Some advantages of contour plowing is that it focuses on preserving topsoil by reducing erosion from water runoff. What are the goals of sustainable agriculture? How does contour plowing conserve soil? Contour plowing/ploughing conserves soil by following the lay of the land and creating ridges that form a water break to prevent soil erosion. Furrows that do not follow the lay of the land cause rapid runoff during rainfall by forming a convenient channel for the water to flow downhill. (2) Pams erythrocyte count was increasing.
