Grass hedges are inexpensive vegetative barriers that can slow runoff and help control concentrated flow erosion. Terraces, waterways, and grass hedges can complement conservation tillage to provide a comprehensive runoff and erosion control system. Ongoing research seeks to optimize the combination of these practices in the most economical and effective manner for variable landscapes. These research findings show that several conservation management systems are capable of keeping soil losses below tolerance limits for row-crops on fields with steepnesses and lengths typical of those on DEC watersheds.
