D) The sounds frequency increases. To accumulate moisture in these dry areas, cropland is periodically left fallow. Inter-crops maintain the soil fertility as the nutrient uptake is made from both layers of soil. Encyclopaedia Britannica's editors oversee subject areas in which they have extensive knowledge, whether from years of experience gained by working on that content or via study for an advanced degree.

How do contour plowing and no-till farming help make agriculture more sustainable? One major disadvantage of terracing is rainwater saturation of the ground. contour farming, the practice of tilling sloped land along lines of consistent elevation in order to conserve rainwater and to reduce soil losses from surface erosion. Soil erosion prevention practices such as this can drastically decrease negative effects associated with soil erosion such as The practice has been proved to reduce fertilizer loss, power and time consumption, and wear on machines, as well as to increase crop yields and reduce erosion. Let us know if you have suggestions to improve this article (requires login). Although in the United States the technique was first practiced at the turn of the 19th century, straight-line planting in rows parallel to field boundaries and regardless of slopes long remained the prevalent method.
