SOIL EROSION

  • Naturally occurring process that affects all landforms.

  • It is the washing or blowing away (by water or wind) of the top layer of soil.

Rain and Cloud for Soil Erosion

  • Impact of raindrops on the soil surface can break down soil aggregates and disperse the aggregate material.

Wind for Soil Erosion

  • It is a serious environmental problem.

  • Attracting the attention of many across the globe.

  • Occurring mostly in:

    • Flat, bare areas

    • Dry, sandy soils

    • or anywhere the soil is loose, dry, and finely granulated

Effects of Soil Erosion

  • Effects of soil erosion can be felt on-site, meaning at the site of soil disruption. So, soil quality is reduced.

  • Crops are damaged due to sand storms.

SOIL CONSERVATION

  • It is the prevention of soil loss from erosion or reduced fertility caused by over usage, acidification, salinization or other chemical soil contamination.

AFFORESTATION

  • It is the establishment of forest or stand of trees in an area where there was no previous tree cover.

  • It is the process of planting large numbers of trees on land.

  • It is necessary to combat the issues of:

    • Global warming

    • Soil erosion

    • Pollution

  • Maintenance of biodiversity and ecological balances.

Mulching

  • It enriches and protects soil.

  • Helping provide a better growing environment.

  • One of the simplest and most beneficial practices
