95 Percent of Minnesota Spring Wheat Gets Nitrogen
Minnesota Ag Connection - 05/31/2016

The 2015 Agricultural Chemical Use Survey of spring wheat producers collected data about fertilizer and pesticide use as well as pest management practices in growing spring wheat.

Fertilizer refers to a soil-enriching input that contains one or more plant nutrients, primarily nitrogen (N), phosphate (P2O5), and potash (K2O). Of the three primary macronutrients, nitrogen was the most widely used on spring wheat planted in Minnesota according to the latest USDA, National Agricultural Statistics Service -- Agricultural Chemical Use report. Farmers applied nitrogen to 95 percent of planted acres at an average rate of 105 pounds per acre per year. Macronutrients phosphate and potash were applied to the majority of acres, at an average rate of 38 and 34 pounds per acre per year, respectively. The secondary macronutrient, sulfur, was applied to 30 percent of acres planted to spring wheat.

The pesticide active ingredients used on spring wheat are classified in this report as herbicides (targeting weeds), insecticides (targeting insects), fungicides (targeting fungal disease) and other chemicals (targeting all other pests and other materials, including extraneous crop foliage). Herbicide active ingredients were applied to 97 percent of the spring wheat acres planted. Tebuconazole was the most widely used pesticide overall, and MCPA, 2-ethylhexyl was the active ingredient with the greatest total amount. Fungicide and insecticide active ingredients were applied to 76 percent and 41 percent of spring wheat acres planted, respectively

Rotating crops during the past 3 years was the top pest management practice for the spring wheat acreage in Minnesota.
