1. Effect of Nitrogen Fertilizer Placement and Sources on No-till CornNo-tillage production of corn can lead to a number of savings for growers including costs of time, machinery, labor, and energy. However, savings of soil and water are perhaps the most important attributes of no-tillage production on the sloping, erosion-prone soils found in southern Illinois, Indiana, Missouri, and Kentucky. Producer acceptance of no-tillage has not been overwhelming. Prob- lems in achieving acceptable stands, difficulties in adequately con- trolling pests of all types, especially... |
2. No-till Corn Response to N Fertilizer Sources and Placement Methods- A Summary of Southern Illinois ResultsExperiments were conducted in southern Illinois from 1984-1986 to evaluate the placement efficiency of several N fertilizers used in no-till corn production. Such information has become of meaningful importance as producers strive to obtain the greatest possible returns from their N fertilizer investment and to obtain yields and a level of profitability equal to that of more conventionally produced corn. Also, in the near future, no-tillage will become an important tool for many farmers in southern... |
3. Effect of Phosphate and Sulfate Application on Wheat (Triticum Aestivum) Grain Selenium Content and Yield ComponentsThe interest in Selenium (Se) has increased due to its potential anti-cancer attributes in human health. Wheat ( Triticum aestivum ) will assimilate Se according to soil availability. There is interest in developing a consiste nt grain supply of high Se wheat for markets in Europe and Asia since plant-available Se in soils of these continents are very low. Agricultural soils in some regions of central and western South Dakota ha ve high Se content. Yet the common plant available forms of Se, selenate... |
