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.[1]
Sometimes terms which refer to branches of soil science, such as pedology (formation, chemistry, morphology and classification of soil) and edaphology
(influence of soil on organisms, especially plants), are used as if
synonymous with soil science. The diversity of names associated with
this discipline is related to the various associations concerned.
Indeed, engineers, agronomists, chemists, geologists, physical geographers, ecologists, biologists, microbiologists, sylviculturists, sanitarians, archaeologists, and specialists in regional planning, all contribute to further knowledge of soils and the advancement of the soil sciences.
Soil scientists have raised concerns about how to preserve soil and
arable land in a world with a growing population, possible future water crisis, increasing per capita food consumption, and land degradation.[2]
