1. Maize Yield Increased by Optimal Timing and Placement of Polymer-coated Nitrogen Fertilizer

Nitrogen (N) fertilizer application timing and placement can manage N availability to improve maize (Zea mays L.) productivity, but polymer-coated N fertilizer offers a different approach to season-long N availability and creates new N management opportunities. The objective of this study was to compare the effectiveness of conventional and polymer-coated N sources across fertilizer timing and placement combinations to optimize maize productivity. Field trials were conducted at three... S. Schwartz, F. Below
