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. Individual Leaf Selection to Best Represent Whole-plant Nutrient Status in Modern Corn Cropping SystemsIn modern corn cropping systems, fertilization is often required to maintain plant health. Tissue sampling is commonly utilized to evaluate plant nutrient status and determine fertilizer treatment needs. Recommendations exist on which partition/leaf to select for accurate representation of the whole-plant. Recommendations change with growth stage, suggesting to sample the whole-plant at early-vegetative stages, the top-collared leaf at late-vegetative stages, and the ear-leaf during reproductive... B.
