The method which is used for soil conservation is Crop Rotation, Contour Ploughing, and Improving Agricultural Practices.
This includes growing different types of crops in the same geographical field and exchanging them with other crops in the same order over a period of time. This practice prevents overconsumption of certain nutrients in the soil. Rotations occur on average of every 3-4 years.
Contour ploughing is the practice of plowing and planting trees along the slope of a geographic area, followed by the elevation contours of that area. It reduces soil erosion, promotes water infiltration, and reduces sediment runoff. It also maintains the quality and composition of the soil.
Improving Agricultural Practices
Terrace farming prevents the flow of water by removing minerals from the soil by slowing its speed and correcting the direction of its flow whereas Plant windbreaks such as trees or bushes are used to prevent unnecessary wind from blowing off the soil.
