In many parts of southern Africa dry, windy weather occurs in winter when the soil is barren. To reduce loss of soil by wind, hedges or windbreaks are planted between arable strips to lessen its force. In some cases winter crops or fodder are grown to help keep the soil in place. The addition of lime causes adhesion of soil particles and also prevents or reduces the loss of soil.

Plants play an important role in keeping this erosion process under control. They tend to hold the soil in place and prevent rainwater from carrying the soil away. The plants trap the water so that it gradually seeps into the ground. Plants also help to contribute to the formation of soil, as their roots are constantly prying rocks apart, helping to grind them up into smaller fragments.
