What do grape growers do to stop soil erosion?
A. It is very much in vineyardists’ interest to preserve topsoil. Grapegrowers use mulch and plant cover crops to stop erosion in newvineyards, and many vineyards have permanent cover crops to reduce bothdust and erosion. The Vineyard Erosion and Sedimentation ControlOrdinance (VESCO) requires growers to submit erosion control plans forall new vineyards with greater than 10 or 15% slope.
