A nitrogen fertilizer composition includes urea and a nitrate-based fertilizer such as ammonium nitrate, calcium ammonium nitrate and mixtures of ammonium nitrate and calcium ammonium in which the urea and total nitrogen are at concentrations of 20 percent by weight or greater and the concentration of ammonium nitrate is at 30 percent or greater by weight. One or both of the urea and nitrate-based fertilizer are coated with an agriculturally compatible material. The fertilizer composition provides significant nitrate nitrogen for legitimate agricultural use yet is not amenable to the production of an explosive by crushing or by aqueous extraction. A …

Most wheat producers in Kentucky apply nitrogen (N) as a split application. The first N increment is applied when wheat plants begin actively growing (green-up) in late winter, which is typically in mid- February between growth stages Feekes 2 to 3. The second N increment typically occurs in March when wheat is between Feekes 5 to 6. Many producers in Kentucky, especially Western Kentucky, have become accustomed to beginning first N applications in late January when the ground is frozen and the wheat is still dormant. This practice allows them to apply N to large acreages of wheat while avoiding …
Grassland Renovation And Consequences For Nutrient Management, Johannes Isselstein, Manfred Kayser
Grassland Renovation And Consequences For Nutrient Management, Johannes Isselstein, Manfred Kayser
IGC Proceedings (1997-2023)
Sward degradation is a serious threat to the functioning of grassland and the provision of ecosystem services. Renovation measures are frequently applied in order to restore degraded swards. However, the success is highly variable and substantial tradeoffs are often found following renovation such as among agronomic and environmental services. Starting from a general classification of renovation measures the paper investigates the processes induced by renovation that lead to a change of the vegetation and that affect carbon and nitrogen fluxes. These processes are strongly interrelated and dependent on site, climate and management condition as well as on the time scale. …
