A soil pH of more than 7 is categorized as what?

A soil pH of more than 7 is categorized as alkaline. The pH scale ranges from 0 to 14, where a pH of 7 is considered neutral. Values below 7 indicate acidity, while values above 7 indicate alkalinity.

Alkaline soils typically contain a higher concentration of bases (such as calcium carbonate) compared to acids, which contributes to the higher pH level. Understanding soil pH is essential for agriculture and gardening, as it affects nutrient availability and biological activity within the soil, impacting plant growth and crop yield.

The categorization of pH levels helps in addressing agricultural practices and soil management effectively.
