The pH meter was calibrated using pH 7 buffer solution.
Then the meter was adjusted with known pH of buffer solutions 4.0 and 9.2.
20 g of soil was weighed and transferred into 100 mL beaker.
40 mL distilled water was added and stirred well with a glass rod.
This was allowed to stand for half an hour with intermittent stirring.
To the soil water suspension in the beaker, the electrode was immersed and pH value was determined from the automatic display of the pH meter.
