1. Evaluation of the Amino Sugar-N Based Soil test in Iowa Corn ProductionAn important improvement in estimating economic N applications for corn production would be to predict the soil N supply capacity each year. The objective of this research is to evaluate the adaptability and potential calibration of the amino sugar-N based Illinois N Soil Test in corn production fields across diverse Iowa soils. Nitrogen rate trials were conducted at multiple sites over several years, many on producer fields. Soil samples were collected at 0-6 and 0-12 inch depths in the fall and... |
2. Assessing the Benefits of Radish as a Cover CropOilseed radish (Raphanus sativus L) is a popular cover crop for no-till farmers in Wisconsin, especially among those that include winter wheat in rotation since radish can accumulate large amounts of nitrogen (N). However, previously presented research in Wisconsin has not shown a clear N credit for a subsequent corn crop. Additionally, there is a lack of information that quantifies other benefits of radish, including compaction reduction and nematode suppression. The objective of this project was... |
3. Fertilizer Management of Soybean in Northwestern and Northcentral North DakotaSoybean (Glycine max L.) is a new cash crop for northcentral and northwestern North Dakota (ND) producers. Soils and climate in these new soybean areas differ from current fertilizer guidelines. North central and northwestern ND is more undulating, arid, cooler, and has differing soil pH. A three year study to evaluate soybean best management practices was initiated in the spring of 2016 and will be concluded in 2018. Each year had two sites and twelve treatments. One site was acidic (pH... C. Augustin, D. Franzen |
