Grains and field crops

This project characterizes the dynamics of nitrogen supply to a wheat crop at each of the sites on which various methods of making fertilizer recommendation were tested. It supposedly provides the "optimum" nitrogen fertilizer regime as well as detailed information on nitrogen supply and demand so that results can be made transferable to other situations.

Tactical nitrogen application for wheat
This project compares tactical and strategic methods for determining nitrogen requirements of wheat. The tactical methods depend on updating estimates of yield potential and nitrogen status of the crop as the season progresses.
