Question

The percentage of water left in the soil after the plant has undergone permanent wilting is called

• A. Field capacity
• B. Water holding capacity
• C. Wilting coefficient
• D. DPD

Answer 1

The correct option is C Wilting coefficient

In soil ecology, there are a number of factors determining soil health and quality. Water plays an important role in various aspects related to soil. Field capacity is the amount of water, in liquid or moisture form, retained in the soil after excess water has drained away and further percolation has ceased or reduced.

Water holding capacity is the amount of water that particular soil type can hold. It largely depends upon the composition of the soil.

The percentage of water left in the soil after the plant has undergone permanent wilting is called permanent wilting point and is represented by the wilting coefficient.

DPD is the diffusion pressure deficit is the difference between the diffusion pressure of pure water and solution.

So, the correct answer is 'Wilting Coefficient'.
