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. Forages and Livestock to Diversify Wheat-based Cropping SystemIntegrating annual forages and ruminant livestock to intensify dryland cropping systems have the potential to increase profitability, increase water use efficiency, and improve soil health. The objective of this study was to determine the crop yield and soil property impacts of intensifying traditional no-till winter wheat (Triticum aestivum L.)-grain sorghum (Sorghum bicolor Moench)-fallow (W-GS-F) with annual forages as well as integrating livestock. This study was initiated... Z. Carson, A. Obour, J. Holman, K. Roozeboom |
