Osmotic potential vs osmotic pressure of saline soil
0 min read
- The osmotic potential of saline soils (having higher salt content) is lower than the normal soil.
- However, the osmotic pressure of saline soil is higher than the normal soil.
- Water always moves from high osmotic potential to low osmotic potential or low osmotic pressure to high osmotic pressure.
Note: The answer of the question number 48 on page no. 227 of An Insight into Agronomy book has mistakenly written as b. The correct answer is a i.e. osmotic potential of saline soil is low.
For better understanding, watch this lecture on water potential:
