soil erosionCrist any four methods of chellingand improving soil fertility? |
|
Answer» Various methods of checking soil erosion are Strip cropping, Terrace farming, Contour ploughing Soil erosion can be prevented by strip cropping, i.e. by growing different crops on the same field in different strips. Terrace Farming is another common method that involves cutting down mountain slopes in small terraces to prevent washing away of soil. Another common method is contour ploughing, that involves ploughing around contours of the slope to prevent erosion. Soil fertility is the ability of soil to sustain plant growth and optimize crop yield. This can be enhanced through organic and inorganic fertilizers to the soil. Nuclear techniques provide data that enhances soil fertility and crop production while minimizing the environmental impact. |
