Abstract:
Soil is a complex material that is extremely variable in its physical and
chemical composition and is formed from exposed masses of partially
weathered rocks and mineral composing the earth’s crust. Soil formation is
strongly dependant on the environmental conditions of both the atmosphere
and the lithosphere. The soil body is a product of factors (Dokuchaev, 1883
and Jenny, 1941) like climate, time, organisms, topography and parent
materials. The interactions of these factors result in great variability in soils
(Buol et al., 1973). The upper soil horizon may contain valuable information
about the soils, such as soil degradation processes, salinity, organic matter,
crust formation, soil moisture, soil run-off and infiltration, which may be
mainly utilized for evaluating the soil fertility using the Remote Sensing
techniques.
Remote Sensing means acquiring information by using satellites and
spacecraft about a phenomenon object or surface at a remote vantage point
without making physical contact with the object or subject.
