Slowing slurry flow

Precision manure application used to be an oxymoron, since it was nearly impossible to accurately regulate an even spread across your fields.

Ag engineers at the University of Illinois recently unveiled an adapted pneumatic pinch valve connected to a computer that automatically adjusts air pressure to ensure proper, constant flow rates. The technology is designed for use with suction pressure manure tank equipment.

Future refinements include the addition of global positioning system monitoring to the unit. This will allow you to apply manure according to field test results or be able to program the valve to shut off when the equipment gets too close to a stream or well.
