N-WATCH is a management tool that provides insight to the dynamics of plant-available (nitrate and ammonium-N) in the upper two feet of the soil profile over time. It is a tool that can be used to estimate the concentration of plant-available N as the year progresses at a point. N-WATCH should stimulate new questions about the 4Rs of nitrogen and serve as a tool to help farmers Minimize environmental impact through Optimizing harvest yields and Maximizing N utilization, a focus on M.O.M.
