Write about the conservation of soil causes and effects

The direct damages from bank erosion include loss of productive farmland, undermining of structures such as bridges, increased need to clean out and maintain drainage channels and washing out of lanes, roads and fence rows. Regions of Low and Uncertain Rainfall: Precipitation is the most forceful factor causing erosion.

Doing nothing will only allow the pollution to progress to a point where our soil becomes the cause of major health epidemics. This form of erosion is a major delivery mechanism for water erosion. Movement of soil by splash erosion is the primary cause of sheet erosion.

Seeds and plants can be disturbed or completely removed by the erosion.

What is Soil Conservation?

This Factsheet looks at the causes and effects of water, wind and tillage erosion on agricultural land. This technique increases the amount of water that penetrates the soil and can increase organic matter of the soil which leads to larger yields. Korean Natural Farming — This method takes advantage of natural and indigenous microorganisms to produce fertile soils that yield high output and gets rid of the need to use herbicides or pesticides.

Eliminating the use of nitrogen fertilizer and fungicides can increase yields and protect crops from drought and flooding. It is practiced in western and central Himalayas Keyline design[ edit ] Keyline design is an enhancement of contour farming, where the total watershed properties are taken into account in forming the contour lines.

As an example, compacted subsurface soil layers can decrease infiltration and increase runoff. Unless pollution levels are brought down, nothing in this world is immune, no life is safe, and the future of this world is bleak.

In addition, blowing dust can affect human health and create public safety hazards. During flash floods, the damage is much accelerated. In the midst of the conversations on pollution, one of the more commonly overlooked side effects of our daily activities is soil pollution.

Dry Farming — In areas with a very low amount of rainfall, crops which require very little water should be grown, this will lead to the preservation of the natural levels of moisture and nutrients in the soil.

What are the Main Causes of Soil Degradation?

This, in turn, impacts future crop production. Most of the Indian soils are deficient in nutrients and organic matter. According to National Commission on Agricultureabout 6 million ha area is under water-logged condition. Sediment that reaches streams or watercourses can accelerate bank erosion, obstruct stream and drainage channels, fill in reservoirs, damage fish habitat and degrade downstream water quality.

The factors which affect soil micro flora and fauna also reduce the biological or microbial activity of soil adversely. These factors reduce the yield. Tillage and cropping practices that reduce soil organic matter levels, cause poor soil structure, or result in soil compaction, contribute to increases in soil erodibility.

Essay on Soil Erosion: Factors, Types, Causes and Effects

Crop management systems that favour contour farming and strip-cropping techniques can further reduce the amount of erosion. Cover crops also help suppress weeds. Soil conservation is one such step that protects the soil from being washed away.

The soil profile is changed; the top soil is turned deep inside the dumps.Causes and Effects of Soil Pollution: The main reason why the soil becomes contaminated is due to the presence of man made waste.

The pollution of soil is a common thing these days, and it happens due to the presence of man made elements. Deforestation causes fast degradation when the soil is steep sloppy or easily erodible.

Soil Pollution – Causes, Effects and What To Do About It?

Destruction of natural vegetation cover is a major factor responsible for erosion of soils by water and wind. According to Global Assessment of Soil Degradation (GLASOD), deforestation is the main cause of soil erosion by wind in about 98% of the area. Environmental Pollution refers to the introduction of harmful pollutants into the environment.

The major types of environmental pollution are air pollution, water pollution, noise pollution, soil pollution, thermal pollution, and light pollution. Deforestation and hazardous gaseous emissions also leads to.

What is Soil Conservation? Soil Conservation is the name given to a handful of techniques aimed at preserving the soil. Soil loss and loss of soil fertility can be traced back to a number of causes including over-use, erosion, salinization and chemical contamination.

Soil conservation is the preventing 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.

Causes of Soil Erosion: Soil erosion is also referred to as the creeping death. The causes of soil erosion are directly related to improper landuse, and are, therefore, entirely man-made.

Essay on Environmental Pollution: Causes, Effects and Solution

These include the following: 1. Deforestation: Removal of vegetation cover has caused widespread erosion in Western Ghats, Uttar Pradesh and in Himachal Pradesh. 2.
