• Some soil conservation methods  
  • Mulching
    • A layer of organic matter like straw covers the bare ground between plants and helps to maintain soil moisture.
  • Contour barriers
    • To create barriers along contours, stones, grass, the soil is being used.
    • Trenches are made to collect water in front of the barriers.
  • Rock dam
    • Rocks are stacked up to slow down water flow and also help to stop gullies and further erosion of soil.
  • Terrace farming
    • On the steep slopes, wide flat steps or terraces are designed so that flat surfaces are used for cultivation.
    • Thus minimizing surface run-off and soil erosion.
  • Intercropping
    • Various crops can be grown in alternating rows and are planted at varying times to protect the soil from rain washing.
  • Ploughing of contours
    • Ploughing parallel to the contours of a hill slope to create a natural obstacle for fluid to drain down the slope.
  • Shelterbelts
    • In the coastal and dry areas, rows of trees are cultivated to track the passage of air and preserve the cover of the soil.
