Question

what is soil erosion conservation ? Explain any three methods of soil conservayion

Answer 1

Soil conservation is the preventing of soil loss from erosion or reduced fertility caused by over usage, acidification, salinization or other chemical soil contamination. Slash-and-burn and other unsustainable methods of subsistence farming are practiced in some lesser developed areas.

Answer 2

hey..mate here's yur ans..

Soil conservation is the preventing of soil loss from erosion or reduced fertility caused by over usage, acidification, salinization or other chemical soil contamination

methods for soil conversion are..

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.

Terraced farming is more common on small farms and in underdeveloped countries, since mechanized equipment is difficult to deploy in this setting. It protects the soil from its erosion. It is one of the way by which soil erosion can be stopped

3)Keyline design.

Keyline design is an enhancement of contour farming, where the total watershed properties are taken into account in forming the contour lines.
