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. Preserving the Past, Nurturing the Future: Inorganic Fertilizers and the Vital Role of Phosphorus and Potassium in Native Prairie RestorationPhosphorus (P) and potassium (K) are macronutrients required to sustain plant growth and reproduction. They are commonly applied as inorganic fertilizer by farmers across the world for their crops but these nutrients are also important for the development and sustainment of native grassland systems. Much of the Great Plains region has either been used as farmland or grazing land. These practices can disturb natural nutrient cycling by removing nutrients without adequate replacement. Current literature... K. Hays, B. Arnall |
