• Soil pH value is a very important factor for the quality of crops.
• Most of crops cannot survive in too acid or too alkaline soil.
• Get the right pH reading for your Crop is very important.
• Measuring soil pH and moisture, as far as possible to probe deeply into the earth and probe the upper portion for about 1 cm.
• On the table is 2.5-9 numerical, numerical 7 basic is neutral, the smaller the number shows that the greater the acidity, please adjust soil pH value according to plant varieties.
• Please pay attention that insert electrodes without touching the stone, not too hard, otherwise easy to damage the electrode, clean electrode after use.
