What
is Soil?
Soil is the voluminous upper part
of the earth crust that supports land plants by holding them and by
providing them with nutrients, water and air.
Soil consists of unconsolidated
inorganic particles, partially decomposed organic fragments, and pore
spaces between and within.
Soil Pore spaces contain soil
air, and soil solution.
Therefore, a soil volume consists
of solid, liquid and gaseous phases
It is inside the pores that soil particles,
soil water and living
plant roots interact and create
the Soil - Water
- Plant
relationship that is the key to safe growth and successful
production of land plants
Quantity of pores, shape of pores and the magnitude of pores depend
on the geometrical and mineralogical properties of the surrounding
inorganic soil separates, their extent and their
physical arrangements, or simply their Textural
Classification
and Structure
Adequate knowledge of Soil Textural Classification and Soil Structure
can contribute greatly to the advancement of the
proper management of Soil - Plant
- Water relationship
It is inside the pores that soil particles react with soil
water chemically, dissociate,
and release chemical molecules that determine the chemical constituents
of the soil solution
