Short summary

This study demonstrates the effectiveness of winter cover crops for reducing nitrate loads using the Soil and Water Assessment Tool (SWAT). It illustrates the following: (1) nitrate removal efficiency varies greatly by species, timing, and extent of winter cover crop implementation; and (2) nitrate exports vary based on edaphic and agronomic characteristics of the croplands upon which crops are planted.
