Use of best management practices in recent years has reduced these off-site impacts, especially for sediments. We evaluated a combination of best management practices on two agricultural Piedmont watersheds in North Carolina to estimate the combined reductions that can be achieved for tobacco cultivation. We evaluated the effectiveness of three best management practices for flue-cured tobacco production—reduced-till versus conventional tillage, grassed field-side filter zones, and forested filter zones—to determine the total reduction in suspended solids from storm runoff. Use of reduced tillage alone reduced total suspended solids (mostly sediment) leaving tobacco fields by 82%. The grassed filter zones at field edge functioned very well in retaining solids in early summer but were overloaded with sediment by late summer after summer thunderstorms and reduced grass growth due to high summer temperatures of cool-season grasses. However, the down-slope forested filter zones were able to back up the grassed filter zones when they overloaded and exported sediment to the forested zones. In combination, grassed and forested filters retained 68% to 69% of suspended solids. One forested filter zone had recently been cutover following hurricane damage.

Dense vegetation in the cutover forested filter zone more than doubled its capacity to detain solids, compared to the same forested filter zone when it was covered by mature mixed pine-hardwood.
