A survey of no-tillers uncovers a range of application and management practices — plus uses of precision data and cover crops — that help provide optimal crop yields and cut input costs in no-till operations.
Nitrogen (N) management plans are about as variable as the timing and application options available to today’s no-till farmers. Not only is careful consideration given to the types and amounts of N applied, but the use of precision data gathering equipment also enables growers to gauge their success on the fly and take corrective actions as required.
Faced with expensive fertilizer prices, fickle weather and the threat of activist regulators, no-tillers are using nitrogen stabilizers and other nutrient enhancements more than ever to avoid the losses between application and crop uptake.
The higher the cost of the input, the more important it becomes to maximize efficiencies and make sure that input pays dividends. High fertilizer prices paired with potential environmental impact makes managing nutrient inputs doubly important.
Having no-tilled for 8 years, Tim Goodenough has moved away from using anhydrous ammonia, 28 percent nitrogen and urea as nitrogen sources. Since 2005, he’s successfully used the ESN (Environmentally Smart Nitrogen) product. This polymer-coated nitrogen is a slow release product that is activated by moisture and heat, says the West Salem, Wis., grower who no-tills 1,300 acres.
No-till corn yields comparable to those achievable with chemical nitrogen fertilizer can be produced with liquid dairy manure as the only nitrogen source — if the manure is incorporated at application, according to studies by two Ohio State University researchers.
The potential for nitrogen loss in no-till presents you with both a problem and an opportunity, maintains Sam Ferguson, a customer agronomist with Dow AgroSciences in Omaha, Neb.
