The most economical method of soil conservation is to: Correct Answer afforest the area

Afforestation means planting trees. As we know, the roots of the trees help to hold the soil layer firmly, it is evident that it helps not to make the soil loose and prevents erosion.

Thus by planting more and more trees, the top layer of the soil becomes less prone to erosion by wind, water etc. Hence it prevents erosion and helps in soil conservation.

Note: Contour bunds and check bunds are basically water harvesting techniques.
