How to analyze soil fertility

1. Remove approximately 5 centimeters of topsoil first； Then crush the soil downwards to a depth of 13 centimeters. And clean up all organic impurities in the soil that may affect the test results, such as leaves, roots, etc.

2. Soak the soil with water to form a muddy state. (It is best to use rainwater or distilled water).

3. Use a cleaning cotton or tissue to wipe the probe clean.

4. Move the function key to the first gear from the left and up.

5. Insert the probe into the tested soil until the distance between the soil and the machine body does not exceed 2.5 centimeters. Wait up to 10 seconds until the pointer stabilizes before reading the data.

6. Record data. Remove the probe from the soil and thoroughly clean it. The judgment criteria for the analysis results are as follows

TOO LITTLE

Nitrogen less than 50 ppm

Phosphorus less than 4 ppm

Potassium less than 50 ppm

IDEAL

50-200 ppm

4-14 ppm

50-200 ppm

Too Much

Greater than 200ppm

Greater than 14 ppm

Greater than 200ppm

Unit ppm: parts per million

If the analysis results show “TOO LITTLE“, which means: lack of

Please use liquid fertilizer to supplement nutrients for the different plants you plant. (Please refer to the instructions on the fertilizer packaging bag for details)

If the analysis results show “IDEAL“, it means: ideal. According to the different plants you plant, use fertilizer and apply it once a month in combination with irrigation.

If the analysis results show “TOO MUCH“, it means: excessive

1. Watering extensively to dilute and wash excess nutrients；

2. For potted plants, they should be transplanted back into new soil；

3. Do not apply any more fertilizers, but you can add feces, compost, plant residues, leaves, and other organic substances to the soil. How to analyze the pH value of the soil

1. Firstly, remove about 5 centimeters of the surface soil of the tested soil； Then crush the soil downwards to a depth of 13 centimeters. And clean up any organic impurities in the soil that may affect the test results, such as leaves, roots, etc.

2. Soak the soil with water to form a muddy state. (It is best to use rainwater or distilled water)

3. Move the function key to the rightmost gear and move it up.

4. Wet probe. Use a cleaning cotton pad to wipe the rightmost root of the three probes clean.

5. Fully insert the probe into the tested soil.

6. Wait for 1 minute to read the data.

After the test is completed, wipe the probe clean and let it dry.

hot tip

Please do not insert the probe into the soil for a long time, and do not use this device to test the liquid to avoid damage.
