    FIELD OF THE INVENTION
    [001] The invention refers, in general, to planters or sowing and, in particular, to planters and sowing to plant multiple types or varieties of seed. BACKGROUND OF THE INVENTION
    [002] Modern farming practices seek to increase agricultural field yields. Technological advances in planters allow for better agronomic characteristics at the time of planting, such as providing more accurate seed depth, improved seed depth uniformity across the planter and improved in-line seed spacing accuracy. However, a single field may have inconsistencies in production performance between different areas of the field. This is due to the fact that a field can have a wide variety of soil types and management types or zones, such as irrigated and non-irrigated zones in different areas. Seed companies are developing multiple varieties of each of their types of seed products to improve production in these different areas. Different seed varieties offer improved performance characteristics for different types of soil and management practices. Efforts have been made to plant multiple varieties of a particular type of seed product in different areas of fields with different types of soil or management zones. These efforts include planters that have different volume fill hoppers and require that the reservoir for each seed feeder be completely cleaned or transplanted before a different seed variety can be delivered to the seed feeders. Some planters allow you to plant two varieties and include auxiliary line units or two separate and separate seed dosers in each of the line units. BRIEF DESCRIPTION OF THE INVENTION
    [003] The present invention is directed to systems for in-line planting that allow planting multiple types of seed that may include planting at varying rates in a single planting pass. The system can allow alternation, during the course of the operation, of type (s) of seed that are planted from a single seed doser in each line unit of the planter. This can be achieved by an in-line hopper with multiple compartments that store multiple types of seed in each line unit and a selector set in each line unit that is controlled to selectively release one of the seed types from the in-line hopper in the seed doser based on an area of the agricultural field that is planted. When the planter approaches a limit between the first and second zones of the field, a selector valve (s) in the selector assembly acts to interrupt the delivery of a first type of seed from the hopper to the seed doser and begin delivering a second type of seed from the hopper to the seed dispenser. This allows you to plant multiple types of seed with a single seed feeder in each row unit, in a single planting pass, without having to add additional row units or seed feeders.
    [004] According to one aspect of the invention, the actuation of the selector valve (s) is synchronized in relation to the movement of the planter to allow the seeds of the second type of seed to be released from the planter when the planter crosses the limit from the first to the second zone. In one embodiment, the interruption and beginning of the release of the first and second types of seed is done substantially simultaneously, allowing for a transitional mixed seed planting phase, during which a mixture of the first and second seeds can be released from the planter. In another embodiment, the release of seeds of the first type of seed is interrupted and the release of seeds of the second type of seed is delayed until substantially all of the first type of seed has been released from the planter, allowing for a substantially distinct alternation of planting. first type of seed for planting the second type of seed, minimizing the mixture.
    [005] According to another aspect of the invention, a planter is provided to plant multiple types of seed, in a single planting pass, during in-line planting of an agricultural field. The planter includes a frame and multiple in-line units supported by the frame. Each of the multiple in-line units includes a multi-compartment in-line storage system with configuration to store multiple types of seed. Each line unit has a seed dispenser to plant multiple types of seed. Each seed dispenser includes a housing that defines a seed chamber in it to receive seeds for individual delivery and singling out from the seed dispenser. The seed feeder housing has an entrance that defines a passage from the outside of the seed feeder to the seed chamber. Each line unit has a selector assembly arranged between the multiple compartments of the in-line storage system and the entrance to the seed feeder housing. The selector set selectively releases the seeds of one of the multiple seed types from one of the corresponding multiple compartments of the online storage system, in the seed chamber of the seed dispenser at any given time.
    [006] In accordance with another aspect of the invention, the multiple compartments of the online storage system include compartment outlets, and the selector assembly includes an input segment arranged to receive seeds from the compartment outlets. The selector assembly can include at least one actuating selector valve to selectively block seed flows through one of the compartment outlets and allow seed flow through one of the compartment outlets to switch which of the multiple seed types is delivered to the chamber seed from the seed feeder. The selector set may include a valve system that selectively blocks flow and allows the flow of seeds of multiple types through the selector set to allow delivery of seeds of a single type among the multiple types outside the selector set at any given time. The selector assembly may include at least one selector valve configured to unblock and allow seed flow through a single outlet among the multiple compartment outlets of the inline storage system, and to block and prevent seed flow through the outlet outlets. remaining compartment of the in-line storage system, while the selector assembly is directing the seeds from the in-line storage system to the entrance of the seed dispenser housing.
    [007] According to another aspect of the invention, the selector valve is a linear actuated door or a door activated in a rotating manner that can be actuated electronically, hydraulically, pneumatically, through friction. The at least one selector valve may include a selector valve arranged in relation to each of the outlets of the in-line compartments. The at least one selector valve can be arranged closer to the outlets of the in-line storage system than the inlet to the seed dispenser housing. The selector assembly may include an outlet segment disposed between the inlet segment of the selector assembly and the entrance of the seed doser housing to direct the seeds of the selector assembly to the entrance of the seed doser housing. The outlet segment of the selector assembly may include an outlet duct that interconnects the selector assembly with the inlet of the seed feeder housing and that defines a passage that extends in a longitudinal direction, in relation to the outlet segment of the selector assembly , to direct the seeds of the selector set to the entrance of the seed doser housing.
    [008] According to another aspect of the invention, the multiple compartments are defined in a hopper and the compartment exits are defined in the bottom wall of the hopper. The input segment of the selector assembly is connected to the bottom wall of the hopper to receive seeds from the compartment outlets on the bottom wall. The multiple compartments are defined in a bulk storage hopper supported by the line unit, which can be filled manually or not pneumatically, so that the entire volume (s) of the seeds to be planted is (are) stored ( s) in the bulk storage hopper. The seeds stored in the bulk storage hopper are fed by gravity, from the multiple compartments at the entrance to the seed feeder housing. At least some of the multiple compartments are defined in a mini-shaker supported by the line unit and configured to pneumatically receive the seeds of the multiple types from a planter's bulk storage system, such as a filler hopper (s). centrally located volume (s).
    [009] According to another aspect of the invention, the planter has a frame and multiple line units supported by the frame. Each of the multiple row units has multiple compartments that store multiple corresponding seed types. Each line unit has a seed feeder to plant multiple seed types separately in separate areas of an agricultural field, where each zone corresponds to a characteristic of the agricultural field that refers to at least one of the soil types. and the type of management. A selector set extends between the multiple compartments and the seed dispenser to selectively release a first type of seed from among the multiple seed types, from a first compartment within one of the corresponding multiple compartments in the seed dispenser, to release in one first area of the agricultural field. The selector set selectively releases a second type of seed among the multiple types of seed from a second compartment among the multiple compartments in the seed dispenser to release in a second zone of the agricultural field.
    [010] According to another aspect of the invention, the multiple compartments include a volume receiving compartment, which pneumatically receives the first type of seed from a remote bulk storage system for bulk storage of the first type of seed and location which is removed from the line unit, and a bulk storage compartment for bulk storage of the second type of seed in the line unit. Each storage and volume receiving compartment has an output in fluid seed communication with an input segment of the selector assembly. This may include at least one actuating selector valve to selectively block the flow of seeds through the outlets of the storage and volume receiving compartments and which allows the flow of seeds through the outlets of the storage and volume receiving compartments to switch which of the first and second types of seed is delivered to the seed dispenser. The seed feeder includes an inlet that provides a passage for the seeds to flow into the seed feeder and the selector assembly includes an outlet duct arranged between at least one selector valve and the seed feeder inlet. The outlet duct of the selector assembly receives seeds of the first or second type allowed to flow through at least one selector valve and directs the seeds of the first or second type allowed to flow through at least one selector valve of the at least one a selector valve to the entrance of the seed doser.
    [011] According to another aspect of the invention, the planter includes a frame that supports multiple line units, and multiple compartments are arranged in each of the multiple units in line and configured to store the multiple types of seed. A seed feeder in each of the multiple line units is configured to plant multiple types of seed. Each seed dispenser includes a housing that defines a seed chamber in it to receive seeds for individual delivery and singling out from the seed dispenser. The seed dispenser housing has an inlet that defines a passageway for directing seed into the seed chamber. Each line unit has a selector assembly disposed between the multiple compartments and the entrance of the seed doser housing to selectively release seeds of one of the multiple types of seed, from one of the corresponding multiple compartments of the in-line storage system in the chamber seed from the seed feeder at a given time. A control system is operably connected to each selector set and configured to control which type of seed among the multiple types of seed is released in an agricultural field, based on the planter's location, in relation to the multiple zones of an agricultural field. Each of the multiple zones corresponds to a characteristic of the agricultural field that refers to at least one among the type of soil and the type of management. The control system controls the action of the selector set for alternating delivery of seeds of the first type from a first compartment of the multiple compartments through the selector set and in the seed chamber of the seed doser, when the planter is in a first zone between the multiple zones for the delivery of seeds of a second type from a second compartment of the multiple compartments through the selector assembly and in the seed chamber of the seed doser, when the planter is in a second zone among the multiple zones. The alternation event can be synchronized to occur when the planter crosses a boundary between the first and the second zone.
    [012] Other aspects, objectives, resources and advantages of the invention will become evident to people skilled in the art, from the detailed description and attached drawings below. It should be understood, however, that the detailed description and the specific examples, while indicating the preferred embodiments of the present invention, are given by way of illustration and not by way of limitation. Many changes and modifications can be made within the scope of the present invention, without departing from the spirit of the same, and the invention includes all such modifications. BRIEF DESCRIPTION OF THE DRAWINGS
    [013] Preferred exemplary embodiments of the invention are illustrated in the accompanying drawings, where similar reference numbers represent similar parts in their entirety. Figure 1 is a simplified schematic representation of a planting system for planting multiple varieties of seed. Figure 2 is a simplified schematic representation of a variant of the system in Figure 1; Figure 3 is a simplified schematic representation of another variant of the system in Figure 1; Figure 4 is a side elevation view of a simplified schematic representation of the system of Figure 2; Figure 5 is a side elevation view of a simplified schematic representation of the system of Figure 3; Figure 6 is a pictorial view of a selector assembly in Figure 4; and Figure 7 is a prescription map of the seed variety for use with the planting system in Figure 1. DETAILED DESCRIPTION OF THE ACCOMPLISHMENTS OF THE INVENTION
    [014] Referring now to the drawings and, specifically, to the simplified schematic representations of Figures 1 to 3, a system 5 is shown, which allows the alternation in movement of type (s) of seeds to be planted by a planter, without requiring manual cleaning of seed feeders or auxiliary line units or seed feeders. System 5 includes a planter 7, such as one of the planters in the EARLY RISER® series available from Case IH, pulled behind a traction device, such as a tractor 9. Planter 7 includes a frame 11 that supports multiple line units 13 that are substantially identical. As shown in Figure 5, each of the line units 13 has ground penetration tools that can include opening and closing mechanisms 15, 17, such as opening discs and closing discs, respectively, or other ground penetrating tools for open and close a groove. Grounding tools can also include a measuring wheel configured to adjust the groove depth by limiting the ground penetration of the groove opening mechanism of the grounding tools while creating a groove, and a press wheel it can be arranged to roll through the closed furrow to firm the soil on the seed to further close the furrow and promote favorable contact of the soil with the seed.
    [015] Referring again to Figures 1 to 3, planter 7 has a seed storage system 19 for separately storing seeds 21 of different types for planting in different areas or areas of a field. The seeds 21 may be of a common plant type, but of different varieties or types 21a, 21b, 21c, 21d. Although seed 21 can be described anywhere in this document, as the different types 21a, 21b, 21c, 21d, it should be understood that the description of the different types includes different varieties, in other words, the different types 21a, 21b, 21c, 21d of seed 21 include not only different varieties of the same plant species, but also different seed products. Different seed products can include seeds of different species, coated and uncoated seeds, such as insecticide-coated and insecticide-coated seeds. Products from different seeds may also include protection in a sack seed and non-protection in a sack seed, plant parasite-resistant seed and non-plant parasite-resistant seed, such as cyst-resistant nematode seeds and non-resistant seeds cyst nematodes, herbicide-tolerant seeds and non-herbicide-tolerant seeds, or other different products. Different seed products may additionally include different planting seeds, such as corn and soybeans. Regardless, planter 7 is configured to plant the different types 21a, 21b, 21c, 21d of seed 21 in different variety or type zones, shown as zones VZ1, VZ2, VZ3, VZ4 on the PM prescription map of Figure 7. The zones of variety or of different types VZ1, VZ2, VZ3, VZ4 of the agricultural field are defined, at least in part, by characteristics related to at least one among the type of soil and the type of management.
    [016] Referring again to Figures 1 to 3, the seed storage system 19 includes a bulk storage system 23 and defines bulk filling compartments shown as bulk storage compartments 25 that store the types of seeds 21a, 21b, 21c, 21d in bulk for selective delivery to seed feeders 27, in line units 13, by means of a selector set 29 in each line unit 13, as explained in greater detail, anywhere in the present document. The seed storage system 19 also includes an in-line storage system 31 for storing seed types 21a, 21b, 21c, 21d in each of the row units 13. This arrangement allows for the selective release of one of the seed types 21a, 21b, 21c, 21d quickly switching which of the types of seeds 21a, 21b, 21c, 21d are released from selector sets 29 in seed dosers 27, in line units 13, to plant in zones VZ1, VZ2, VZ3, VZ4 (Figure 7), as it is controlled by a control system 33. The control system 33 includes a planter controller 35 and a tractor controller 37 that communicate operatively with each other, for example, by through an ISOBUS connection, to coordinate planter controls 9, such as seed dosers 27 and selector sets 29 and tractor 9 (Figure 1), based on the variety or type zones VZ1, VZ2, VZ3, VZ4 of the agricultural field, which can correspond to a ma prescription range or PM seed type as shown in Figure 7. The planter controller 35 is shown, including a controller 39 and a power supply 41. The controller 39 of the planter controller 35 can include an industrial computer or, for example, a programmable logic controller (PLC), together with the corresponding software and the appropriate memory to store such software and hardware, including interconnect conductors for signal and power transmission to control hydraulic, electromechanical and electronic components of seed dosers 27, selector sets 29 and other planter components 7. The tractor controller 37 is configured to control the operations of the tractor 9, such as controlling the driving, speed, braking, transmission and other operations of the tractor 9 The tractor controller 37 is shown to include a controller 43 and a power supply 45. The tractor controller 37 is configured to to control the functions of the tractor 9 by controlling the various driving systems by GPS, transmission, engine, hydraulics and / or other systems of the tractor 9. As controller 39 of the planter controller 35, controller 43 of the controller Tractor 37 can include an industrial computer or, for example, a programmable logic controller, along with corresponding software and adequate memory to store such software and hardware, including interconnect conductors for signal and power transmission to control hydraulic components , electromechanical and electronics of the tractor 9. A tractor interface system 47 is operably connected to the tractor controller 37 and includes a monitor and various input devices to allow an operator to view the status and control various operations of the tractor 9 from from inside the tractor cab 9. The tractor interface system 47 can be an Armrest® MultiControl console available for use with tractors s from the Maxxum® or Magnum® series, from Case IH.
    [017] Referring now to Figure 1, in this embodiment, the bulk storage system 23 is defined entirely in the online storage system 31, so that the entire volumes of all of the seed types 21a, 21b , 21c, 21d are stored in line units 13, with all bulk storage compartments 25 arranged within the online storage system 31. Bulk storage compartments 25, in this embodiment, are in a volume filling hopper shown as a single hopper in a volume 49 line, separated from each other by dividing walls or partitions 51 in each line unit 13.
    [018] While compartments 25 are defined in a single hopper in a volume line 49 in each line unit 13 in Figure 1, referring now to Figures 2 and 4, in this embodiment, the bulk storage system 23 is defined entirely in a volume filling hopper (s) shown as centrally located volume filling hoppers 49, with none of the bulk storage compartments 25 disposed within the online storage system 31. Rather, in this In this embodiment, the online storage system 31 has only bulk receiving compartments 53 that pneumatically receive seed types 21a, 21b, 21c, 21d, from the bulk storage compartments 25 of the centrally located volume filling hoppers 49. The bulk receiving compartments 53, in this embodiment, are separated from each other by partition walls or partitions 55 in a single hopper in a segmented line, shown as minitremon 57 in each line unit 13. The pneumatic delivery of seed types 21a, 21b, 21c, 21d, from bulk storage compartments 25, from centrally located volume filling hoppers 23 to the receiving compartments of bulk 53 of the online storage system 31 is made by means of an airflow system 59 and a cooperative primary delivery system 61. The airflow system 59 provides pneumatic power for use by various planter components 7, which include seed feeders 27, as well as seed transportation 21, from bulk storage system 23 to inline storage system 31. Airflow system 59 includes a positive air pressure source and may include a vacuum source to establish vacuum and positive pressures and corresponding air flows. The positive air pressure source and vacuum sources can be known pumps, fans, fans and / or other known air flow system components. As shown in Figures 4 and 5, in embodiments where the airflow system 59 provides pneumatic energy both for transporting seeds 21 from the bulk storage system 23 to the inline storage system 31 and for operation of the seed dispenser 27 , the air flow system 59 includes a seed transport air flow system 59a and a seed feeder air flow system 59b. The seed transport airflow system 59a provides an airflow that entrains the seeds 21 to move the bulk storage system 23 to the inline storage system 31. The seed feeder airflow system 59b provides positive and / or native pressure for the operation of seed metering units in line 13. The primary delivery system 61 releases or delivers seeds 21, as per calibrated measurement, from bulk storage in volume fill hoppers. centrally located 57 in a seed delivery system for transport to bulk receiving compartments 53 in mini-shavings 57. Primary delivery system 61 delivers seeds to be entrained in an air stream (s) through primary lines or seed ducts primary 63 that connect to secondary lines or secondary seed ducts 65 that extend to line units 13. Referring now to Figure 4, within the primary delivery 61, each bulk storage compartment 25 has its seed contents 21 measured by a measuring cylinder (s) 67 which can be a calibrated corrugated cylinder arranged at each outlet 69 of each bulk storage compartment 25, or the volume filling hopper (s) itself. Cylinders 67 are driven to rotate by electronic, pneumatic or hydraulic motors (not shown), as they are controlled by the control system 33, explained in greater detail anywhere in this document.
    [019] Referring now to Figures 3 and 5, in this embodiment, three types of seeds 21, such as seed types 21a, 21b, 21c, are shown with planter 7. The bulk storage system 23 is defined both within the online storage system 31 and in locations away from the online storage system 31. Bulk storage compartments 25 are provided in centrally located volume filling hoppers 49 and also within combined online hoppers 71. The combined in-line hoppers 71 have both bulk in-line storage and mini-shaker portions with bulk storage compartments 25 and bulk receiving compartments 53, respectively. A primary type of seed that will be planted with the highest volume in the field, shown as seed type 21a, is stored in bulk storage compartment (s) 25, which defines the primary bulk storage compartments 25 of centrally located volume filling hoppers 49 from a primary bulk storage system for pneumatic transport to the volume receiving compartment 53 in the mini hopper portion of the combined row hopper 71. The secondary types of seed that will be planted with relatively lower volumes in the field, shown as seed types 21b, 21c, are stored in the inline bulk storage compartment (s) 25, which define the secondary bulk storage compartments 25 of a secondary bulk storage system in the portion of online bulk storage of the combined in-line hopper 71.
    [020] Referring again to Figures 1 to 3, regardless of where seed types 21a, 21b, 21c, 21d are stored in bulk on planter 7, seed types 21a, 21b, 21c, 21d in the online storage system 31 are selectively released by the selector assembly 29 in each line unit 13 to the corresponding seed feeder 27. Each seed feeder 27 can be a purely mechanical seed feeder 27, a seed feeder electric 27 or a pneumatic seed dispenser 27. Referring now to Figures 4 and 5, the seed dispenser 27 has a housing 73 that can be a multi-component housing, with interconnected cover segments enclosing an interior cavity, in that an internal seed disk is rotated by a seed disk drive system. The seed disk drive system rotates at least one surface of the seed disk through a seed cluster of the collected seeds 21 in a seed chamber 75, within the inner cavity of the seed doser 27. Referring now to to Figure 4, the seed chamber 75 receives seeds from an inlet 77 of the seed doser housing 73 which defines a passage from outside the seed doser 27 to the seed chamber 75. Referring, again, in Figures 4 and 5, the rotation of the seed disk in the inner cavity inside the seed doser 27 allows the seed disk to collect and singularize the seeds from the internal group of seeds and transport the individual seeds through of the seed feeder 27 for individual release of the seed feeder 27 through a seed tube 79. The pneumatic seed feeders 27 are additionally operably connected to the airflow system 59 for provide a vacuum chamber within the seed doser 27, opposite the seed chamber 75 which allows the seeds of the seed cluster to be held against the seed disk by vacuum pressure to move the seeds 21 through the seed doser 27 to singularization in the seed doser 27 and delivery through the seed tube 79 in the field.
    [021] Without taking into account the particular configuration of the seed doser 27, the selector assembly 29 defines a conduit arrangement that directs the seed flow that selectively guides the types of seeds 21a, 21b, 21c, 21d, for example, a at a time or as a mixture, from the online storage system 31 to the seed doser 27. The selector assembly 29 is configured to selectively block the flow and allow the flow of seeds 21 of the multiple seed type (s) ) 21a, 21b, 21c, 21d, through the selector assembly 29, to allow the delivery of seeds of a single among the seed type (s) of the multiple types 21a, 21b, 21c, 21d outside the selector set, at a given time, as controlled by control system 33. Referring now to Figure 4, selector set 29 receives seed types 21a, 21b, 21c, 21d from outlets in compartment 81 that include openings that extend through a lower wall 83 of each of the s inline hoppers 49 (Figure 1), 57 (Figure 2), 71 (Figure 3). Referring now to Figures 4 and 5, the selector assembly 29 has a body with an input segment 85 and an output segment 87 that collectively extends between the inline hoppers 49 (Figure 1), 57 (Figure 2 ), 71 (Figure 3) and the respective seed feeder 27 and a valve system 89 to selectively guide the seed type (s) 21a, 21b, 21c, 21d, through the selector assembly 29, to the feeder of seed 27.
    [022] Referring now to Figure 6, the inlet segment 85 has an inlet body 91 with interconnected walls 93 collectively that define a tube to guide the seed type (s) 21a, 21b, 21c, 21d in a longitudinal direction, from the in-line hopper (s) 49, 57, 71 (Figures 1 to 3), towards the exit segment 87 of the selector assembly 29. The exit segment 87 has an outlet body 95 with interconnected walls 97 collectively that define an outlet duct 99 that can provide a tube to guide the seed type (s) 21a, 21b, 21c, 21d in a longitudinal direction , from the inlet segment 85 of the selector assembly 29, towards the seed metering inlet 77 (Figure 4). In this way, a passage 101 is defined longitudinally through the selector assembly 29, through the arrangement of the inlet and outlet segments 85, 87. The flow of the seed type (s) 21a, 21b, 21c, 21d, through passage 101, is (are) selectively allowed (s) and / or prevented (s) by valve system 89. As shown in this embodiment, valve system 89 can be arranged in inlet segment 85 of the selector assembly 29 or it may be adjacent, connected, or integrally embedded in the lower wall 83 of the in-line hopper (s) 49, 57, 71 (Figures 1 to 3).
    [023] Referring further to Figure 6, the selector assembly 29 includes at least one selector valve 103, shown here with four selector valves 103, which are operable to selectively block and / or allow the flow of seeds 21 through compartment outlets 81 (Figure 4) to switch which of the multiple seed types 21a, 21b, 21c, 21d are delivered to the seed chamber 75 of the seed doser 27 at any given time. Referring now to Figure 4, the selector valve (s) 103 can be arranged closer to the outlets 81 of the online storage system 31 than to inlet 77 of the metering housing seed 73, whereby the alternation of which types of seeds 21a, 21b, 21 s, 21d are released to be fed to the seed doser 27 is made upstream and away from the seed dosing inlet 77. Referring, again, to the Figure 6, an actuator 105 is arranged to move through each of the selector valves 103 to provide selective flow control of the corresponding seed type 21a, 21b, 21c, 21d to selectively feed the seed doser 27. The selector valves 103 and actuators 105 can provide an arrangement where selector valves 103 are linear actuated ports, such as those shown toward the top of valve system 89 of Figure 6. Or, selector valves 103 and actuators 105 can provide an arrangement where the selector valves s are a type of pivoted hinge or swing-operated doors, such as those shown towards the bottom of valve system 89 of Figure 6, as represented by selector valve 103 shown in a dashed outline that corresponds to an opening position in that the dashed outline selector valve 103 extends upwards, at an angle, to a top wall of selector assembly 29. Without taking into account the particular movement paths of selector valves 103, actuators 105 can be any among a variety of electronic, electromechanical, pneumatic and hydraulic actuators, which allow actuators 105 to be actuated electronically, hydraulically, pneumatically, through friction, to allow seeds 21 to be selectively released by type 21a, 21b, 21c, 21d, from the online storage system 31 to the seed dispenser 27.
    [024] Referring again to Figures 1 to 3, the online storage system 31 can store all seed 21 in bulk storage online, as shown in Figure 1, can receive all seed 21 from central bulk storage or remote, as shown in Figure 2, or it can either store seed 21 in bulk online or receive seed 21 from central or remote bulk storage, as shown in Figure 3. Referring again to Figures 2 and 4 , for designs with multiple bulk receiver compartments 53 that pneumatically receive seed types 21a, 21b, 21c, 21d, from bulk storage compartments 25 of centrally located volume filling hoppers 33, a seed gate system 107 is configured to maintain seed fill levels 21 in the bulk receiving compartments 53 and to ensure that each volume 53 receiving compartment has enough of its types regarding Seed assets 21a, 21b, 21c, 21d to allow the selector assembly 29 to release seed types 21a, 21b, 21c, 21d in the seed feeder 27, as controlled by control system 33. The door system seed 107 includes a seed port 109 at each junction, from which a volume receiving compartment 111 feed tube branches from its respective secondary seed conduit 65. Each seed port 109 is moved independently by a actuator 113 which can be electronic, pneumatic or hydraulic actuators to direct the seed 21 into a tube (s) within the feed tube (s) of the volume receiving compartment 111 to fill the bulk receiving compartments 53 of the mini-semester in segmented line 57. This is done by acting on the seed door 109 between an open position and a closed position to allow the flow and block the flow to the respective volume receiving compartment 53. The level sensors seed 115 are arranged in bulk receiving compartments 53 to provide signals that allow the control system 33 to assess how much seed 21 of the seed types 21a, 21b, 21c, 21d is in each of the recipient compartments volume (s) 53, in each of the line units 13. In this way, the control system 33 can use signals from the seed level sensors 115 to assess a fill level of the current state of a particular type of seed 21a, 21b, 21c, 21d, in relation to how much more seed 21 of that particular type 21a, 21b, 21c, 21d is needed in the corresponding row unit 13 to complete the planting of the current zone (s) ) VZ1, VZ2, VZ3, VZ4 (Figure 7), along the travel path, before reaching an inter-zone BND approach limit for that line unit 13.
    [025] Referring again to Figures 1 to 3 and 7, an operator first displays the PM seed type or variety prescription map (Figure 7) on the computer monitor or on the tractor interface system monitor 47, which would typically be inside the tractor cab. The PM prescription map displays which variety zones or type VZ1, VZ2, VZ3, VZ4 are located in the agricultural field and which seed types 21a, 21b, 21c, 21d can be planted in the variety zones VZ1, VZ2, VZ3, VZ4. As shown in Figure 7, in this embodiment, seed type 21a is shown to be acceptable for use in the VZ1 variety zone, which corresponds to a recommended type A. Seed type 21b is shown to be acceptable for use in the VZ2 variety zone. , which corresponds to a recommended type B. Seed type 21c is shown to be acceptable for use in the VZ3 variety zone, which corresponds to a recommended type C. Seed type 21d is shown to be acceptable for use in the VZ4 variety zone. , which corresponds to a recommended type D.
    [026] Through the tractor interface system 47, the operator enters the seed type storage information, such as which seed types 21a, 21b, 21c, 21d are stored in the bulk storage compartments 25 of (s) volume line hopper (s) 49, of the online storage system 31 (Figure 1), the bulk storage compartments 25 of the centrally located volume filling hoppers 4 and the corresponding bulk receiving compartments 53 in each unit line 13 (Figures 2), or, for bulk inline and combined central storage, bulk storage compartment (s) 25, as provided in the volume fill hopper (s) centrally located (s) 49, its corresponding volume receiver (s) compartment (s) 53 and also bulk storage compartments 25 within combined inline hoppers 71 (Figure 3). The PM prescription map can also contain the seed population that must be planted for each type or variety 21a, 21b, 21c, 21d. The seed population could also be varied within the field, based on the type of soil, organic matter, etc. The seed size can also be entered in the tractor interface system 47. This information could also be made available in the database that is built from the desktop software, when the PM prescription map is created. The operator also enters the route path information, such as selecting or (re) defining a desired planting strategy route path, across the field, while planting through the tractor interface system 47. The system Control Panel 33 used this input information to control the timing of alternation events, so that switching of different types of seeds 21a, 21b, 21c, 21d occurs substantially when the seed doser (s) 27 cross the threshold BND between zones VZ1, VZ2, VZ3, VZ4.
    [027] Still referring to Figures 1 to 3 and 7, when the control system 33 determines, from the PM prescription map, that an alternation must be made, the control system 33 commands the selector set 29 for change the release of one of the seed types 21a, 21b, 21c, 21d to a different type among the seed types 21a, 21b, 21c, 21d, which correspond to the seed type 21a, 21b, 21c, 21d that must be planted in the approach zone VZ1, VZ2, VZ3, VZ4. Referring now to Figures 1 to 3 and 6, the control system 33 can command the actuator 105 of the currently open selector valve 103 to close its selector valve 103, further blocking the flow of the type (s) of seed currently planted 21a, 21b, 21c, 21d, from the outlet (s) of the corresponding compartment (s) 81 (Figure 4). At the same time, the control system 33 can command the actuator 105 of the next required selector valve 103 to open its selector valve 103, allowing the initial flow of the respective seed type 21a, 21b, 21c, 21d, from the outlet of corresponding compartment 81 (Figure 4). When the simultaneous control system 33 commands the closing of the currently open selector valve 103 of the type of seed to be completed and the opening of the next necessary selector valve 103 of the next type of seed required, for a short period of time, there will be a mixture both the type of seed to be finished as well as the next type of seed needed in the seed reservoir 75 of the seed doser 27. When this occurs, for a short period of time, the seed doser 27 will plant a mixture of the type of seed to be completed and the next type needed in the field. This can define a TMZ transitional mixing zone crossing the BND limit zone VZ1, VZ2, VZ3, VZ4, the size of which is influenced by the time delay between closing the currently open selector valve of the seed type to be completed and the opening of the next required selector valve 103 of the next type of seed needed. The longer the delay, the smaller the volume of the mixed type of seed to be completed and the next necessary type will collect in the seed reservoir 75 of the seed dispenser 27 (Figure 4), which provides a shorter TMZ transitional mixing zone or smaller, with less planting mixed during alternation. This is due to the fact that relatively little receipt of the type to be finalized will be in the seed reservoir 75 of the seed doser 27 (Figure 4) when the selector set 29 starts releasing seeds of the next type needed in the seed reservoir 75, when the control system 33 commands such a relatively long delay. The shorter the delay, the greater the volume of the mixed type of seed to be finalized and the next necessary type that will be collected in the seed reservoir 75 of the seed doser 27 (Figure 4), providing a larger or larger TMZ transitional mixing zone. longer, with more planting mixed during alternation.
    [028] Many changes and modifications could be made to the invention, without departing from its spirit. Various components and features of the system 5, for example, components or features of the seed storage system (s), loading system and seed dosing system (s) can be incorporated alone or in different combinations in a planter or seedbed. The scope of these changes will become evident from the attached claims.
