1. Chemical and Biological Changes Resulting from Soil Submergence Flooding of a soil for rice production results in significant short and long term physical, chemical and biological changes in soil properties. These changes may have significant impact of the availability of nutrients for plant growth both for aquatic plants growing in the flooded soil and upland plants on the soil when not under flooded conditions. Chief among these nutritional effects are accelerated nitrogen (N) losses, conversion of phosphorus (P) to more available forms during flooding then... Download paper
2. Exploratory analysis of event-based edge-of-field phosphorus losses Understanding 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. Carbon Credit and Sequestration in Agroecosystems; Lessons from Trials in Southern Illinois A carbon (C) credit is the attribution of net CO2-C equivalent which can be used to decrease climate forcing through a given practice or farming system for a given unit time. Carbon credits allow industries to purchase C that is produced on a farm (i.e., offsets). Carbon can be captured in two ways; (i) by capturing and reducing greenhouse gasses (on a CO2-C equivalent basis), and/or (ii) by increasing soil organic C stocks. Therefore, to enable C credits in the agricultural... A. Sadeghpour, A.M. Weidhuner, G. Burkett, O. Zandvakili, O. Adeyemi, C. Kula, J. Berberich, J. Pike, A.J. Margenot Download paper
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.
