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 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.
It really saved me !! I had my prac yesterday n didnt knew ne thng …. So thankyou soooo muchh
Thank you so much..it was helpful.
Thanks dude its a very help full for me an all
