| Abstract | This chapter intended to examine the interplay among biomass production, land management, and conservation practices and their impact(s) on water quality and hydrology. The study evaluated proposed future biomass production under partial land use change, crop residue harvest, and conservation practices in a Corn Belt watershed using SWAT model, followed by a temporal analysis. Results showed that installing riparian buffer in the entire stream network in the watershed could deliver a strong performance in reducing loss of sediments (62%) and phosphorus (30%) and have the lowest impact on stream flow (1%) among the four scenarios despite its small reduction in nitrate levels (5%). Partial land conversion to grow SWG along with residue harvest and cover crop could receive the highest nitrate loading reduction (26%) and performed well especially in high flow years, whereas it decreased annual stream flow by 13% on 20 year average. Switchgrass could contribute to changes in evapotranspiration and the distribution among surface runoff, lateral flow, groundwater flow, and tile drain flow. Our analysis indicates the benefits of incorporating conservation practices into land use planning with the consideration of regional distinct landscape, soil, climate, and crop conditions. |
