Project Description - Impacts of 4R Nitrogen Management on Crop Production and Nitrate-Nitrogen Loss in Tile Drainage

Project Objectives As part of this field research and demonstration project, we propose to evaluate various promising N management methods and technologies by documenting the nitrate-N export and crop ...

Project Description - Supplemental Late-Vegetative Nitrogen Applications for High-Yield Corn: Agronomic, Economic and Environmental Implications with Modern Versus Older Hybrids

Introduction: Modern corn hybrids have a “functional stay green” capacity whereby their leaves not only stay green longer during the grain filling period, but also maintain their photosynthetic capaci ...

Project Description - Minimizing Phosphorus Loss with 4R Stewardship and Cover Crops

Project Goal: The goal of this project is to protect water quality and maximize nutrient use efficiency while simultaneously providing producers with flexible management options for phosphorus (P) fer ...

Project Description - Evaluating the 4R Nutrient Stewardship Concept and Certification Program in the Western Lake Erie Basin

Since the mid-1990s, the frequency and extent of algal blooms and loadings of dissolved phosphorus (P) in the Western Lake Erie Basin (WLEB) have been on increasing trends. Agricultural crop managemen ...

Meta-analysis of Enhanced Efficiency Fertilizers in Corn Systems in the Midwest

Enhanced efficiency fertilizers can be an effective means of managing nitrogen to prevent losses to the environment, both to protect natural resources and improve crop yields. However, the range of en ...
