1. Should We Abandon Soil Testing and Yield Goals in Estimating Nitrogen Rates for Corn

If the prices of corn and fertilizer-N and the shape of the N response function relating crop yield to the amount of fertilizer used are known, calculating an economically optimal N rate (EONR) for maximizing the net return to applied N is straightforward: the EONR is the N rate at which no firher increase in net return occurs. In most cropping systems and under common price scenarios, crop yield at the EONR is within 95 to 99% of the maximum yield obtained for the specific management package. In...

2. Evaluation of Plant Tissue Analysis to Assess Phosphorus Nutritional Status in Corn and Soybean

Plant phosphorus (P) tissue analysis can be used to identify the nutritional status and potential response to P fertilization. This study aimed to determine critical P tissue concentration at different growing stages for corn and soybean. The experiment was conducted across multiple corn and soybean locations in Kansas. Tissue samples were collected as whole plant V6 stage and ear leaf R1 stage in corn, whole plant V4 stage, and trifoliate R3 for soybean. Plant tissue samples were dried, ground,... G. Roa, D.
