Question

explan mulching and contour bunding;;;;;;;;

Answer 1

Hi,

Mulching- The bare ground between plants is covered with a layer of organic matter like straw or peat to prevent loss of moisture from the soil. This process of conserving soil by retaining the moisture in the soil is called mulching.

----------------------------

Contour bunding- On hill sides, stone are used to build barriers across the slope, following contours. Contours are imaginary lines connecting places that lie at the same altitude. Trenches are made in front of the barriers to collect water. This way of preventing soil erosion is called contour barrier or contour bunding.
