Plowing across hill slopes

Explanation:

The process of plowing along the land slopes is called contour plowing. The method is essential in creating furrows and crop rows which reserves rainwater. The process, therefore, preserves erosion which has been destroyed for years according to the research of the federal program.

The commission also taught framers on the importance of practicing plowing to preserve the soil by ensuring farmers use the methods of conserving the soil. This was achievable through active agricultural programs that the government established to farmers.
