Question

What do you mean by soil erosion & how it can be conserve?

Answer 1

Soil conservation is the preventing of soil loss from erosion or reduced fertility caused by over usage, acidification, salinization or other chemical soil contamination. Slash-and-burn and other unsustainable methods of subsistence farming are practiced in some lesser developed areas.

Answer 2

Heya!

Here's your answer! ^^

Soil erosion is the washing away of the land surface or the top soil by the flowing water or wind is called soil erosion.

The methods of preventing soil erosion are -

=> Afforestation : Forests reduce erosion as the roots of trees hold the soil in place.

=> Shelter belts : Trees planted in lines or hedges around farmland reduce erosion by reducing the speed of the wind.

=> Terrace farming : It gives the water sufficient time to percolate into the soil and nourish the crop.

=> Soil cover : Soil left bare after harvesting a crop is covered with dried vegetation to prevent erosion.

=> Preventing overgrazing : the grass has a tendency to bind soil molecules, so even a very little grass on a field prevents erosion of soil. But if the grass is overgrazed, it leads the soil to erode.

Hope it helps! :)
