There are several ways possible for soil conservation. They are planting trees, terraces, no-till farming, contour ploughing, crop rotation, soil pH, watering the soil, salinity management, soil organisms and indigenous crops.
1. Planting trees :
a) Soil that is under a vegetative cover has hardly any chance of getting eroded as the vegetative cover acts as a wind barrier.
b) As the roots of the trees spread deep into the layers of soil they contribute to the prevention of soil erosion.
2. Terraces :
a) A terrace is a leveled section of hilly cultivated area.
b) Owing to its unique structure, it prevents the rapid surface runoff of water.
3. No-till farming : It is a way of growing crops without disturbing it through tillage.
4. Contour ploughing :
a) It is the method of ploughing across the contour lines of a slope.
b) This method helps in slowing the water runoff and prevents the soil from being washed away along the slope.
5. Crop rotation: Crop rotation helps in the improvement of soil structure and fertility.
6. Soil pH : Maintenance of the most suitable value of pH is essential for the conservation of soil.
7. Water the soil : Watering the soil along with the plants is a way to prevent soil erosion caused by wind.
8. Salinity management :
a) If salinity of the soil increases it results in the death of vegetation.
b) The death of vegetation is bound to cause soil erosion.
c) Hence salinity management is one of the indirect ways to conserve soil.
9. Soil organisms : The helpful organisms of soil promote its fertility and form an element in the conservation of soil.
10. Indigenous crops : Planting of native crops is known to be beneficial for soil conservation.
