Explain how soil pollution and soil erosion could be prevented.
Soil Pollution: The contamination of soil with waste materials like polythene bags and plastics, pesticides, fertilizers, acid rain and industrial chemical wastes etc. that reduces the productivity level is called Soil pollution.
Prevent by soil pollution: In case of organic farming instead of using chemical fertilizers, insecticides and herbicides, bacterial fertilizer nutrients; use compost, green manure, bacterial culture, organic manure, bio-pesticides, and bio-agents that leads to less soil pollutiion. This reduces the degradation of the soil.
By reducing the use of plastics, we can use jute and paper bags that is how we can reduce soil pollution.
Soil Erosion: The removal and trasportation of fertile top layer of soil from its original position by strong winds or fast running rainwater is called soil erosion.
Prevent by soil Erosion: Crop rotation -Rotating in high residue crops such as corn and small grain etc. that can reduce erosion as the layer of residue protects topsoil from being carried away by wind and water.
By preventing deforestation and avoiding overgrazing of animals.
Planting more and more trees (afforestation) will result in the reduction of soil erosion.
