Marion Calmer goes through his 40-year journey of replicated studies on nitrogen rates, row spacings, populations, tillage vs. no-till vs strip-till, residue management and most recently the long-term effects of surface-applied phosphorus and potassium.
David Wessel’s recipe for no-till success lets him wring out profits from poorer ground and lean on covers and healthier soil to raise corn, soybeans and wheat more economically.
South Dakota State University researchers discuss a field-scale, replicated trial testing different fertilizer nitrogen rates on sorghum last year utilizing both standard and Rick Haney soil tests to develop recommendations.
Concerns among no-tillers about the impact of high nitrogen (N) rates on soil acidity appear to be on the increase. And it’s more of a problem with continuous no-till since some growers are spreading less lime due to increasing soil organic matter and decomposition.
Manured fields are good candidates for the pre-sidedress soil nitrate test, but nitrogen credit following legume crops is unpredictable and will likely depend on the stand density and timely termination.
The nitrogen rate within a particular field for corn, wheat or sunflower is important, but nitrogen rate isn't related to yield over different sites, according to a soil specialist at North Dakota State University Extension.
Predicting the optimum nitrogen rate for wheat is difficult, but Michigan State University Extension offers some considerations that may help growers determine a reasonable estimate.
The University of Minnesota Extension provides guidelines developed through years of unbiased research to help growers make the best decisions for their nitrogen management.
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.
