The document describes a procedure for determining the pH of soil using a pH meter. It involves making a 1:2 soil-water suspension by adding distilled water to soil in a beaker, stirring, and allowing it to settle. The pH meter glass electrode is placed in the suspension and three readings are taken and averaged to obtain the final pH value.

1. • pH was determined as per the method given by (Jackson, 1967).
• Reagents
• 1. Distilled water
• Glasswares
1. 100 ml beakers.
2. Stirring Rod
• Equipment
• 1. pH meter.
• Procedure

2. • Procedure
1.The calculation of pH was done in a soil-water suspension of 1:2
ratio.
2.Ten gram of soil was placed in a 100 ml beaker and 20 ml of
distilled water was added.
3. The soil was stirred well for five minutes and kept undisturbed for
some time followed by stirring again.
4. The glass electrode of the ph meter was then placed in the
suspension and the
• readings were noted in triplets.
5.The average value of the three readings was taken as the final ph of
soil suspension.
