While many Corn Belt no-tillers have suspected it for years, it took researchers at North Dakota State University to demonstrate how continuously no-tilled soils require less nitrogen.
Strip-tiller Larry Tombaugh combined an old cultivator, SpikeWheel units and a CDS-John Blue pump into a unit that dispenses nitrogen with low soil disturbance.
The Hula family no-tills 5,000 acres of corn, soybeans, wheat, barley and oats in four counties surrounding Charles City, Va. The 100% no-till operation is located along the banks of the James River, which flows into Chesapeake Bay where nitrogen runoff is becoming a major concern.
If conditions permit, there’s likely to be a lot of sidedressed nitrogen going on fields the rest of the month. Guy Swanson, developer of the Exactrix anhydrous delivery system, says that putting down nutrients at this time of the year can be your most cost-effective application, but there’s also a lot of risk involved if you don’t get them applied in time or properly.
Destructive trails left by a shank and knife anhydrous applicator are fodder for no-tiller nightmares. But new low-disturbance applicators mean no-tillers can slip the cost-effective nitrogen source into the ground and leave barely a mark.
Long-time no-tiller Doug Harford was among the earliest pioneering conservation farmers to break ground on drainage, yield mapping, grid soil sampling and strip-till
Back in 1973, I never thought I would be a lifetime farmer. But when Dad decided to retire, corn was $4 a bushel and nitrogen was just 3 cents per pound. The future looked bright for agriculture. Most times, it still does.
Some might consider Dan Peyton a “weekender” farmer, as he divides his time between no-tilling 300 acres of corn and soybeans and a full-time job at a nearby printing firm in Long Prairie, Minn.
I tell my neighbors that I don’t want to farm anymore. I just want to farm smarter. That philosophy was the reason we went with no-till in 1986, and it’s the driving force behind other steps that we’ve taken to make farming more efficient and profitable.
