Integration of Sorghum as a Biofuel Species into Cropping Systems for the Southeastern U.S. (PPT)

摘要

1. Blue Lupine, Gahaba Vetch and Austrian Pea perform "best" in this cropping system, while Faba Bean and Crimson Clover offered minimal benefit to the system. 2. Highest yields produced by Blue Lupine and Sorghum grown after Blue Lupine and Cahaba Vetch, which also reduces nematodes. 3. A roiled winter legume crop has greater carry-over benefit to both Cotton and Sorghum yields, weed control and soil quality. Soil Science: 4. Over repeated cropping cycles some winter legumes appear to have an increasing benefit to soil quality and subsequent summer crop yields 5. Blue Lupine returned more nitrogen to the soil, and along with Cahaba Vetch and Austrian imparted more nitrogen to the Sorghum Crop Entomology: 6. A refugia of "Banker Plants" particularly Blue Lupine and Cahaba Vetch is really only helpful in the Cotton Crop, not in Sorghum.
