Web-based decision support tool provides field-specific N recommendations in real time, in-season.

  • Suited for desktop, tablet or smartphone (browser).
  • Computer model reflects latest weather conditions, soil type and plant-N-uptake physiology model every 24 hours. Modifies recommendations as weather and field conditions evolve, in real time.
  • Determines if manured fields need additional N.
  • Determine if you need rescue N after heavy spring rains, and/or as other variables change.
  • Identifies remaining N after the growing season.
  • Improved corn-growing profits in 86% of 2011 trials, by an average of $35/acre.
  • Enables what-if planning.
  • Available this year in Iowa, Illinois, Indiana, Minnesota, Wisconsin and the Northeast.
  • One New York pilot farm had a 140-lb./acre N rate difference between conventional recommendation methods, with no lost yield. The same site also reduced its 2011 N leaching losses by about 77%, from 142 to 32 lbs./acre.
  • Replicated trials in Iowa decreased N rates by 45 lbs./acre on average and increased grower profits in 78% of cases. N losses to the environment were decreased by 5-120 lbs./acre.
  • Adapt-N has been presented at conferences held by the North Central Extension-Industry Conference, the National Alliance of Independent Crop Consultants, the Iowa Soybean Association On-Farm Network, Iowa State University’s Integrated Crop Management, the Soil and Water Conservation Society and the American Society of Agronomy.
