Size: Approx. 26x6x3.4cm / 10.2x2.4x1.3in
Probe Length: Approx. 17.7cm / 7.0in
Package List:
1 x Soil Tester
Instructions:
- When measuring the pH and humidity of the soil, first insert the probe into the soil as deep as possible. (Above 10cm)
- Move the button to MOIST, MOIST is the moisture button. The corresponding table is MOIST, DRY is dry, WET is wet. The value 1-3 (red part) indicates the need for watering, 4-7 (green part) is appropriate, 8-10 (blue part) is too wet. Please adjust the watering time according to the variety of plants.
- Push the button to PH, PH is the pH button. The corresponding table is 8-3.5 value, ALKALINE is alkali, ACDIC is acid. The value 7 is basically neutral, the smaller the number, the higher the acidity. Please adjust the soil acidity and alkalinity according to plant species.
- The LIGHT button is the illuminance. The measurement range is 0-2000 lumens. The larger the value, the stronger the illumination is. Please decide whether shading is necessary according to the variety of plants.
- When using it, be careful not to touch the stone when inserting the electrode. Do not use too much force, otherwise it will easily damage the electrode. Wash the electrode after use.
Soil acidity and alkalinity
Soil acidity and alkalinity is also called "soil response". It is an acid-base reaction of soil solution. It mainly depends on the concentration of hydrogen ion in soil solution, expressed as pH value. The solution with pH equal to 7 is neutral solution; the solution with pH less than 7 is acidic reaction; the solution with pH greater than 7 is alkaline reaction.
Soil acidity and alkalinity can generally be divided into the following grades:
< 4.5 extremely strong acid
4. 5-5.5 strong acid
5. 5-6.5 acid
6. 5-7.5 neutral
7. 5-8.5 alkalinity
8. 5-9.5 strong alkaline
9. 5 extremely strong alkaline
Regulation of soil acidity and alkalinity:
- the improvement of acid soil often uses lime to neutralize active acid, latent acid, and improve soil structure. Purple shale powder, fly ash and grass ash can also be used.
- Artificial acidification of neutral and calcareous soils. Flowers in open fields can use sulfur powder (50g/m2) or ferrous sulfate (150g/m2), which can reduce 0.5-1 pH unit. It can also be watered with alum fertilizer and water.
- The application of gypsum in alkaline soil can also be phosphogypsum, ferrous sulfate, sulfur powder and acid weathered coal.
Note:
- When using, be careful not to touch the stone when inserting the electrode. Do not use too hard, or it will easily hurt the electrode.
- Please allow 0-1 inch error due to manual measurement. Thanks for your understanding.
- Monitors are not calibrated same, item color displayed in photos may be showing slightly different from the real object. Please take the real one as standard.
