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

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.

Ground following optimization with downforce control systems and methods

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 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 accumulator is added in-line with a valve on an agricultural machine and downstream of the valve. The valve is controlled to apply liquid material to a field over which the machine is traveling.

Using an accumulator to improve delivery of liquid through a valve on an agricultural machine

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. A flow meter senses a flow of liquid applied to the field. The valve control signals are generated, based on the row pressure, and the sensed flow.

Sensing flow and control of liquid application using an agricultural machine with row pressure sensors

A mobile agricultural machine has a valve controlled to apply liquid material to a field. An application assembly defines a conduit from the valve to a distal application tip. The application assembly includes a distal conduit section that has an inner diameter that is smaller than an inner diameter of a more proximal conduit section, that is closer to the valve, than the distal tip of the application assembly.
