Response Of Soil Properties To 23-25 Years Of Diverse Crop Rotations And Tillage Systems In South Dakota, Usa, Abdullah H. Alhameid

Electronic Theses and Dissertations

Diverse cropping systems and no-till (NT) are beneficial in improving soil organic carbon (SOC) and other soils properties. The present study was conducted to evaluate the interactions and impacts of long-term tillage and diverse crop rotation systems on soil quality indicators that include a range of soil chemical, physical, hydrological, and microbial properties. The study was established in 1991 at Beresford, South Dakota and included three crop rotation systems [2-yr; maize (Zea mays L.)-soybean (Glycine max L.), 3-yr; maize-soybean-oat (Avena sativa L.), and 4-yr; maize-soybean-oat-wheat (Triticum aestivum L.)] managed under two tillage systems (NT and CT; conventional- tillage). Soil sampling …


Long-Term Impacts Of Annual Cattle Manure And Fertilizer On Soil Quality Under Corn-Soybean Rotation In Eastern South Dakota, Ekrem Ozlu Jan 2016

Long-Term Impacts Of Annual Cattle Manure And Fertilizer On Soil Quality Under Corn-Soybean Rotation In Eastern South Dakota, Ekrem Ozlu

Electronic Theses and Dissertations

Dairy and beef manure have been used to enhance soil quality; however, their impacts under long-term application in corn-soybean rotation need to be evaluated. Nutrient based recommended rates of manure applications on soils are important and also need to be monitored. This study, therefore, was conducted at two long-term sites to assess the impacts of manure and inorganic fertilizer application rates on some of the soil quality indicators and greenhouse gas emissions (GHGs) in a corn (Zea mays L.) - soybean (Glycine max L.) rotation system located at Beresford and Brookings in Eastern South Dakota. Study treatments included: …
