Water Absorption

Water status of a plant is determined by two major factors: i) water absorption and ii) water loss. We deal with water absorption in this section and water loss in the following section. Water absorption is regulated by soil factors, rate of transpiration and size and distribution of roots. The soil factors that regulate water absorption are:

1. Soil water content,
2. Difference in water potential between soil and root,
3. Concentration of soil solution,
4. Soil temperature and
5. Aeration of the soil.
