Soil erosion is also major ecological problem that doesn 't receive adequate media coverage like this is the case with climate change and air pollution. It is very difficult to find the adequate definition for soil erosion, mostly because soil erosion is studied by different scientific fields like geomorphology, ecology, agricultural engineering, hydrology, and each of these disciplines has different priorities when defining soil erosion.

to prevent soil erosion we can practice following:

afforestation

different cropping paterns like strip cropping, terrace cropping, contour ploughing etc.

Soil erosion is also major ecological problem that doesn 't receive adequate media coverage like this is the case with climate change and air pollution. It is very difficult to find the adequate definition for soil erosion, mostly because soil erosion is studied by different scientific fields like geomorphology, ecology, agricultural engineering, hydrology, and each of these disciplines has different priorities when defining soil erosion.

The simplest soil erosion definition would be "a form of soil degradation that affects natural environment and agriculture". The most common consequences of soil erosion are loss of soil structure, poor internal drainage, soil acidity problems, and huge loss of organic matter in the soil.

The thing you also need to know about the soil erosion is that this process is naturally occurring, and has been happening on our planet for more than 450 million years, ever since the time first plants on land formed the first soil structure.

So soil erosion is natural process. But if soil erosion is natural process why so many environmentalists refer to it as one of the biggest environmental problems? This is because soil erosion process has been increased dramatically by human land use such as industrial agriculture, deforestation, and urban sprawl. Nature ensures that erosion is kept at acceptable levels while industrial agriculture causes much higher rate of erosion that results in reduction of vegetation cover on the surface of the soil and does great damage to soil structure and plant roots.

To make things as simple as possible we could say that as long nature does the erosion work, erosion is in fact healthy for ecosystems and surrounding environment but as soon humans step in we are talking about excessive soil erosion that is very damaging to our environment.

Is there any solution that could stop excessive soil erosion, and reduce its negative environmental effects? Well, if we were to improve land use practices that would be of great help in limiting erosion, for instance by using practices such as terrace-building, conservation tillage practices, and tree planting.

I also need to mention that soil erosion is not the only form of soil degradation as there are also other forms of soil degradation such as salinisation, nutrient loss, and compaction. Soil erosion also need to be distinguished from weathering which is the process of chemical or physical breakdown of the minerals in the rocks, although the two processes may occur concurrently.

 thre r many measures to cntrl soil erosion ;-

  1. plant more and more trees , it will bind the soil together nd will prvnt its removal
  2. terrace farming should be done so that there should be something to check the high speed cmng water along with the soil
  3. cnstrctn of dams on hill slopes will help in the utilization of the water flowfor irrigational purposes
  4.  soil erosion can also be reduced by reducing pressure of grazing esp. on hill slopes  etc.....

Soil erosion can be a major problem for you if you have a garden, plant beds or a farm. Preventing soil erosion is a responsibility that we all have to take seriously. There are several things that you can do to prevent soil erosion and protect your plantings.

    • 1

      Prevent soil erosion by planting vegetation, trees, ground cover, shrubs and other plants. Roots from these plants will help hold soil in place on the ground. Soil will not blow away due to wind, or be washed away from rain as easily.

    • 2

      Create windbreaks, which are barrier rows planted along the windward exposure of a plot of land. Windbreaks made out of trees, such as evergreen trees or bushes help prevent erosion by preventing wind from blowing across your land.

    • 3

      Grow cover crops on farm land. When land is not being used during the off season, cover crops can help prevent soil erosion due to wind and rain. Legumes (beans) are often used as cover crops.

    • 4

      Apply mulch to retain moisture and also help prevent soil erosion. Topsoil is not as likely to be washed or blown away when it is covered by mulch. Mulch is often used in flower beds.

    • 5

      Construct surface runoff barriers, such as edging made of bricks or stones, can help prevent soil erosion by minimizing runoff. If runoff is minimized, soil is less likely to be carried away by groundwater runoff.

    • 6

      Use contour farming when farming on sloped areas. This conservation technique is to follow the actual topography of a slope when planting crops. Using the natural lay of the land in this way can also prevent soil erosion.

    • 7

      Try terrace farming and gardening to decrease groundwater runoff. Create nearly level layers of crops on a hillside.

 Soil erosion is being caused by deforestation.The main point to prevent soil erosion is 'stop cutting trees.

 we can stop soil erosion by:-

planting more & more trees = afforestation.

limited grazing of animals should be done.

tarace farming should be practiced.

strip croping should be done.

construction of dam should be done.

1)on hilly areas step farming is done 

2)by planting tree 's

3) by building embankment 's near water bodies
