Soil water

Soil water is the major component of the soil in relation to the plant growth. The water is held within the soil pores. If the moisture content of a soil is optimum for plant growth, plants can readily absorb the soil water. Not all the water, soils can hold is available to plants. Much of water remains in the soil as thin film. Soil water dissolves salts and makes up the soil solution, which is important as a medium for supplying nutrients to growing plants. There is an exchange of nutrients between the soil solids and the soil solution and then between the soil solution and plants.
