1. Manure, Phosphorus, and 125 Site-Years of Edge-of-Field Runoff MeasurementsPhosphorus export from agricultural fields continues to create water quality concerns in Wisconsin. The UW Discovery Farms program, along with Discovery Farms Minnesota have collected 125 site-years of edge-of-field monitoring datawhich can be used to better understand the relative effects of inherent soil properties (slope, drainage class, texture), management practices (manure application, tillage, crop rotation, cover cropping), and soil test P values on seasonal (frozen and non-...

2. Exploratory analysis of event-based edge-of-field phosphorus lossesUnderstanding how the timing of management activities, particularly manure and fertilizer applications, impacts P losses in runoff can improve farmers’ decisions on when to apply nutrients. The University of Wisconsin Discovery Farms and Discovery Farms Minnesota have been monitoring edge-of-field nutrient losses since 2004. This data set includes over 125 site-years of runoff across 26 fields and includes 1574 individual runoff events. The objectives of this study are to: (i) determine... |
3. Versatility of Mycorrhizal Fungi Applications to Increase Maize ProductivityWith rising fertilizer prices and continual water contamination issues, it is vital to establish management factors that maximize productivity, while minimizing nutrient losses to the environment. One potential practice for improving nutrient use and grain yields includes utilizing mycorrhizal fungi. The objectives of this research were to determine the efficacy of various mycorrhiza applications on root colonization and the subsequent grain yield responses of maize (Zea mays... L. Woodward, F.
