Metodología para medir pH en suelos
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.
