Question

Write in detail of any two methods of soil conservation

Answer 1

∆∆∆ CROP ROTATION
Cover crops such as legumes, white turnip, radishes and other species are rotated with cash crops to blanket the soil year-round and act as green manure that replenishes nitrogen and other critical nutrients.they help in nitrogen fixation of the soil and replenishing its fertility as the rhizome bacteria in their root nodules which help in atmospheric nitrogen fixation and hence makes the soil fertile even after repetitive farming and hence helps in soil conservation

∆∆∆ TERRACE FARMING
this method of farming is used in Hilly regions where there are steep slopes. these slopes are cut down to reduce urban runoff as these runoff or perennial rivers wash away the soil making it barren and susceptible to erosion and landslides in Hilly regions. instead when we cut the slopes for farming the plant roots bind the soil well and also prevent washing away.
hope it helped
if u lyk my answer then pls follow me n mark as brainiest I'll be there to hep

Answer 2

Hello!!
Heres ur answer!! The methods are:
1)Afforestation:
The best way to conserve soil is to increase area under forests. Indiscriminate felling of trees should be stopped and efforts should be made to plant trees in new areas. A minimum area of forest land for the whole country that is considered healthy for soil and water conservation is between 20 to 25 per cent but it was raised to 33 per cent in the second five year plan; the proportion being 20 per cent for the plains and 60 per cent for hilly and mountainous regions.
2. Checking Overgrazing:
Overgrazing of forests and grass lands by animals, especially by goats and sheep, should be properly checked. Separate grazing grounds should be earmarked and fodder crops should be grown in larger quantities. Animals freely move about in the fields for grazing and spoil the soil by their hoofs which leads to soil erosion. This should be avoided.
