How can you check soil erosion?
Describe any two methods in detail.
Answers
Answer:
Ploughing along the contour lines can decelerate the flow of water down the slopes. This is called contour ploughing.
Steps can be cut out on the slopes making terraces. Terrace cultivation restricts erosion.
Large fields can be divided into strips. Strips of grass are left to grow between the crops.
Answer:
The following measures can be taken to prevent soil erosion and ensure soil conservation:
Terrace Farming - On hilly slopes, terraces act as bunds and prevent the soil from being washed away by running water. Terrace farming is practiced with successful results in Japan, South-East Asia and the USA.
Contour Ploughing - Ploughing along contours on a slope prevents soil being washed away by rains or by surface run off. Contours act like bunds. Terraces are leveled into step-like small fields with even slopes. Contour ploughing is common in countries like Japan, China and some of the South-East Asian countries.
