Question

Describe an experiment to show the water-holding capacity of different types of soil.

Answer 1

Take a funnel, filter paper, measuring flask (according to the number of soil types we compare) and kitchen weighing scale.
Place the filter paper in the funnel and place the funnel on the measuring flask. Weigh about 25 g of each sample of soil and place it in each measuring flask. Pour 50 ml of water in each funnel. Record the speed at which the water drains out through each funnel into the measuring flask.
To determine the water-holding capacity of different soil, subtract the amount of water in the measuring flask from the amount of the water taken, i.e., 50 ml. Higher the resultant value of volume of water in the funnel, larger is the water-holding capacity of soil.
