What is the difference between soil erosion and soil conservation?

Answer 1

• 1. Soil Erosion and Soil Conservation
• 2. What is soil erosion? The denudation of the soil cover and subsequent washing down is described as soil erosion. There are two causes of Soil erosion Natural Factors. Human Factors. Soil erosion by running water Soil erosion by wind
• 3. Human factor in soil erosion Match the given photos with appropriate factor Deforestation, Over-grazing, Construction activities, Mining activities. Defective methods of farming such as ploughing in a wrong way i.e. up and down the slope.
• 4. Types of soil erosion Gullies : The running water cuts through the clayey soils and makes deep channels as gullies. Badlands: The land becomes unfit for cultivation and is known as bad land. Ravines: In the Chambal basin such lands are called ravines. Ravines of Chambal basin Badlands Rills and gully erosion
• 5. Types of soil erosion Sheet Erosion : Sometimes water flows as a sheet over large areas down a slope. In such cases the top soil is washed away. This is known as sheet erosion. Wind erosion: Wind blows loose soil off flat or sloping land known as wind erosion .
• 6. Methods of Soil conservation Contour Ploughing : Ploughing along the contour lines can decelerate the flow of water down the slopes. Terrace Farming : Steps can be cut out on the slopes making terraces. Terrace cultivation restricts erosion. Western and central Himalayas have well developed terrace farming. Carefully observe the difference between the two.
• 7. Methods of Soil conservation Strip Farming : Large fields can be divided into strips. Strips of grass are left to grow between the crops. This breaks up the force of the wind. Shelter Belts : Planting lines of trees to create shelter also works in a similar way. Rows of such trees are called shelter belts. These shelter belts have contributed significantly to the stabilisation of sand dunes and in stabilising the desert in western India. Observe the trees in the background. Why are they planted there? Can you see the Strips?

Answer 2

Soil erosion is the natural process of soil being removed from one location and deposited elsewhere, often due to water or wind. Soil conservation refers to the practices and techniques used to prevent or minimize soil erosion, such as contour plowing, terracing, cover cropping, and planting trees. In essence, soil erosion describes the problem, while soil conservation describes the solution.
