Answer:
Explanation:
Soil erosion is a naturally occurring process that affects all landforms. In agriculture, soil erosion refers to the wearing away of a field's topsoil by the natural physical forces of water and wind or through forces associated with farming activities such as tillage.
plantation of trees are the most helpful step to stop soil erosion.
Answer:
Soil erosion is the displacement of the upper layer of soil, it is one form of soil degradation.
The following are five important measures taken to prevent soil erosion and ensure soil conservation:
1. 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.
2. Shelter Belts - Peasants plant trees in several rows to reduce wind erosion. They are called ‘wind breaks’.
3. 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.
4. Strip Cropping - In this system, crops are grown in alternate strips of land in order to check the effect of the winds.
5. Construction of Dams - Rivers are known to cause soil erosion. Dams are built in the upper course of the rivers in order to control the erosion of soil.
