Paragraph on soil erosion
Soil erosion is the process by which soil is removed from one location and transported to another. This can occur through natural processes, such as wind and water erosion, or it can be caused by human activities, such as farming and construction.
Soil erosion has significant impacts on the environment and human society. It can lead to the loss of fertile soil, which can have negative consequences for agriculture and food production. It can also contribute to the degradation of natural habitats, leading to the loss of biodiversity. In addition, soil erosion can cause water pollution and increase the risk of natural disasters, such as landslides and floods.
There are several ways in which soil erosion can be prevented or reduced. One way is through the use of conservation tillage practices, which involve leaving crop residues on the field after harvest rather than tilling the soil. This helps to protect the soil from erosion by wind and water. Other methods include the use of cover crops, which help to hold the soil in place and prevent erosion, and the use of terracing, which involves creating stepped slopes in fields to reduce the impact of water erosion.
In addition, it is important for individuals and communities to be aware of the impact their actions can have on soil erosion. This includes considering the environmental impacts of farming practices, construction projects, and other activities that may contribute to soil erosion. By taking steps to reduce soil erosion, we can help to protect the environment and ensure that we have the resources we need to sustain life on Earth.
Paragraphs on Soil Erosion
This degrades the soil and results in desertification. Wind erosion is a serious problem in arid and semi-arid parts of North West India. Soil erosion is topsoil, which is organic soil made up with rich nutrients. The loss of soil due to shifting agriculture is no less pronounced. Only high salt tolerant crops such as cotton, rape, barley etc.
Short Essay on the Soil Erosion & Its Conservation
Some portion of this land is permanently lost to agriculture. In conclusion, soil erosion can be prevented by ensuring we plant a lot of trees and the land are not bare. It is therefore essential that the soils should not be allowed to wash or blow-away more rapidly than they can be regenerated, their fertility should not be exhausted and their physical structure should remain suited to continued production of desired plant materials. Soil erosion can be divided into two very general categories:Geological erosion: Geological erosion occurs where soil is in its natural environment surrounded by its natural vegetation. Desertifications have several ecological implications.
The removal can be a slow and gradual process when soil is gradually blown away by the wind, or can be done in an instant when it is washed away by water. HUMAN OR NATURAL CAUSE: Eolian erosion is a natural phenomenon, but the surfaces it acts upon may be made susceptible to active wind shaping and transport by human actions, especially those, such as cultivation and over-grazing, that result in the reduction of cover vegetation. Weather systems in the mid-latitudes, such as "extratropical cyclones", are caused by instabilities of the jet stream flow. Also the farmers should be taught of controlling the quantity of creatures on their property so overgrazing did not happen. Retrieved 17 May 2012 from. There are severals steps known as andenes which are built into the side of a hill.
Soil Erosion: Paragraphs on Soil Erosion in India
But they never do that is why our main problem is soil erosion. Or if like many others, have you driven rapidly through the puddles to make the biggest wave possible? The sediments accumulate in the water and raise the water levels resulting in flooding. In India, wind erosion is most prominent in Rajasthan, Western Punjab and coastal tracts. There are too many variables to be taken into account and it stands out more clearly because of the variability of the weather, of crop diseases and pests. I guarantee on a rainy day in the big city …show more content… There have been many soil conservation measures that have been either recommended by agricultural agencies or demonstrated by top-down government. Ans: In hilly areas, terrace farming.
Paragraphs on Soil Erosion: Meaning, Causes and Forms
Eolian action also forms and shapes sand dunes, yardangs streamlined bedrock hills and other landforms. The rivulets in turn join together to form larger channels until gullies are formed gradually deep gullies cut into the soil and then spread and grow until all the soil is removal from the sloping ground. The flowing water during floods also erodes a lot of soil by creating potholes, rock-cut basins, etc. ADVERTISEMENTS: For example, the Nagas of Nagaland and the Juangs of Orissa are bound to migrate from one agricultural land to another as the fertility status of the soil declines due to primitive methods of tillage system following an annual burning of vegetal coverage. Causes of Soil Erosion 3. Within this paragraph, the major techniques that are being used to reverse the current trend of soil degradation will be explained.

The glacier went as far north as the Hudson Bay and as far south as the Ohio Valley. Soil erosion is caused by running water on sloping lands, by winds over the drier areas and in sandy soils of humid regions, and by waves on lake and ocean shore lines. Differential erosion by wind in the past may be detected through study of buried soil horizons developed on ancient erosional surfaces, which formed during dry wind erosion to wet soil formation climatic cycles. There would be no grass, no crops, no trees, and no sustenance for humans and other animals without dirt. Therefore plants help slow down a soil erosion. This has led to intense erosion of soil and the yields of potatoes have gone down by about 50 per cent in spite of heavy application of fertilisers.
What Is Soil Erosion?
Attrition is when the waves cause rocks and pebbles to smash into each other and eventually break into pieces. Also organic residues such as rice husks and rice straw can be added to promote formation of mild acid as a result of their decomposition. Steep slope, swift flow of rivers and scarce vegetation cover lead to water erosion. Gully erosion is more common in areas where the river system has cut down into elevated plateaus so that feeders and branches carve out an intricate pattern of gullies. Erosion can be caused by careless farming techniques that lead to water erosion.
Essay On Soil Erosion
Soil is important because it is the fuel to the plants that we need in order to survive and for all species to survive. So all the yield maps or other data provided is useless if the person on the receiving end does not know how to interpret it. Soil contains nutrients that are taken from decomposed animals and plants which turn to detritus. Running water, wind, waves of the sea and moving ice or glacier cause natural soil erosion. Due to its importance as a factor of degradation, and the limited scope of this paper, erosion will be the focus of this inquiry. They must be instructed to return wheat stubble and straw in the wake of reaping for organic material and anticipation against erosion. Tree planting should be done widely.
What is Soil Erosion? Causes, Effects of Soil Erosion, Soil Conservation
Richard T Wright, 2011 There are major practices that are the main Erosion In The Colorado River Everything on Earth cannot stay the same, except for the amount of mass on the planet. ADVERTISEMENTS: The flood plains of the Ganga and its tributaries in Uttar Pradesh and Bihar also suffer from the problem of soil erosion caused by water. There go all kinds of danger down the creek bed. Overgrazing and de-vegetation also increase soil erosion. Surface cover and runoff are great ways to manage soil erosion.
How To Prevent Soil Erosion
The total area affected by shifting cultivation is estimated to be 45 lakh hectares. Paragraph Causes of Soil Erosion : The main causes of soil erosion and depletion of soil or land resources can be enumerated as follows: a Heavy destruction of natural protective cover, like trees and grasses, by indiscriminate cutting down of trees, forest fires and overgrazing and burning of grassland. Punjab and Haryana have about one-fourth of the total land characterised by arid conditions. In addition to the direct loss of crop producing capacity, soil erosion increases the destructiveness of floods and decreases the storage capacity of water in reservoirs. Apart from this, it also takes place in relatively level country whenever large blocks of cultivation give rise to concentration of field run-off. Soil Salinity and Soil Alkalinity: Soil salinity and soil alkalinity are the results of over irrigation in canal irrigated areas.
