Water holding capacity of the soil depends upon

Options

A. chemical composition of soil
B. particle size of soil
C. aggregation of soil particles
D. all of these

Answer

D

Explanation

The quantity of water that soil can retain after flowing down of the gravitational water is called its field capacity or water holding capacity. It depends on chemical composition of the soil which means types of ions present and hence pH of the soil. Size of soil particles and their aggregation form pores in soil. Large pores take part in percolation of water in the soil but small pores hold water by capillarity.
