Question

Farmers who have hilly land cultivate according to the curves of the land in order to prevent ?

Answer 1

Answer: Erosion.

Explanation:

The farmers of the Midwest realize that the good soil is a precious natural resource. Where the land is more hilly, farmers plow following the curve of the hill instead of up and down. If the rows of crops went up and down the hill, rain would wash quickly along the furrows. Soil, and perhaps the crop itself, would be washed away. Washing away of soil is called erosion. If the rows of crops go around the hill, the water is stopped by each row and soaks into the soil.

Answer 2

Soil losses

The farmers with hilly land cultivate crops on slope land along lines of consistent elevation or contour (known as contour farming) for two main reasons

a) To conserve rainwater

b) To reduce soil losses from surface erosion
