Evaluation of an Organic Copolymer Fertilizer Additive on Phosphorus Starter Fertilizer Response by Corn

摘要

Fertilizer additive products have recently been developed with the intention of reducing phosphate fixation and improving phosphorus plant availability. The objective of this study was to evaluate corn plant growth and grain yield response to starterP fertilizers applied with and without AVAIL on sites ranging in initial soil test P (STP).
