He Plants Corn and Applies Anhydrous at the Same Time
An anhydrous ammonia injection system mounted on a White 8-row 30-in. planter lets Martin Thomas, Morganfield, Ky., apply anhydrous as he plants.
Thomas clamped nine anhydrous knives to the planter toolbar, centering them between the planter units to eliminate crop injury. The knives place anhydrous 6 to 8 in. deep with depth regulated by the planter transport wheels. A 1,000-gal. anhydrous tank is pulled behind the planter.
"I got the idea because I have 1,700 hogs and farm 350 acres of row crops by myself with only one large tractor. I had been sidedressing anhydrous or applying it preplant, which meant I had to make separate trips for each operation. Now I can apply anhydrous and plant corn at the same time when the soil is in near perfect condition for both. I think this system would work on any toolbar planter."
Thomas uses a flow-divider on each end knife to cut the anhydrous application rate in half. When the planter turns at the end of the field, the end knife returns in the track it made on the preceding pass. He uses a standard metering mechanism to regulate the application rate. He can quickly remove the knives from the planter when not needed. He notes that pulling the planter, anhydrous knives, and tank gives his 200 hp tractor about all it can handle.
