(2) require observance of particular methods of cultivation, including:

(A) contour cultivating, contour furrowing, lister furrowing, or strip cropping;

(B) planting, sowing, or seeding land with water-conserving and erosion-preventing plants, trees, or grasses; and

(C) forestations and reforestations;

(3) specify cropping programs and tillage practices to be observed;

(4) require the retirement from cultivation of highly erosive areas or of areas on which erosion may not be adequately controlled if cultivation is carried on; or
