Importance of soil structure
It controls passage of water through the soil (soil drainage). Granular structure enables more rapid movement of water into the soil than platy.
It controls the passage of air through the soil ( aeration)
Controls soil temperature through its control on aeration.
Controls the water holding capacity of the soil.
Controls soil pH by controlling the passage of air and regulating the amount of carbon dioxide in the soil. High levels of carbon dioxide cause acidity.
It controls the workability of the soil i.e. single loose grained soils are easily worked on and less sticky.
It controls the ability of plant roots to penetrate into the soil.
It influences the occurrence of soil erosion.
It influences the availability of plant nutrients in the soil.
