Abstract
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.
