**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 H_{2}O poured-Vol. of H_{2}O collected in cylinder

Water holding capacity = (Vol of H_{2}O retained/Vol of H_{2}O 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 was realy nice and effective

Thanks for giving data

oops!!! i got the correct answer..many many thanks to giving the xperiment data

…

Exactly. It is helpful.

Congratulations to you .

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

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