Choose a specific area of soil you want to test. Ensure it represents the general conditions of the field or site.
Make the points in an 'X' or 'Y' pattern
• One center point
• Four outer points (equal distance from the center, like 1-2 meters)
• Clear away grass, mulch, or loose debris at each sampling point.
• Ensure the soil surface is flat and undisturbed.
• Hold the penetrometer vertically above the point.
• Press it into the soil slowly and steadily.
• Check the pressure reading on the penetrometer (usually in pal or kg/cm²).
• Record the value for each point.
