1. Impacts of Management, Moisture, and Phosphorus Form on Phosphorus Loss Potential Phosphorus (P) is considered one of the major nutrients contributing to degradation of water quality in the United States. Our objectives were to examine P loss potential associated with: 1) high moisture conditions. 2) application (surface and incorporated) of manure from animals fed different diets and 3) sorption dynamics of inorganic and organic P compounds. The study of high moisture conditions evaluated the effects of near surface moisture conditions (wet and saturated), time (up to 28 days... Download paper
2. Applied Nutrient Management Research at Pioneer Farm As part of the Wisconsin Agricultural Stewardship Initiative (WASI). Pioneer Fann serties as an applied systems research and education fCm with a mission to collect and disseminate high- quality environmental and economic baseline data to students, producers, and regulatory personnel. This paper outlines the current farm operations, methods and types of data collection, current results from ongoing monitoring projccts and 1.esearc11, and details how the data is being used to support science-based...

3. Scale of Measurement Effects on Phosphorus Runoff Losses from Cropland As phosphorus (P)-based nutrient management planning becomes necessary for some farms in Wisconsin, it will be critical to have reliable, research-based planning tools. The Wisconsin P- hdex provides one method for preparing P-based nutrient management plans. The P-Index was developed largely from small plot-scale data showing the relationships between various site and management variables and runoff P losses. Thls study was conducted to compare runoff composition measurements at the subwatershed... Download paper
4. Manure and Fertilizer Management Influence on Soil Nutrient Levels and Grain Yields in Eastern South Dakota from 2003 to 2014 Concentrated animal feeding operations (CAFOs) are required to hold a manure management permit in South Dakota. The permit encompasses available nutrients from manure, crop nutrient use and removal, soil test nitrate-N, and phosphorus and land availability for approved nutrient application rates. The management plan determines if nitrogen or phosphorus based manure application rates are used. Most CAFO’s start out following the nitrogen based plan as soil test phosphorus (P) levels... A.

5. Corn Nitrogen Management Following Cover Crops and the Microbial Response Cover crops (CCs) may provide tools for fertilizer management and opportunities to influence soil biological communities. However, corn (Zea mays L.) growth and microbial response remain unclear when corn nitrogen (N) management strategies are practiced in combination with specific CCs. Field studies were conducted in 2015 and 2016 to evaluate the effects of no CC, Daikon radish [Raphanus sativus (L). var. The Buster], and Forage oat [Avena sativa (L.) var. Magnum]... K. Steinke, J.
