Aerway Tool Incorporates Manure
"It lets me incorporate liquid manure into any type of ground, including plowed ground, untouched corn stalks, and even hay fields," says Rick Martens, Mora, Minn., who uses a 1993 Aerway 16-ft. aeration tillage tool to custom apply manure pumped to the tractor-pulled unit through irrigation hose.
Martens bolted a manure injection manifold equipped with five 3-in. dia. drop tubes to the top of the aerator. The manifold is fed by a 6-in. dia. irrigation hose that runs direct to a liquid manure pit. He drags the hose behind the Aerway back and forth across fields up to two miles away from the pit. Manure exits the drop tubes and is fanned out by steel splash shields bolted onto the aerator frame about 6 in. ahead of the tines.
"It works better than a chisel plow because it aerates and fractures the soil without leaving big furrows and because it can be used on hay fields," says Martens. "The bolt-on tines are about 8 in. long and 1 in. wide at the base. They have a slight twist that helps fracture and loosen the soil so manure is more easily absorbed. The angle of the gang can be adjusted to vary the aggressiveness of the tines. I pull it with a Ford 8630 front wheel assist tractor that has 120 hp. I can inject up to 1,000 gallons per minute and vary application rates from 6,000 to 12,000 gallons per acre. It's a very low maintenance tillage tool so I don't have to worry about a lot of downtime.
"I had been using a chisel plow equipped with 24-in. wide sweeps on plowed ground and a traveling gun irrigator on alfalfa. However, the irrigator left manure on top of the alfalfa where it could choke the crown. Also, it couldn't reach the corners of the field and there were problems with runoff and with drift caused by winds."
He paid $7,200 for the 16-ft. Aerway.
