Contour hedgerows of alfalfa in annual cropland [阿富汗]
Hedgerows are vegetative strips of perennial grasses, shrubs or legumes - such as alfalfa - located along contours across a slope. These vegetative strips form a barrier to halt soil erosion and improve soil fertility. Hedgerows of alfalfa also provide quality animal fodder for a period of 5-10 years.
