Assessing winter cover crop nutrient uptake efficiency using a water quality simulation model by I.-Y. Yeo, S. Lee, A. M. Sadeghi, P. C. Beeson, W. D. Hively, G. W. McCarty, M. W. Lang

“…A physically based watershed simulation model, Soil and Water Assessment Tool (SWAT), was calibrated and validated using water quality monitoring data to simulate hydrological processes and agricultural nutrient cycling over the period of 1990–2000. To accurately simulate winter cover crop biomass in relation to growing conditions, a new approach was developed to further calibrate plant growth parameters that control the leaf area development curve using multitemporal satellite-based measurements of species-specific winter cover crop performance. …”
