There was little yield response to either P or seeding rates and no important differences in the response by landscape position. There was a good yield response to N and the response was greater on the lower slopes than the upper slopes. However, a simple economic analysis showed that there was no economic advantage to varying the N rate by landscape position and, in fact, an economic disadvantage to varying N rate when using a single N-P fertilizer blend.enAttribution-NonCommercial-NoDerivs 2.5 CanadaPresentation
