Circumneutral is a descriptor for soils which have a pH that is close to neutral. Circumneutral soils have a pH between 6.5 and 7.5. [1] A soil’s pH affects whether minerals dissolve in the soil and how quickly they dissolve. This causes circumneutral soils to have unique chemical qualities. [2]

In the early 1870s a consulting chemist to the Royal Agricultural Society in England, named J. Thomas Way, performed many experiments on how soils exchange ions, and is considered the father of soil chemistry. [1]
