Which method is used to prevent soil erosion on hills?

Which method is used to prevent soil erosion on hills?

Contour Ploughing
Contour Ploughing: If ploughing done at right angles to the hill slope, following the natural contours of the hill, the ridges and furrows break the flow of water down the hill. This will prevents soil erosion.

How can hilly areas detect soil erosion?

Explanation: In hilly areas, soil erosion can be controlled by ploughing across countour lines, making use of terrace farming techniques and using strips of grasses to check soil erosion by wind and water.

Which one of the following methods is the most appropriate to check soil erosion in the coastal regions?

The correct answer of this question is option (c) terrace cultivation. and steep slopes by planting on graduated terraces built into the slope.

What is the best way to prevent gully erosion in hilly areas?

Following steps are taken to control the soil erosion in hilly areas: (i) Contour ploughing: this refers to ploughing along contour lines. (ii) Terrace farming: construction of steps along the hilly areas by cutting the rock layers to reduce the flow of rivers. (iii) Plugging of gullies to prevent gully erosion.

What are the two important agents of soil erosion?

The agents of soil erosion are the same as the agents of all types of erosion: water, wind, ice, or gravity. Running water is the leading cause of soil erosion, because water is abundant and has a lot of power. Wind is also a leading cause of soil erosion because wind can pick up soil and blow it far away.

Which of the following is not a method for checking soil erosion?

Complete answer: Overgrazing is the method which is not involved in soil conservation. Soil conservation is the process of preventing soil erosion and to stop the soil from becoming infertile.

What type of erosion causes desertification?

soil erosion
Answer: A major consideration in desertification is soil erosion. It transforms inhabitable areas into deserts.

What is soil erosion mention two steps that could be taken to prevent soil erosion?

Two ways to prevent soil erosion are: Shelter belts: Trees should be planted in several rows to check the speed of the wind. This reduces soil erosion because of wind. Constructing dams: Because the rivers cause soil pollution, dams are built in the upper course of the rivers to check soil erosion.

What is the formation of soil called?

pedogenesis
The soil formation process is termed ‘pedogenesis’. Climatic conditions are important factors affecting both the form and rate of physical and chemical weathering of the parent material.

What are the two methods of checking soil erosion?

Strip cropping, Contour ploughing, Use of irrigation and fertilisers and Terrace farming are methods of checking soil erosion.

What are the methods used for checking soil erosion?

Contour ploughing,building terraces that intercept and stop downward movement of soil. Netting is a temporary form of erosion control. Maintaining plant cover reduces wind speed. Growing crops in intervals across a field of cereals,and using trees and shrubs as shelter belts or wind breaks are also helpful.

Which method is used for checking soil erosion?

What are three ways to prevent erosion on a steep hillside?

What Is Done to Reduce Soil Erosion on Steep Slopes?

1. Planting and Watering. Improved planting and watering practices reduce soil erosion on steep slopes.
2. Controling Soil. Heavy rain washes away bare soil on steep slopes, but soil amendments and mulches reduce soil loss.
3. Growing Ground Cover Plants.
4. Building Terraces.

How can we check soil erosion by agronomic method?

Widely used agronomic measures for water erosion control are listed below. Contour Cropping is a conservation farming method that is used on slopes to control soil losses due to water erosion. Contour cropping involves planting crops across the slope instead of up and down the slope (Fig. 4.1).

Where is gully erosion commonly found?

> Gully Erosion is most commonly found in the states of Uttar Pradesh, Madhya Pradesh, Gujrat, West Bengal and Rajasthan.

Which are the two main factors responsible for soil formation?

ANS-Temperature and rainfall are the two main climatic factors responsible for soil formation.

How to prevent soil erosion on steep slopes?

Another option for erosion control on steep slopes is a series of rolled up logs or “wattles” made from fibrous material (like straw). Water running down the slope will slow down when it hits the logs, soaking into the soil instead of carrying mud downhill.

What can I do to keep my slope from eroding?

Building a retaining wall or a terrace are standard measures for keeping slopes in check. They hold soil in place and channel water to prevent soil erosion. Growing ornamental grasses, wildflowers, native plants, and shrubs are other ways to stop soil from eroding.

Why is there so much erosion on my hill?

Run-off from heavy spring or summer rainfall is not the only face of erosion — wind can just as easily blow soil particles down a slope. If your hill gets a lot of sun exposure, evaporation can quickly degrade its quality. To guard against these slow but sure soil eroders, you can use a combination of these five techniques.

How can you control erosion on an embankment?

You could also control erosion by controlling the soil itself. As heavy rain tends to be the biggest culprit for soil erosion on slopes and embankments, by controlling the composition of the soil, you could control the effect that water has on it and therefore the likelihood that it will be eroded.

How to prevent seed and soil erosion on slopes and hills?

1. Prepare and plant your slope or hill: Prepare your soil just as you would to plant grass seed in other parts of your lawn. Spread your seed according to the rate on the seed package. Then apply a starter fertilizer such as Pennington UltraGreen Starter Fertilizer 22-23-4.

Which is the best way to check soil erosion?

Summary Powered by GitBook Methods of Checking Soil Erosion Methods of Checking Soil Erosion Avoiding degradation of land Controlling of grazing activities by livestock Planting of trees to serve as wind breaks and shelter cover for soil. Growing of cover crops such as beans, cowpea, groundnut etc.

What happens if soil erosion is left unchecked?

Left unchecked, erosion can wash away soil on a slope, cause channels in the slope’s soil, pile up soil and rock at the base of a slope, block streams and creeks, or undermine the flat land above a slope.

Run-off from heavy spring or summer rainfall is not the only face of erosion — wind can just as easily blow soil particles down a slope.
