1. Variable Fertilizer Nitrogen Application Based on the Delta Yield Index- A Field Study A quick review of the both the scientific and popular literature indicates that many different approaches have been suggested for the prediction of variable fertilizer N applications in the field. In previous meetings of this conference we have presented the general outline and approach taken for our site-specific crop management project in Ontario. Briefly, historical data sets of grain corn response trials to fertilizer N (encompassing some 300 site-years worth of data) indicated that most yield... Download paper
2. Manure Source and Rate Effects on Soil Test Levels and Corn Growth Nutrient management planning has become an important tool in an effort to improve water quality. In Wisconsin, nutrient management regulations are in the process of moving to a phosphorus (P) based standard. As such, P budgeting and the P index will greatly influence manure applications. Thus, there is a need to better understand how soil test P changes with respect to a P based manure application. In Wisconsin, only 60 % of the total P applied in manure is considered to be available to the crop... Download paper
