1. 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...

2. The Effects of Manure Applications on Cotton Yield and Soil Greenhouse Gas Emissions in the Texas High PlainsThe cost of inorganic fertilizer is continually rising, which has caused an increased interest in alternative solutions. Along with fertilizer prices increasing, carbon emissions are following the same trend. There is an upcoming demand for organic fertilizer and carbon research. The purpose of this study was to assess the effects of various manure applications on crop growth and greenhouse gas emissions in three different cropping systems in the Texas High Plains. The no-tillage cropping systems... T. Roberts, K. Lewis |
