1. Site-Specific Management of Iron Deficiency in CornThe addition of FeS04mH20 in the seed row increases corn (Zea mays L.) yield in areas with Fe deficiency-induced chlorosis. Our objectives were to determine the correct application rate of FeS04.H20 for irrigated corn, identi9 the spatial distribution of Fe deficiency, and alleviate deficiency symptoms with targeted FeS04.H20 applications. Eleven site-years were selected for small-plot studies in western Kansas. At these fields, soil CaC03 content in chlorotic or problematic deficient areas of the... |
2. Root Growth and Phosphorus Uptake Affected by Fertilizer Management in Soybean and WheatPlant root growth patterns can be affected by nutrient and water availability. The objective of this study was to assess the effect of phosphorus (P) fertilizer management on soybean (Glycine max. L) and winter wheat (Triticum aestivum L.) root system growth and macro and micronutrients uptake. Two greenhouse studies were carried out at Kansas State University, Manhattan, Kansas under controlled environment. The experimental design... F. Hansel, D. Diaz |
3. Soybean Growth and Yield Effects from Starter Fertilizer and Nitrogen ApplicationSpring Michigan weather variabilities and earlier planting dates may provide opportunities for starter fertilizer to affect soybean (Glycine max L) early season dry matter production while also decreasing the time interval for nutrient accumulation (i.e., lag-phase), but impacts on initiating biological N fixation (BNF) are not well known. Two trials were established near Lansing, MI to examine the effects of starter fertilizer and multiple nitrogen (N) application timings across two... K. Steinke, S. Soat |
4. Soybean Biological Nitrogen Fixation and Production As Affected by Starter Fertilizer, Nitrogen Application, and Planting DateMichigan spring weather variabilities and earlier planting dates may provide opportunities for starter fertilizer to influence early season soybean (Glycine max L. Merr.) dry matter production while simultaneously decreasing the time interval for nutrient accumulation. However, potential fertilizer impacts on inhibition of biological N fixation (BNF) are not well understood. Field studies established near Lansing, MI examined soybean total dry matter accumulation (TDM), nodulation, 15N... K. Steinke, S. Soat |
