Strip tillage and cover cropping for enhanced water use efficiency in western Washington organic vegetable farms

Tillage is an important tool in organic systems for weed control, residue management, seedbed preparation, and regulation of spring soil temperature. As excessive tillage wastes energy and degrades soil quality, organic producers are encouraged to reduce tillage. Soil water also evaporates more quickly from bare, tilled soils, potentially increasing irrigation demand. This integrated research and […]
