Duck Foot Injector For Liquid Manure
"One of the mistakes you can make with liquid manure is to surface apply it without injecting it into the soil. Next worst is to inject it too deep," says engineer Ron Hettinga who has developed a new "duck foot" injector for shallow injection.
Manufactured and marketed by Loyal Equipment, of Guelph, Ont., it's equipped with gauge wheels to maintain a constant depth which is adjustable from 3 to 6 in. "We've discovered that a depth of 4 in. to 5 in. is ideal for getting maximum crop yield benefit," says Hettinga. "Limited trials indicate we can expect a 10 to 14% boost in corn yields with shallow 4 in. injection, versus deeper injection of 10 to 12 in."
Loyal Equipment has introduced a 4-shank shallow injector equipped with the new-style "duckfoot" shovels, that fits most gravity or vacuum tanks. It takes a 10 ft. swath, is adjustable for row width, and applies up to 600 gals. (U.S.) per minute at 4 mph. Requires 5 hp. per shank.
Sells for right at $4,500 with a hydraulic-driven pump, $3,000 without (Canadian dollars).
