Soil Ecology, Soil Contamination and Soil Sciences

Soil ecology is the study of how soil organisms interact with other organisms and their environment – their influence on and response to numerous soil processes and properties form the basis for delivering essential ecosystem services. Soil contamination or soil pollution as part of land degradation is caused by the presence of xenobiotic chemicals or other alteration in the natural soil environment. It is typically caused by industrial activity, agricultural chemicals or improper disposal of waste. Soil science is the study of soil as a natural resource on the surface of the Earth including soil formation, classification and mapping; physical, chemical, biological, and fertility properties of soils; and these properties in relation to the use and management of soils.
