Solution
- The presence of capillary water is essential.
- The rate of water absorption is maximum at soil temperatures between 20°C and 30°C.
- High concentrations of solutes in soil water reduce the rate of absorption of water.
- Poorly aerated soil shows poor absorption rates.
- Increased transpiration accelerates the rate of absorption of water in the irrigated soil.
