Soil npk tester description
Soil N-P-K Meter Testing
Test 1: Quick test method: Take an appropriate amount of distilled water to irrigate the soil to be measured. Make sure that the water can penetrate to a depth of at least 10 cm. The best humidity is 60%~80%RH. Insert the metal probe slowly and vertically into the soil to a depth of about 6-8 cm. Ensure that the soil is in full contact with the metal probe. After pressing the power button, the tester will display the measured value after about 2 seconds. The compactness of the soil will affect the measurement results. You should perform multiple tests at the same and different points, and use the average value as the final result.
Test 2: Accurate measurement method: Use a container to mix dry water in a ratio of 3:1. Stir it into a puree. Put the metal probe into the mud about 6-8 cm deep. In about 2 seconds, the tester will display the measured value. Take the average of multiple measurements.
After each test, wipe the metal probe with a towel or tissue paper. Make it clean and dry. Until the display shows “0”.
