Locations of seeds in a field can be identified. A material is applied to the field by an agricultural machine, based upon the seed locations. The placement of the material is detected and the agricultural machine is controlled.

Systems and methods for selective material placement, sensing, and control

An agricultural machine applies liquid material to a field. Valve control signals control valves to apply the liquid material. Row pressure on the agricultural machine is sensed to identify when the valve is opened to apply the liquid material. The valve control signals are generated, based on the row pressure, to control the valves to apply the liquid material at a desired location in the field, relative to plant locations in the field.

Sensing and control of liquid application using an agricultural machine

A seeding machine () includes a seeding mechanism () driven by a seeding motor (). A motor command signal is compensated for accelerations based on a wheel based speed of a towing vehicle ().

Acceleration compensation in controlling a seeding machine

Furrows can be opened in a field. Seeds can be delivered to the furrows in the field at different locations in the field. The locations of the seeds in the field can be identified using different types of processing. The different types of process can include event-based processing or frequency-based processing. A material is applied to the field, based upon the seed locations.

Systems and methods for selective material placement

An agricultural machine includes a seeding system having a seed meter configured to meter seed, a seed meter sensor configured to generate a sensor signal indicative of movement of the seed meter, and an assistive seed transport mechanism configured to receive the metered seed from the seed meter and to transport the metered seed along a delivery path. A control system is configured to determine a position of the seed in the assistive seed transport mechanism based on the sensor signal, and generate a control signal to control the agricultural machine based on the determined position of the seed.

Agricultural seed detection and tracking system

An agricultural row unit adapted to be moved over soil by an agricultural planter to clear crop residue includes a residue clearing disk or brush. The row unit may include a motor to drive rotation of a crop residue disk or brush. The agriculture row unit may also include a controller configured to adjust the operating speed of the motor in response to factors internal and/or external to the agricultural row unit. The factors may include at least one of a speed of the agricultural planter along the row, a height of crop residue disk or brush the relative to a surface of the soil, a height of the crop residue disk or brush relative to a surface of the soil, amount of crop residue in the row, and a downforce pressure on the row unit.

Powered clearing-disks, control system, and method of use

An indication of previously-applied material is obtained. A planting machine is controlled to plant seeds based on the indication of the previously-applied material.

Controlling seed placement based on prior material placement

Locations of seeds in a field can be identified using event-based processing or frequency-based processing. A material is applied to the field, based upon the seed locations.

Systems and methods for selective fertilizer placement

An agricultural machine includes a main frame, an adjustable frame coupled to the main frame and, a row unit which includes a linking arm coupled to the adjustable frame, and an actuator coupled to the main frame and the adjustable frame. The agricultural machine also includes a controller configured to command the actuator to output various downforces to the row units based on signals received from one or more sensors. The one or more sensors are configured to measure one more indicators associated with an actual height of the row unit relative to ground.

The agricultural machine also includes a controller configured to command the actuator to move to various positions based on signals received from one or more sensors. The one or more sensors are configured to measure one more indicators associated with an actual height of the row unit relative to ground.

Ground following optimization with position control systems and methods

An implement includes a frame having a main section and a wing section pivotally coupled to the main section. A row unit is mounted to the frame wing section to dispense a product to the ground surface. A weight transfer system transfers weight from the frame main section to the frame wing section to reduce the load carried by the main wheel assembly. A row unit downforce system applies a force on the row unit relative to the frame wing section. A pressure transducer measures the force applied by the row unit downforce system and generates a signal indicative of the applied force. A control system operates the weight transfer system in response to the signal from the pressure transducer to assist the row unit downforce system. The control system actuates the weight transfer system to apply an additional force on the frame wing section in response to the signal.
