An intelligent seeding and fertilizing machine for intercropping comprises: a fixed frame, a plurality of seeding devices arranged in parallel in the fixed frame and a plurality of guide columns fixedly connected in the fixed frame, where one end of fixed frame close to a cutting mechanism is provided with a lifting plate, a side of the fixed frame is in sliding contact with an inner wall of a lifting groove, the lifting groove is provided with a lifting screw, a lifting motor is fixedly connected to a top surface of the lifting plate; each seeding device includes a frame, and a bottom surface of the frame is respectively provided with a cutting mechanism, a cleaning mechanism, a furrowing mechanism, a fertilizing mechanism, a seeding mechanism and a soil covering mechanism, and the above mechanisms and the lifting motor are all electrically connected with a control system.

A planter system for planting seeds and spraying fluid includes a seeder assembly including a seed tube and a conveyor apparatus configured to propel or carry the seed through the seed tube. The planter system also includes a sensor configured to transmit a detection signal upon detection of the seed passing a detection location. The planter system also includes a control system configured to determine a travel time of the seed from the detection location to a furrow based on a baseline drop time for the seed, a baseline travel speed of the seeder assembly, and an operating travel speed of the seeder assembly. The control system is configured to transmit a control signal to a valve coupled to a nozzle assembly based on the travel time and the detection signal to spray the fluid on or adjacent the seed.

A system for controlling fan operation of an agricultural implement includes a tank configured to store an agricultural product and a conduit configured to receive the dispensed agricultural product. Furthermore, the implement includes a conduit fan configured to supply pressurized air to the conduit such that the pressurized air conveys the dispensed agricultural product through the conduit and a tank fan configured to supply pressurized air to the tank. Additionally, a computing system is configured to determine a first pressure of the pressurized air within the conduit and a second pressure of the pressurized air within the tank based. Moreover, the computing system is configured to determine a pressure differential between the first and second pressures. Furthermore, the computing system is configured to control a flow of the pressurized air supplied to the tank based on the determined pressure differential.

A method of controlling the downpressure on an air seeder that has a plurality of seed assemblies and a plurality of fertilizer assemblies each applying an adjustable downforce, wherein the method includes keeping a total downforce applied by all of the plurality of seed assemblies and all of the plurality of fertilizer assemblies less than a maximum downforce. The method may also include keeping the downforce applied by each of the fertilizer assemblies less than the downforce applied by each of the seed assemblies.

A mobile agricultural machine includes a row unit having a furrow opener mounted to the row unit and configured to engage a surface of ground over which the mobile agricultural machine travels to open a furrow in the ground. A furrow closer is mounted to the row unit behind the furrow opener and configured to engage the surface of the ground to close the furrow. A furrow sensor system is mounted to the row unit and configured to sense characteristics relative to the furrow opened by the furrow opener and generate a sensor signal indicative of the characteristics. The mobile agricultural machine can further include a control system configured to determine a furrow quality metric corresponding to the furrow sensed by the furrow sensor system based on the sensor signal and generate an action signal to control an action of the mobile agricultural machine based on the furrow quality metric.

Systems, methods, and an apparatus for distributing starter fertilizer during the planting process. In an embodiment, a starter fertilizer system is configured to apply fertilizer to a planted seed during a planting process. The starter fertilizer system includes a rudder blade, a fertilizer reservoir and a conduit. The rudder blade is configured to the dig a furrow that is offset from the planted seed. The conduit is coupled with the fertilizer reservoir and the rudder blade such that fertilizer is able to traverse from the reservoir to the rudder blade. The rudder blade is offset from each row unit such that fertilizer is expelled at a desired fertilizer location.
