Soil Sample Collection and pH Measurement Process

Introduction to Soil Sampling

  • Renato introduces himself as a student from Agoma, outlining the fundamental steps for soil sampling.
  • The first step involves selecting a location and clearing the surface of the ground to collect soil samples.

Soil Sample Preparation

  • Approximately 500 grams of soil is collected and stored for laboratory analysis.
  • In the lab, the sample is spread evenly on newspaper to dry for about 48 hours at room temperature.

Sieving Process

  • After drying, the sample undergoes sieving using a 2 mm mesh sieve to remove larger particles that could skew results.
  • A precise measurement of 10 grams of sieved soil is taken for further testing.

Preparing Soil-Water Solution

  • Water is added in a ratio of 1 part soil to 2.5 parts water; this mixture is agitated for approximately two hours.
  • The solution is allowed to rest undisturbed for 20 minutes before proceeding with pH measurement.

pH Measurement Procedure

  • Instruments are prepared for measuring pH; after resting, the pH meter is inserted into the solution ensuring complete immersion.
