Soil is formed from physical and chemical weathering of rocks -
processes described historically because they involve eons of
time-by glaciation and by wind and water transport of soil
materials, later deposited in deltas and loessial planes. Soil
undergoes further transformations over time and provides a habitat
for biological life and a base for the development of
civilizations. Soil is dynamic -always changing as a result of the
forces of nature and particularly by human influences. The soil has
been studied as long as history has been documented. Numerous
references to soil are found in historical writings such as
Aristotle (384-322 B. c. ), Theophrastus (372-286 B. c. ), Cato the
Elder (234-149 B. C. ) and Varro (116-27 B. c. ). Some of the
earliest historical references have to do with erosional forces of
wind and water. The study of soils today has taken on increased
importance because a rapidly expanding population is placing
demands on the soil never before experienced. This has led to an
increase in land degradation and desertification. Desertifica tion
is largely synonymous with land degradation but in an arid land
context. Deterioration of soil resources is largely human induced.
Poverty, ignorance, and greed are the indirect causes of
desertification. The direct cause is mismanage ment of the land by
practices such as overgrazing, tree removal, improper tillage,
poorly designed and managed water distribution systems, and
overexploitation."
