Trees hold the soil firmly. Crop rotation is effective at enhancing soil structure.
Erosion Control Measures Scienceaid
Reforestation This is the method of restoring or restocking existing woodlands and forests that have been depleted due to lumber harvesting deforestation or other natural causes.
. Five main techniques that can help in controlling soil erosion are as follows. Presence of vegetation on land prevents raindrops from falling directly on the soil thus erosion of soil in areas covered by vegetation is prevented. Due to so many different erosive agents soil erosion is.
A ripraps goal is to is to slow and divert the flowing water. Soil s tabilization dust control and erosion control. Stream Bank Control 8.
The forest canopy intercepts the erosive force of rain drops and the forest Utter protects the soil and helps in absorbing more rain water thus reducing the runoff. BSteps can be cut on the slopes making terracesTerrace cultivation restricts erosion. 1 in hilly areas-aPloughing along th econtour lines can slow down the flow of water down the slopesThis is called contour ploughing.
The construction of roads and buildings exposes the soil to erosion. Apart from this these trees will also add colour to the landscape and help to control the desert spread. 2 Contour Farming- Contour farming may be defined as ploughing seeding cultivating and.
Terrace farming is practiced with successful results in Japan South-East Asia and the USA. Here is a list of the most common erosion control methods. Wind can lift the valuable top soil from one area and deposits in another area.
Soil erosion can be controlled by adopting land management practices and also by changing the pattern of some human activities which accelerate soil erosion. Slope gradient slope length and shape of slope are the important variables of landform that affect erosion processes for all types of soil erosion eg splash sheet rill. A buffer strip is an area of land maintained in permanent vegetation that helps to control air soil and water quality along with other environmental problems dealing primarily with the land that is used in agriculture.
This is why it is important to study all the different types of soil erosion carefully so that we can work together to combat the adverse effects of our human activity. Methods of soil conservation. Organic matter in soil increased with crop rotation or by incorporating organic fertilizers.
Rain Drop or Splash Erosion The erosion due to the impact of falling raindrops on soil surface leading to the destruction of the crumb structure is known as the raindrop or splash erosion. Shelter Belts - Peasants plant trees in several rows to reduce wind erosion. Biological Method 1.
I Contour ploughing or ploughing along the contour lines of a highland can decelerate the flow of water down the slopes. One great and natural option to help to control erosion on slopes is by using plants. These methods or ways are Reforestation Growing Grass or Planting Vegetables Contour Plowing and Terracing Planting Trees around Farmlands Strip Cropping and Crop Rotation.
In areas where wind erosion is more rows of trees may be helpful to check the flow of winds. Terrace Farming - On hilly slopes terraces act as bunds and prevent the soil from being washed away by running water. I Contour Farming ii Strip Cropping iii Terracing iv Gully Reclamation v Shelter Belts.
Western and central Himalayas have well developed terrace farming. For effective control the width of the contour strip should vary inversely with the length of the slope. 1 Riprap- process uses rough loose stone on an embankment slope to prevent erosion.
Only using measuring ropes dibbers and a supply of seedlings or saplings. Organic matter binds to soil particles together which reduces Soil erosion. This article throws light upon the top nine biological methods for controlling soil erosion caused by water.
Soil binders have multiple purposes. Ii Terrace cultivation or cutting of steps around the slopes to provide land for agriculture also checks downhill flow of water and controls soil erosion eg as in Western and Central Himalayan region. The different types of flow and their velocities may be turbulent or laminar steady or unsteady uniform or non-uniform and influence the extent of erosion Landforms.
Som e soil binder products can combat all these issues at the same time. There are certain methods or ways in controlling soil erosion. Sand fences are employed to control erosion and to recruit new material in desert areas.
The leaf litter that protects the soil from erosion is also lost during logging. There are also several methods used. The biological methods are.
Mining activities also disturb the land and leave the soil more prone to erosion. They are called wind breaks. Soil blowing away can also be controlled if local shrubs and small trees planted in a systematic way.
Planting on a slope can be more difficult. Afforestation of economic plants should be done on contour benches to the specific needs of the area. Wind is a powerful agent of erosion in arid and semi-arid lands with little rainfall.
Fertilization and Maintenance of Soil Fertility 6. Wind can lift the valuable top soil from one area and deposits in another area. This is a very slow process and often remain unnoticed.
The canopy of the trees protects the soil from heavy rainfall. Deforestation unsustainable agricultural practices roads climate change and urban sprawl have led to a significant increase in soil erosion. The different soil erosion types are explained below.
Forests play an important role in controlling soil erosion. Silt Retention Dam 9. The roots of plants act as natural ways to hold in the round and soil and anchor the soil.
Turf grass Some have argued that turf grass might be the best defense against soil erosion. The process is fairly straightforward. The detachment and transportation of soil particles by flowing rainwater is called sheet or wash off erosion.
Strip cropping should be combined with crop rotation so that a strip planted to a soil depleting erosion-facilitating corn crop one year will be sown to a soil enriching and protecting strip of legumes the next. B Wind erosion.
