Question: What Is Soil Degradation Process?

What are the steps to control soil degradation?

Here are a few to note:Wind breaks.

Artificial and natural windbreaks, such as shrubs, reduce the erosion effects of wind.

Terracing.

Terracing of slopes reduces the effects of water runoff and helps conserve rain water.Strip farming.

Crop rotation..

What is soil degradation Class 10?

Land degradation means decrese in the quality of the land .,,such that its nutrients and fertility is lost and is in incapable of growing crops ..the causes of Land degradation are .. 1) Soil pollution. 2) Soil Erosion. 3) Over grazing. 4) Extraction of minerals at a repeated stage..

What are the types of soil degradation?

Examples of soil degradationwater erosion (includes sheet, rill and gully erosion)wind erosion.salinity (includes dryland, irrigation and urban salinity)loss of organic matter.fertility decline.soil acidity or alkalinity.structure decline (includes soil compaction and surface sealing)mass movement.More items…•

What is the effect of soil degradation?

The effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species. And degraded lands are also often less able to hold onto water, which can worsen flooding.

What is desertification of soil?

Desertification is a very broad term, which has been defined in many different ways. One definition is “land degradation in arid, semi-arid and dry sub-humid areas resulting from various factors, including climatic variations and human activities”1.

What causes soil degradation?

Soil degradation causes include agricultural, industrial, and commercial pollution; loss of arable land due to urban expansion, overgrazing, and unsustainable agricultural practices; and long-term climatic changes. … The issues of soil health and impacts on human well-being are discussed in detail in Chapter 27.

Why is soil degradation bad?

Its impacts can be far-reaching, including loss of soil fertility, destruction of species habitat and biodiversity, soil erosion, and excessive nutrient runoff into lakes. Land degradation also has serious knock-on effects for humans, such as malnutrition, disease, forced migration, cultural damage, and even war.

What is an example of land degradation?

Land degradation here mainly refers to the loss of life-supporting land resource through soil erosion, desertification, salinization, acidification, etc. Deforestation accounts for the major land degradation problem as it results in severe soil erosion, flood, and loss of fertile soil.

What is physical soil degradation?

Physical deterioration of soil involves the destruction of soil structure, dispersion of soil particles, sealing of pores, compression and increasing density, consolidation, compaction and reduced root penetration, low infiltration, waterlogging and runoff, and accelerated erosion.

What are the 4 types of soil erosion?

Rainfall, and the surface runoff which may result from rainfall, produces four main types of soil erosion: splash erosion, sheet erosion, rill erosion, and gully erosion.

What are three types of soil degradation?

Soil degradation can be classified into four main types of degradation: water erosion, wind erosion, chemical deterioration and physical deterioration.
