EVALUATING THE RETURNS TO VARIABLE RATE NITROGEN APPLICATION
Provedor de dados: 31
Autores: Roberts,   Roland K.; English,   Burton C.; Mahajanashetti,   S.B.
Potential benefits of variable rate nitrogen application are illustrated and information needs identified. Lower costs of precision farming services, higher crop prices, and greater divergence in yield response potentials across management zones reduce the spatial variability required for profitable variable rate application. Information needs include identification and measurement of management zones within a field and estimation of management zone yield response functions, crop and input prices, and the cost of precision farming services.
