1. Better Maize Response to Optimal Fertilizer PlacementIncreasing trends in corn (Zea mays L.) yields require greater levels of applied nutrients per acre to maintain or increase yields; thus, we need to rethink how to best supply a crops⤙ required nutrients. One significant challenge associated with applying more fertilizer to support greater yields has been the negative environmental effects of increased levels of some nutrients, such as phosphorus. Fertilizer application technologies such as banding the fertilizer below the plant increases... |
2. Is There a Better Way to Fertilize Corn with Potassium?Potassium (K) is among the most abundantly needed plant nutrients. A 15.7 Mg ha-1 (250 bushel acre-1) corn (Zea mays L.) crop accumulates anywhere from 168-225 kg K2O ha-1 (150-200lbs K2O acre-1) over the course of a growing season, and according to the IPNI Soil Test Summary (2015), about 37% of Illinois’ soil tests are deemed as deficient for K. The objectives of this study were to investigate various methods of... S. Foxhoven, F. Below |
3. Maize Yield Increased by Optimal Timing and Placement of Polymer-coated Nitrogen FertilizerNitrogen (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 |
