Answer 2

Answer:

(i) Contour Farming:

Contour farming may be defined as ploughing, seeding, cultivating and harvesting across the slope, rather than with it.

(ii) Strip Cropping:

On land with a decided slope, planting crops on contour strips will be an effective erosion determent. For effective control the width of the contour strip should vary inversely with the length of the slope. Strip cropping should be combined with crop rotation, so that a strip planted to a soil depleting, erosion-facilitating corn crop one year will be sown to a soil enriching and protecting strip of legumes the next.

(iii) Terracing:

The practice of terracing has been common in ancient China. The flat, step-like bench terraces are now not useful. The modern terrace is an embankment of earth constructed across a slope in such a way as to control water run-off and minimise erosion. To be effective, terrace must check water flow before it attains sufficient velocity to loosen and transport soil.

(iv) Gully Reclamation:

Gullies are danger signals that indicate land is eroding rapidly and may become a wasteland as in the case of vast areas along the rivers Chambal and Yamuna. If a gully is small it may be ploughed in and then seeded to quick-growing crops like barley, maize, jowar, wheat in order to check erosion.

(v) Shelter Belts:

These are the ‘green belts’ of trees which help to break the force of strong winds and thus, prevent or cut to a minimum the blowing away of the loose top-soil. In areas where wind erosion is more, rows of trees may be helpful to check the flow of winds. Apart from this, these trees will also add colour to the landscape and help to control the desert spread.
