hello friend,
ur answer is :
1.Contour ploughing: Contour ploughing orients crop furrows following the contour lines of the farmed area. Furrows move left and right to maintain a constant altitude, which reduces runoff. Contour plowing was practiced by the ancient Phoenicians, and is effective for slopes between two and ten percent. Contour plowing can increase crop yields from 10 to 50 percent, partially as a result of greater soil retention
2.Terrace Farming: Terracing is the practice of creating nearly level areas in a hillside area. The terraces form a series of steps, each at a higher level than the previous. Terraces are protected from erosion by other soil barriers.
3.Keyline design: is an enhancement of contour farming, where the total watershed properties are taken into account in forming the contour lines.
i hope it helps u
