Which of the following is a Bio-logical method of soil conservations? (1) Contour fanning (2) Contour terracing (3) Gully control (4) Basin listing

1 Answer

Answer :

(1) Contour fanning Explanation: The biological methods of soil conservation include contour farming, strip cropping, tillage operation, mulching, etc. Contour farming is practiced in the hilly regions or on the slopes. The contours (circular or peripheral furrows) catch the downwardly moving water until it is absorbed in the soil. It reduces run off, saves more water for crops, and reduces soil erosion.
