Predicting agronomic rates is important to derive optimum economic and environmental benefits from biosolids fertilizer applications. We conducted this research to 1) evaluate dryland wheat response to biosolids applications over a range of climate zones in the Pacific Northwest and 2) compare agronomic application rates predicted from yield curves with...
The use of management units for soil testing and nutrient application is an
effective strategy to increase accuracy in monitoring and managing nitrogen (N), phosphorus (P), and other nutrients. A management unit can be a group of fields, a single field, or an area within a field. To measure changes...
