# Study the pH and water holding capacity of different soil samples.

AIM: To study the pH and water holding capacity of different soil samples.

REQUIREMENTS: Soil samples, measuring cylinders, funnel, filter papers and pH indicator.

PROCEDURE:

Take 2 funnels and line them with filter paper

Put these funnels in a measuring cylinder

Put the 2 soil samples in  separate funnels

The weight of soil sample should be same in both (25g)

Pour equal amount of water in both funnels (25 ml)

Let the water drip in the cylinder

Not the volume of water collected

OBSERVATIONS:

The volume of water collected in cylinder of sample A was more than sample B

Also, the pH of sample A was higher

Calculations:

Volume of water retained by soil = Vol. of H2O poured-Vol. of H2O collected in cylinder

Water holding capacity = (Vol of H2O retained/Vol of H2O required) x 100

CONCLUSION:

Soil sample A is roadside soil and sample B is garden soil as sample B has more water holding capacity.

PRECAUTIONS:

The water should be poured slowly

The measuring cylinders should be properly calibrated.

It is right but give me the details about how the garden soil can have more water holding capacity?

3. Noor says:

I needed this for my practical….. Great Thanks. For the help.
