At the very beginning of the formation, you can fill up the ravine.

If the ravine is so large that it cannot be filled in, it is completely planted with trees and shrubs.

This stops the growth of the ravine and gives a person new forest lands.

Where there is a lack of water in the soil, droughts often occur, the earth is threatened by wind erosion.

Different methods of land cultivation have been developed for different sites.

For example, mulching stubble during non-fallow plowing.

When cultivating the soil, stubble is preserved, which will protect the land from wind, rain and meltwater.

Forest planting on the edge of the field, a wall of backstage crops, stubble reduce wind speed and delay snow in the fields.

Snow melts slowly on the prepared field and is absorbed into the soil.

The grain sprouts in the ground.
