Soil pH is a measure of the soil acidity or soil alkalinity. An acid solution has a pH value less than 7. While a basic solution always has a pH larger than 7.
Soil pH is an important consideration for farmers and gardeners for several reasons:
- Many plants and soil life forms have a preference for either alkaline or acidic conditions, affecting the choice of crop or plant that can be grown without intervention to adjust the pH.
- Diseases affecting plants also tend to thrive in soil with a particular pH range
- The pH can affect the availability of nutrients in the soil.
