Why Test Soil pH, Moisture and Fertility?
1. Soil fertility determines the lack of or excessive nutrient fertility absorbed by plants during growth. Plants are prone to lodging, disease and insect damage, growth inhibition, and dwarf plants.
2. Plant growth depends on soil moisture and nutrients. When there is too little or too much water, it will affect the growth of plants and even cause plants to die.
3. The pH can directly reflect whether the soil is suitable for plant growth.

Notice:
The test fertilizer intensity is determined by the soil moisture and ph value. Proper watering and fertilization will make the plants grow better.
This instrument cannot test the nutrient soil of sand and gravel soil. Clean the probe after use and dry it.
