Human activity is the main cause of soil degradation. Agriculture plays a large part in soil degradation, especially clearing, irrigation, the spreading of chemical fertilizers and pesticides, overgrazing and even the passage of heavy farming equipment. Tillage and the clearing and deforestation of large plots of land also lead to soil degradation. Improper drainage in agricultural fields also contributes to soil degradation.
there are many human activities which cause soil erosion here is one of them; deforestation: cutting down of trees on large scale cause the degradation of soil because when rain comes and there are trees trees do not allow soil to move from its place .
Soil erosion and depletion are the major threats to soil as a resource. Both human and natural factors can lead to degradation of soils . Factors which lead to soil degradation are deforestation, overgrazing, overuse of chemical fertilisers or pesticides, rain wash, landslides and floods.
Over-cultivation is the biggest cause of soil erosion in the Philippines. A secondary cause is the amount of rainfall the country receives.
Land degradation is the land that is being degraded in some form that is negative. Soil erosion is when rock and soil is removed from one location of land to another.

The principal cause of soil degradation along the Murray River is improper land use. Certain agricultural practices cause erosion, whilst over-iriigating causes increased salinity.

Heavy rains are responsible for most soil degradation in the prairies of the United states. There are not enough plants to keep the soil in place.

Soil degradation is when soil deteriorates because of human activity and loses its quality and productivity. It happens when soil loses its nutrients, or its organic matter. It also happens when the soil structure breaks down, or if the soil becomes toxic from pollution. The primary cause of soil degradation is erosion, but compaction, salinization, and depletion by nutrient demanding crops may also cause degradation. Soil degradation is which the movement of soil particles from one place to another by wind or water, is considered to be a major environmental problem. Erosion has been going on through most of earth's history and has produced river valleys and shaped hills and mountains. Such erosion is generally slow, but the action of man has caused a rapid increase in the rate at which soil is eroded (ie. a rate faster than natural weathering of bedrock can produce new soil). This has resulted in a loss of productive soil from crop and grazing land, as well as layers of infertile soils being deposited on formerly fertile crop lands; the formation of gullies; siltation of lakes and streams; and land slips. Man has the capacity for major destruction of our landscape and soil resources. Hopefully he also has the ability to prevent and overcome these problems.
