A similar practice is contour bunding where stones are placed around the contours of slopes. La culture en courbes de niveau, (en anglais, contour plowing ou contour farming ou contour ploughing) est la pratique agricole consistant à labourer et/ou à planter sur une pente. jw2019 The administration also began to educate farmers on soil conservation and anti-erosion techniques, including crop rotation, strip farming, contour plowing, terracing, and other.
