1.	Question : What are three fractions of water in the soil?
Answer» Solution :(a) Gravitational water. The fraction of water which reaches the water table by passing through spaces between soil particles from surface is called gravitational water. It is not available to plants because it lies beyong the REACH of ROOTS. (b) Capillary water. Water HELD in small pores against the force of gravity by capillary FORCES is called capillary water. It is readily available to plants for absorption by roots. (c) Hygroscipic water. The water which is absorbed on soil particles is called hygroscopic water . This film of water is held by strong attractive forces between soil particles and water molecules. This water is not available to plants.
