Question

Which among the following is a good method to slow down water run off in slopes? a)Mulching B)Shelter belts c)Terrace Farming d) Roof water collection

Answer 1

Answer:

c)Terrace Farming

Explanation:

Terrace farming is the method of growing crops on sides of hills, mountains

and steep slopes by planting on graduated terraces built into the slope. Though, the terrace cultivation is labour intensive but this method has been employed effectively to maximize arable land area in variable terrains and to reduce soil erosion and water loss. In most of the systems the terrace is low, flat ridge of earth built across the slope, with a channel for runoff water just above the ridge. Usually, terraces are built on a straight grade so that the water caught in the channel moves slowly toward the terrace outlet. In areas where soils are able to take in water readily and rainfall is relatively low, level terraces may be used.
