What are the Main Causes of Soil Degradation?

Soil degradation has been defined as a process that leads to decline in the fertility or future productive capacity of soil as a result of human activity (United Nations Environment Programme, 1993). It occurs whenever the natural balances in the landscape are changed by human activity through misuse or overuse of soil.

The Effects of Soil Erosion Sciencing

Mar 13, 2018· The degradation of nutrients in soil is often a result of poorly conducted farming and agricultural practices that lead to soil erosion. Excessive irrigation and outdated tilling practices reduce the amount of nutrients in the soil and make it less fertile for natural vegetation and agricultural purposes. According to the Environmental Protection Agency, agricultural methods, such as purposely

Does soil compaction increase floods? A review ScienceDirect

Land degradation due to soil compaction from crop farming or grazing intensification is one of the potential drivers of this increase. A literature review suggests that most of the experimental evidence was generated at plot and hillslope scales. At larger scales, most studies are based on models. There are three ways in which soil compaction
