1. Are We Getting Better at Supplying Corn with Nitrogen?While the MRTN approach to making N rate guidelines is an improvement over previous methods, there remains the question about whether or not the database is sufficiently large to support the results adequately. This question is brought into focus when N rates used according to the MRTN guidelines are seen (or at least perceived) as being be inadequate in a given field or area in a given year. Other entities now making N rate recommendations may also market against the MRTN approach by raising doubts... |
2. Maximizing Yield, Income, and Water QualityThose involved with Midwest production agriculture are aware that applications of nitrogen fertilizer can have unintended consequences upon water quality. It is our focus to minimize the potential of such environmental risks by working together to optimize harvest yields, and to maximize nitrogen utilization through the use of science-based initiatives, such as development of nitrogen management systems and N-WATCH. Sustainability of voluntary efforts to minimize the environmental impact of nitrogen... |
3. Maximizing Yield, Income, and Water QualityTo improve farm profitability and minimize environmental impact of nitrogen (N) use by reducing N losses and increasing harvest yield. Nitrogen Management System: A planned approach to N use that achieves better plant utilization and higher harvest yield with less environmental loss. It promotes a multiple application approach to N Management. It reduces early N application rates while emphasizing post-emerge N nutrition. It is about making incremental N applications that will Minimize environmental... |
4. Maximizing Yield, Income, and Water QualityN-WATCH is a management tool designed for N Management Systems to inventory, track, and verify plant-available N in the soil. N Management Systems hedge the risk of N loss by splitting up the N application following the 4Rs of Nutrient Management (Right source, Right rate, Right time, and Right place). It is all about Minimizing environmental impact by Optimizing harvest yield, and Maximizing nutrient utilization. It is all about focusing on M.O.M. Who is eligible: Ag Producers that are adopting... |
5. Maximizing Yield, Income, and Water QualityA program sponsored by the Illinois Council for Best Management Practices (CBMP) to provide local growers an estimate of the location, form, and concentration of plant- available N remaining in the soil. Plant-available N at a point in a field and a point in time can be estimated utilizing this technique and provide information that may help minimize environmental impact by improving harvest yield and maximizing nitrogen utilization. (This is not to be used as a stand-alone N recommendation system.)... |

7. Soybean Yield Response to Nitrogen and Sulfur Starter Fertilizers Under Conservation TillageContext: No-tillage and cover crops adoption remain limited across the U.S. North Central region due to concerns about potential yield penalties in cash crops. High residue levels can slow soil warming and mineralization and promote nutrient immobilization, often leading to limited early-season nitrogen (N) and sulfur (S) availability for soybean. Objective: Evaluate soybean grain yield response under different tillage systems and assess the potential of N and S starter fertilization... F. Rolle, G. Preza fontes, D. Schaefer, J. Vossenkemper |
8. Soybean Response to Tillage, Row Spacing and Nutrient Management Practices in Southern IllinoisConservation tillage improves long-term soil health and water quality but may reduce early soybean (Glycine max L.) growth due to cooler, wetter soils and limited nutrient availability. This study evaluated integrated management strategies, including tillage, row spacing, and starter nitrogen (N) and sulfur (S) fertilization, to optimize soybean performance under Illinois conditions. Field trials were established in 2024 in southern Illinois. Two split-plot experiments were conducted:... E. Brevik, A. Sadeghpour, F. Rolle, D. Schaefer, G. Preza fontes, M. Javid |
