Soil Conservation Techniques and Concepts

The video tutorial introduces contour and terrace farming, focusing on their roles in preventing soil erosion. It explains soil erosion and its prevention methods, such as afforestation and specific farming techniques. Terrace farming involves cutting wide steps on hill slopes to retain water and prevent soil erosion, commonly practiced in Asian countries. Contour ploughing follows the natural slope of the land, using contour lines to prevent soil erosion by acting as water breaks.
