The soil reaction is generally understood to mean the acid- or. Lime content of the soil.

The cultivated soil can be acidic, be neutral or alkaline. The soil reaction is measurable and is expressed in pH numbers. In practice, pH 6.5-7.3 is considered neutral, pH 4,6-6,4 as weakly acidic to acidic and below as strongly acidic. pH 7.4-8.0 is slightly alkaline and pH 8.0-8.5 alkaline. As long as the vegetable land has about 0.3-0.5% carbonate of lime, the soil cannot acidify.
