Explain the process and purpose of strip cropping

Strip cropping is the process by which strips of different crops are grown across the contour.

Explanation:

For instance,

Corn grown in a strip along the contour can have an alternate strip of beans.

Strip cropping has the purpose of preventing soil erosion.

This is achieved when water flowing down the contour slows down its speed due to the blocking strips of crops.

The strips also trap any eroded soil particles flowing down slope with water.

weathering is the answer.
