1. Tillage and Nitrogen Rates Influenced Wheat and Sorghum Productivity Reduced tillage (RT) or no-tillage (NT) practices and reducing fallow frequency can both decrease soil losses from wind erosion and conserve soil water in the semiarid regions of the US Great Plains. This study evaluated sorghum grain yield in 2013 and wheat grain yield in 2014 and 2015 as influenced by long-term nitrogen (N) fertilizer application rates (0, 20, 40, and 60 lb N ac- 1) and tillage intensity [clean tillage (CT), RT, and NT] in dryland winter wheat–sorghum-fallow (W-S-F) cropping...

2. Influence of Nitrogen Rate Application on Soil Fertility in Four Long Term Experiments Sites Total organic carbon (TOC) and total nitrogen (TN) are the most important components of the soil as they are key indicators of its quality and productivity. Nitrogen fertilization is an effective management practice for improving and maintaining soil fertility and enhancing crop productivity. The objective of this study is to determine the effect of different Nitrogen rate application on SOC and TN. This study was carried out in four separate long-term sites across Oklahoma State, established... M. Maatougui, B. Arnall Download paper
