Fertility Testing: 1. First remove about 5 cm of topsoil, then mash the soil down to a depth of 13cm and clean any organic impurities that could affect test results in the soil, such as leaves, roots, etc. 2. Moisten the soil with water before testing. 3. Clean the probes with wipe or tissue. 4. Select the fertility testing mode. 5. Insert the electrode (above 60mm) into soil, wait for about 10s and read the value. 6. Record data. Remove the tester from the soil, clean and dry the probes.
PH Testing: 1. First remove about 5 cm of topsoil, then mash the soil down to a depth of 13cm and clean any organic impurities that could affect test results in the soil, such as leaves, roots, etc. 2. Moisten the soil with water before testing (better use rainwater or distilled water). 3. Select the PH testing mode. 4. Moisten 3 probes and clean the right probe with wipe or tissue. 5. Insert the whole electrode into soil, wait for about 1 minute and read the value. 6. Record data. Remove the tester from the soil, clean and dry the probes.
Note: 1. Avoid touching stones; do not insert with too much force; clean the electrode in time after using; never immerse into water for testing. 2. Do not insert into soil for long time to avoid damage. 3. Size and color may be slightly different due to manual measurement and different light conditions. Thanks for understanding.
