1. Development of Insite VRN as an Effective Nutrient Management ToolGrowers have significantly increased their yield levels in corn and wheat in the last 10 years. As yields increase. the amount of nutrients required has also increased to supply the crop with needed plant nutrition. Fertilizer application rates in excess of plant needs can increase the likelihood that the fertilizer may end up in ground water and streams. Mosaic developed a nutrient application tool, called Ins i te VRN, which illore accurately positions the fertilizer where it is needed for maximum... |
2. Development of Field InSite as an Effective Nutrient Management ToolNitrogen. phosphorus, and potassium are essential nutrients for crop production. Crop nutrient management is critical to the success of any farming operation. Land stewardship is a concern for most producers as long as yields and profitability are not affected significantly. While farmers are eager to improve the efficiency with which they apply nutrients, maintaining expected crop revenue per acre is equally important. Higher fertilizer costs have increased the desire to find better ways to apply... |
3. Soil Nitrogen Mineralization In Different Tobacco Tillage-Rotation SystemsSoil nitrogen mineralization, the microbial and biochemical transformation of organic N (e.g. proteins) into inorganic N compounds (e.g. NH 4+, NO3-), is of central importance to the nitrogen management and productivity of agricultural soil. Effects of different burley tobacco tillage and crop rotation systems on net soil N mineralization were studied, their correlation with soil organic matter, and the vertical distribution of mineralized N. Net soil N mineralization was measured by long-term aerobic... |
