Question

short note on soil conservation

Answer 1

Soil conservation is the prevention 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. A sequel to the deforestation is typically large scale erosion, loss of soil nutrients and sometimes total desertification.

short note on soil conservation:

• Soil conservation is necessary because it can hamper the survival of plants and animals, as well as the shortage of food and drought, which can occur if they are not preserved.

• Soil is one of the most important natural resources that help to drive the life of every species on our planet.

• We humans use it for agriculture and farming whereas animals use soil to dig holes as a place for them to stay and hide from other predators.

• Erosion could occur which would take away huge chunks of farming lands.

• Deforestation should be controlled in order to conserve fertile soil.

• Dumping waste and chemical components in the environment can also degrade soil quality.
