Beta-testing the Adapt-N Tool in On-farm Strip Trials

IPNI-2012-USA-NY10

This project aims to increase adoption of adaptive nitrogen (N) management for corn production using better rates and timing of application. The new Adapt-N tool provides N fertilizer recommendations adapted to the spring rainfall and temperature conditions of the current season, using high-resolution weather data, a sophisticated computer model, and field-specific information on soil properties and soil and crop management.

Interpretive Summary

Optimum nitrogen (N) fertilizer application rates for corn vary from year to year due to weather. Many current N rate recommendations do not account for this variability. Several major consulting services are beginning to offer services that address weather variability. The goal of this project was to validate a computer model-based tool that provides N fertilizer recommendations adjusted to the spring rainfall and temperature conditions of the current season.
