Preliminary Effects of Crop Residue Management on Soil Quality and Crop Production under Different Soil Management Regimes in Corn-Wheat Rotation Systems

Strategic management of crop residues is essential to enhance soil quality for sustainable agriculture. However, little known about the specific amounts needed improve characteristics which are key develop economic plans. In this study, we investigated effects applying residue at five rates, including 100% (R100), 75% (R75), 50% (R50), 25% (R25), and 0% (R0), on wheat yield properties. Field experiments were conducted two cropping seasons in a wheat-corn rotation under conventional (CT) no-till (NT) systems observe first results obtained during short-term periods (one-year application). During corn fields irrigated. Application plant resulted increased organic carbon (SOC) available nutrients improved physical properties, i.e., aggregates mean weight diameter wet (MWDw) dry (MWDd) conditions, water-stable (WSA), dry-stable aggregates, (DSA), water infiltration (SWI), (SAW), corn. The stronger higher application rates. CT system, compared R0, R100 highest increase equal 38, 29, 23, 34, 35, 41, 11% SOC, MWDw, MWDd, WSA, DSA, SAW, grain yield, respectively. This was equivalent 28, 19.5, 19, 37, 44, 52, 6% NT Generally, system stratification properties within 0–10 cm 10–20 depth, but uniform distribution both depths system. Overall, these show that can cereal production semi-arid conditions year application. It will be monitor changes along-term field studies.
