| Abstract: | In this study, the authors investigate the impacts of incorporating solid dairy waste on fields double-cropped with sorghum and winter-wheat, based on simulations performed for the upper North Bosque Watershed located in north central Texas. The effects of incorporation were evaluated at three different manure application rates. On aggregate across all three manure application rates, significant declines in P losses were obtained with incorporation except for sediment-bound P losses under the N-based manure application rate scenario. The authors found that the practice of incorporating manure shortly after it has been broadcast on the soil surface could help reduce P losses in such situations where P- based rates alone prove inadequate. |
