1. Developing a Natural Resource Web Site as a Training Tool for Students and AgronomistsSouth Dakota State University. Brookings SD Introduction South Dakota agronomists, agricultural workers, and students often require visual aids to demonstrate a field procedure or understand the interaction among natural resources that contribute to agricultural production. Suitable commercial products are available to serve this purpose, but they may be neither readily accessible to the public, nor particular to the state. An Internet site accessible to the public is required to display aspects... |
2. Agronomic and Nutrient Cycling Responses in a Rotation StudyA twelve-year rotation study was established in the Divide soil near Brookings SD in 2000. Treatments of crop rotations (corn-soybean, s oybean-spring wheat, and corn-soybean-spring wheat), tillage (conservation till vs. no-till), and residue management (post-harvest residue removed vs. residue returned) were established. Grain yield, residue crop residue production, nutrient cycling, and carbon storage responses were documented. Mean grain yield for various crops was not significantly influenced... |
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... |
