How to analyze soil fertility
1. First remove the topsoil about 5 cm;Then mash the soil down to a depth of 13 cm.And clean the soil of any organic impurities that may affect the test results, such as leaves, roots, etc.
2. Soak the soil with water until it looks like mud.Use rain water or distilled water.
3. Wipe the probe with a clean cotton or paper towel.
4. Set the function key to the first gear position from the left.
5. Insert the probe into the soil under test until the soil is no more than 2.5 cm away from the airframe.Wait up to 10 seconds until the pointer is stable to read the data.
6. Record data.Remove the probe from the soil and thoroughly clean the probe.
The criteria for the analysis results are as follows
TOO LITTLE
Nitrogen less than 50 PPM
Phosphorus is less than 4 PPM
Potassium less than 50 PPM
IDEAL range
50-200 PPM
4-14 PPM
50-200 PPM
TOO MUCH
More than 200 PPM
More than 14 PPM
More than 200 PPM
· unit PPM: parts per million
If the analysis shows that "TOO LITTLE" means: lack
Please use liquid fertilizer to supplement your plants.(refer to the instructions on the fertilizer package for details)
The IDEAL, as it were, is IDEAL
Depending on the plants you grow, use fertilizer and combine it with irrigation once a month.
If the analysis shows that "TOO MUCH" means: TOO MUCH
1. Water in large quantities to dilute excessive nutrients;
2. For potted plants, replant them into new soil;
3. Do not apply any more fertilizer, but add manure, compost, plant residues, leaves, and other organic materials to the soil.
How do you analyze soil pH
1. Remove the measured topsoil about 5 cm first;Then mash the soil down to a depth of 13 cm.And clean the soil of any organic impurities that may affect the test results, such as leaves, roots, etc.
2. Soak the soil with water until it looks like mud.(preferably rainwater or distilled water)
3. Dial the function key to the right-most gear position.
4. Wet probe.Clean the rightmost of the three probe rods with a clean cotton sheet.
5. Insert the probe completely into the soil under test.
6. Wait 1 minute to read the data.
7. After the test, wipe the probe rod and dry it.
Special note
Do not place the probe in the soil for a long time and do not test the liquid with this device to avoid damage to it.
