What is Adapt-N?

Adapt-N is an online software program that integrates 13 models — including local weather, soil, and crop models — to provide nitrogen planning, "what if" scenario tools, in-season whole field and variable rate nitrogen recommendations, and ways for agronomists to determine the economic and agronomic impact of field management decisions like nitrogen stabilizers, rates, and application timing. Nitrogen rates for individual fields or areas within fields are estimated based on calculated N deficit or supply.

Adapt-N was developed by Cornell University, and is operated by Agronomic Technology Corp (ATC). Norwegian fertilizer company Yara acquired ATC and the Adapt-N products in November 2017.

As of 2016, Adapt-N was available in 35 states.

Where has Adapt-N been tested?

The map below shows trial locations for corn. The trial locations have been superimposed over the Technology Extrapolation Domains (TED) Framework. The TED Framework is described further on the Adapt-N and TED Framework page.

How has Adapt-N Performed?

Trials conducted in New York, Iowa and Indiana from 2011-2014 showed a positive return to nitrogen and positive yields overall for Adapt-N when compared with farmer normal practice.  Field scale trials conducted in 2015 and 2016 in North Carolina and on NutrientStar test plots, however, while demonstrating an overall positive NUE, showed an average return to nitrogen of $-25/acre (averaged across all trial locations/years).
