1. Small Grain Response to Potassium and Chloride AdditionsStudies have been conducted over a three-year period to determine the frequency and the cause of small grain response to KC1 additions on high K soils. During the first two years responsiveness of hard red spring wheat, spring barley, and oats were compared at six locations in eastern South Dakota. Broadcast applications of 167 lbs/A of KC1 caused grain yield increases significant at the 0.05 probability level at four sites for wheat and two sites for barley while no oat yield increases were measured.... |
2. Effects of Residue Density, Strip Tillage, and Starter K on No-till Corn Grown in Wheat StubbleField studies were conducted in 1992 to 1994 at 2 locations in southern Illinois to evaluate the influence of wheat straw residue density and stl-ip-tillage vs no-tillage on corn growth and yield. Corn growth and resultant yield is frequently reported by producers to Se depressed in the residues of a previous wheat crop. Allelopatliy is thought to be at least partially involved. The objective of the research was to evaluate straw level (removed, remain non-modif ied, and doubled), strip tillage,... |
3. Incorporating Cover Crops into No-till Production SystemsAlthough no-till soil management has many benef its, including protecting the soil from erosion, improving soil organic matter, and improving soil moisture storage, depending on environmental conditions there could be a number of potentia l problems. Implementation of no-till soil management in eastern South Da kota can lead to wet and cold soils at the time of planting. Cover crops have the potential to utilize exce ss soil moisture and improve soil conditions at planting. A field experiment was... |
4. Corn Responses to Sulfur Fertilizer in IndianaCorn yield increases in response to sulfur (S) applied as ammonium thiosulfate in liquid N (in sidedress and/or starter fertilizer applications) occurred in ~40% of 40 trials conducted between 2017 and 2021 and ranged from 4 to 24 bushels per acre on responsive sites. Increased grain yield with S fertilization occurred on soils ranging in texture from sandy loam to silty clay loam and soil organic matter concentrations from ~1 to 3%. Yield increases with S fertilization were not predicted by Mehlich‑3... J. Camberato, D. Salguero, R. Nielsen |
