1. Minnesota Long-Term Phosphorus Management Trials: Phase I, The Build Period Phosphorus (P) fertilizer recommendations are usually made using one of two philosophies, Build and Maintain or Sufficiency. In recent years, the Sufficiency approach has been questioned because of concerns of reducing soil test levels and yield sustainability and whether it has the same yield potential as the Build and Maintain approach. Trials were initiated in 2010 at six locations across Minnesota to develop various soil test P Interpretation Classes in replicated experiments. The initial phase... Download paper
2. Effect of Phosphorus and Potassium Fertilization on Corn Development and Root Distribution in Conservation Tillage In conservation tillage systems, like no-till (NT) and strip-till (ST), phosphorus (P) and potassium (K) typically become vertically and/or horizontally stratified in the soil. This stratification has the potential to make P a nd K less available and to limit corn yield. The objective of this study is to determine the infl uence of tillage and P and K placement and rate on soil P and K content, soil water status, root and shoot development, and grain yield of corn. The experiment was arranged in... Download paper
3. A 2020 Vision on Nutrient Use Decisions Many farmers this fall are facing significant financial stress due to several factors including low crop prices and weather-induced crop losses. Crop prices are currently much lower than they were in the first half of this decade but we have been here before … time tested principles continue to apply. Past studies of the characteristics of the most profitable farmers show that they tend to have higher yields, lower costs, and are more rapid adopters of technology than their less profitable... P.E.

4. Effects of Variable Nitrogen Fertilizer Rates on Corn Grain Yield, Profitability, and Nitrogen Losses in Southwestern Minnesota Global crop production heavily relies on the application of nitrogen (N) fertilizers, which unfortunately comes with environmental concerns. The primary pathways N is lost to the environment is through nitrate leaching into groundwater, ammonia volatilization, and nitrous oxide emissions to the atmosphere. This ongoing study started in 2021 at the University of Minnesota Southwest Research and Outreach Center in Lamberton, MN, to comprehensively assess the effects of varying N fertilizer rates... Z.J.
