Soil Components

Soil Components:  Soils consist of four major components: 
(1) mineral (or inorganic), (2) organic, (3) water, and (4) air. The
relative proportions of these four soil components vary with soil type and climatic conditions. Review the approximate proportions (by volume) of the four soil components in a mineral soil under optimum conditions for plant growth.
