1. Cover Crop Impacts on Corn and Soybean Nitrogen Accumulation and YieldThe need to retain soil N between economic crops has renewed interest in cover crops for the eastern cornbelt but their management remains a barrier to widespread adoption. We conducted a 3 site-yr study to determine effects of cover species (wheat or rye) and biomass management (burndown 40 d, 20 d, or 2 d preplant) on corn and soybean yields. Sites included a very poorly drained (wland wlo tile drainage) and a well drained silt loam. With adequate drainage, cover biomass 40 d preplant averaged... |
2. Effect of Liquid Calcium as a Liming Agent in SoilMaintaining proper soil pH is the foundation of a soil fertility program and influences plant productivity, nutrient availability, and herbicide activity. This study was conducted to determine the effectiveness of liquid calcium compared to known liming agents to raise the pH of soil. Test plots that compare liquid calcium to proven liming agents were conducted in 17 counties across the state of Kentucky on cool season annual grass pastures. Two experimental protocols were developed... B. Setchell, E. Ritchey |
