Manure Tank Aerator Increases Manure Absorption
"After we mounted a 12-ft. Aerway aerator on the back of our liquid manure tank, yields increased and our test plots had 21 lbs. of extra nitrogen per acre compared to plots where manure was broadcast without the use of an aerator," says John Van Dorp, Woodstock, Ontario.

Manure Tank Aerator Increases Manure Absorption MANURE HANDLING Equipment 19-1-12 "After we mounted a 12-ft. Aerway aerator on the back of our liquid manure tank, yields increased and our test plots had 21 lbs. of extra nitrogen per acre compared to plots where manure was broadcast without the use of an aerator," says John Van Dorp, Woodstock, Ontario.
Van Dorp came up with the idea as part of a government-funded manure study. He had previously broadcast manure with his WIC spreader, or injected manure using 4 injector shanks mounted on a toolbar at back of the spreader.
To fit the tank with the aerator, he re-moved the injector toolbar and replaced it with the 12-ft. Aerway toolbar. He then installed a hydraulic cylinder at center that applies up to 4,800 lbs. of down pressure on the aerator. He installed an accumulator valve, taken from a 7720 Deere combine, to allow the Aerway and the hydraulic cylinder to absorb the shock of hitting stones or dead furrows without breaking.
"All of our manure plots put in with this setup out-yielded plots fertilized with conventional fertilizer. Down pressure on the Aerway decreased compaction by the tanker wheels, transferring weight to the tractor hitch," notes Van Dorp.
