Webcontour plowing advantages and disadvantages. These objectives are achieved by means of furrows, crop rows, and wheel tracks across slopes, all of which act as reservoirs to catch and retain rainwater, thus permitting increased infiltration and more uniform distribution of the water. When water reaches the weaker soil that lacks the minerals needed to make it stronger, it normally washes it away. hVNAAw#HQ_@mT Contour farming is most effective when used in conjunction with such practices as strip cropping, terracing, and water diversion. Inter-crops maintain the soil fertility as the nutrient uptake is made from both layers of soil. Slugs, earwigs, cutworms, and other pests love cool, dark, moist places. Reducing erosion and preventing habitat destruction. The Farming across the slope helps to shorten slope lengths, slowing down runoff water so it can soak into the soil. Contour farming slows water down and lets it soak into the soil. 2 Combine contour farming with cover cropping and other conservation practices for more soil fertility and slope protection.
