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. Phosphorus Fertilizer Management and Cover Crop Effects on Phosphorus Loss from No-till Corn and Soybean. Loss of phosphorus from non-point source agricultural sources is a known contributor to the degradation and contamination of surface waters. Therefore, it is imperative to adapt agricultural best management practices which promote and preserve surface water quality. The goal of this study was to quantify the impacts of phosphorus fertilizer management practice (placement and timing) and winter cover crop on concentrations of total suspended solids, total phosphorus, and dissolved reactive phosphorus...

3. Optimizing Irrigation and Fertilizer Management in Cotton to Increase Nitrogen Use Efficiency Nitrogen (N) fertilizer is an important nutrient in cotton production, and if the optimal amount is not applied yield penalty may occur (Hutmacher et al. 2004). A more efficient application of N fertilizer based on plant N requirements, soil texture, and N availability can increase cotton yield and N-use efficiency (NUE). The main objective of this research was to determine the relationship between cotton lint yield and normalized difference vegetation index (NDVI) across multiple irrigation levels,... A.

4. Relationship Between Plant Nitrogen and NDVI of Cotton on the Texas High Plains Nitrogen (N) is one of the most limiting factors in Texas High Plains cotton production (Bronson et al., 2001). Nitrogen build-up in cotton is near maximum for the season at first open boll, when leaf senescence begins (Li et al., 2001). Lint yield response to N is difficult to predict due to N response relying on water management and initial soil nitrate (NO3--N) (Morrow and Krieg, 1990). Normalized difference vegetative index (NDVI) is a tool that has been used to manage... A. Bumguardner, K. Lewis, G. Ritchie, K. Bronson, M. Maeda Download paper
