1. Tank-Mixing Micronutrients Fertilizers with Glyphosate- Potential Problem or Efficient SolutionsTANK-MIXING MICRONUTRIENT FERTILIZERS WITH GLYPHOSATE - POTENTML PROBLEM OR EFFICIENT SOLUTION Mark L. Bernards, Kurt D. Thelen, Donald Penner Michlgan State University, East Lansing, MI Summary: Many agribusinesses are currently promoting the application of micronutrient foliar fertilizers in tank-mixtures with glyphosate for increased efficiency in glyphosate-resistant soybean production. This practice is inconsistellt with data which shows decreased glyyhosate efficacy in the presence of the hard-water... |
2. Organic Farming in Nebraska: Establishing Organic Research for the Organic Farming CommunityFour sites in Nebraska were developed to have land available to conduct research on certified organic land. All sites will be certified organic by the end of 2008. The goal of the project is to conduct research relevant to the organic farmi ng community and not to compare organic systems with conventional systems. Resear ch is being conducted on the use of flaming to control weeds, winter wheat variety development and selection for the organic market, variety testing of organic winter wheat, proso... |
3. Soybean foliar manganese recommendations on chronically Mn deficient soils.Soil Mn availability decreases with increasing pH and organic matter concentrations, leading to seasonal Mn deficiency symptoms in soybeans pr oduced on these soils. In Michigan, high pH conditions are often found in alluvial calcareous lakebed soils where conditions lead to low Mn solubility. High organic matter co ncentrations in organic soils reduce Mn availability due to formation of unavailable chelated Mn 2+ compounds and organic complexes in the soil. While Mn deficiencies on lakebed soils... |
4. Cover Crops and Tillage Interaction on Claypan Soils of Southern IllinoisIncreased nutrient leaching due to agricultural practices such as tillage and fertilization is a significant environmental concern. Nitrogen (N) mineralization stimulated by tillage can increase the risk for nitrate leaching before subsequent crops have an opportunity to take up the N released by microbial activity. An alternative measure for reducing potential nutrient loss via leaching and runoff is use of cover crops (CCs). A field experiment was conducted at the Southern Illinois University’s... S.

5. The Effect of Agricultural Management Practices on Labile Soil Carbon and Nitrogen in WisconsinAmid ever-increasing enthusiasm for soil health there remains uncertainty about how best to measure it, to interpret the results, and to adapt agricultural management accordingly. One factor of particular interest to farmers is the capacity of a soil to mineralize organic matter, making nutrients available to crops. This research takes a survey-based approach to identify how labile carbon (C) and nitrogen (N) – as permanganate oxidizable carbon (POxC), potentially mineralizable carbon (PMC)... G. Richardson, M.
