1. Evaluation of Plant-Available Phosphorus of Dried Residuals from Wastewater Processed for Phosphorus Reduction with Aluminum or IronABSTRACT Wastewater effluent from industrial and municipal water treatment plants requires phosphorus (P) removal before being discharged to surface waters. The resulting residual materials, with elevated P concentration, are usually land applied. Basing P application rates on the nutrient value for crops is the most rational way to utilize this P resource because it would improve farmers economic return while... |
2. Nitrogen Use Efficiency and Corn Yield as Affected by Applied Sulfur and Nitrogen FertilizerOverall corn (Zea mays L.) yield response, as well as nitrogen uptake and nitrogen use efficiency, can be affected by multiple factors, including the supply of other nutrients such as sulfur. The objective of this study was to evaluate the effect of nitrogen with added sulfur fertilizer on corn response parameters i) whole plant nitrogen uptake, ii) yield, and iii) nitrogen use efficiency when compared to nitrogen alone. Nitrogen Use Efficiencies evaluated in this study included i) A... T. Husa, D. Ruiz diaz |
3. Surface soil acidification and lime application in no-till systemsSurface soil acidification can develop after multiple years under no-tillage system, a primary effect of multiple years of broadcast fertilizer application and organic matter decomposition. The objective of this work was to evaluate the effects of surface lime application on crop yield response and changes in soil pH in the soil profile. Field experiments were established at two locations in Kansas and selected base on similarities in management history (approximately 30 years under no-till),... D. Ruiz diaz, B. Rutter |
