping the seed measurement of a first measuring element 300-2 and controlling a second measuring element 300-1 for the seed measuring element).
    [0094] A criterion for alternating the volume hopper of step 3520 can comprise any of said criteria recited with respect to step 3510 and preferably comprises the same criteria used in step 3510.
    [0095] It should be noted that the methods and apparatus for blocking the air flow in unused vacuum lines and seed lines described above with respect to the 3400 reconfiguration process can be implemented with each alternation of the volume hopper in the process of alternation of the 3500 volume hopper.

Various modifications to the preferred modes of the apparatus, and the general principles and characteristics of the systems and methods described here will be readily apparent to those skilled in the art.
