What is soil deterioration, you ask?

Soil degradion refers to the loss of fertile land, making it difficult for plants to grow in that area. It is caused by depleted resources such as organic matter, fertility and nutrients.

What are the causes of soil degradation?

Examples for soil degradation

  • water eroding (includes sheet and rill erosion )
  • wind erosion.
  • salinity (includes dryland, irrigation and urban salinity)
  • loss or organic matter.
  • fertility decline.
  • soil acidity and alkalinity.
  • structure fall (includes soil compaction and surface sealing )
  • mass movement.

Why does poor soil quality pose a problem?

Soil erosion has far-reaching consequences beyond the loss fertile land. This has caused increased pollution and sedimentation of streams and rivers, which can clog these waterways and cause declines in fish stocks and other species. Degraded lands can also be less resilient to water, which can lead to flooding.

What is the best way to prevent soil degrading?

Both artificial and natural windbreaks (such as shrubs) reduce wind erosion. The added benefit of plants is that they “anchor” the soil and reduce erosion. Terracing slopes helps reduce water runoff and conserves rain water.

What are the five factors that influence soil formation?

The five factors are: 1) parent matter, 2) relief or topography and 3) organisms (including human), 4) climate and 5) time. A different soil type will result if a single parent material is exposed in different climates.

What are the destructive activities of soil?

Silt erosion is caused by wind and harsh climatic conditions, but humans can also cause it. Human activities include overgrazing or overcropping, deforestation, and overcropping. Farmers who have too many animals, such as sheep, cattle, or goats, on their land are called overgrazing.
