13. What is Soil Science ?
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 soil.
These properties in
relation to the use and
management of soil.

14. Reason for studying soil:
• A prime reason for
studying soils is to obtain a
general concept as to what
they are and how they can
and should be used.
• Such a concept is essential
to understand how soil can
serve the engineer, the
farmer, and the home
owner.

15. Scope of Soil Science
Soil Geology:
The study of the
geological
materials from
which soil is
derived and its
process of
formation.

16. • Study of
chemical
component
of soil, their
interaction
with one
another.

17. Soil physics:
Study the effects of
physical laws on
the evolution of
chemical and
physical properties
of soil.

18. Soil Biology:
Study the effects of
plants, animals and
soil microorganisms
on the evolution of
soils.

19. Branches of soil science
Pedology.
Edaphology.

20.  It deals with soil formation, soil genesis, soil
classification and description of soil
properties.

21. Edaphology:
Study of soil in relation to growth, nutrition
and yield crops or plants.
