Given the high cost of Nitrogen (N) fertilizer and a tendency to apply the majority of N prior to planting, growers stand to potentially leave a lot of money on the table by failing to optimize their N-management in small grain systems. For example, early, heavy rains last year flushed a lot of nitrate out of the soil profile before wheat could take it up during the rapid growth phase. In-season applications provide an opportunity to take account of the water year, and the crop status before deciding on a season-long N fertilizer budget.


The Nitrogen Fertilizer Management Webtool for California Wheat offers in-season insight on whether and how much N to apply given the seasonal conditions. While the use of the webtool is pretty straightforward, we have found that it is helpful to offer workshops to help CCAs and growers become more familiar with its use. These two-hour trainings offer an introduction to principles of N-management in wheat and use/ interpretation of the webtool.
