Having the reactions of an alkali.
In our context, a substance having a pH above that of neutral water (7.0) when in solution. Signified as pH (potential of Hydrogen), alkaline fluids, such as the blood, have the ability to neutralize acids. metabolic wastes are acids, and the alkaline reserve of the blood neutralizes them until they are excreted.
Containing a great deal of calcium (lime) to give a pH reaction of more than 7. It is the sort of soil preferred by such plants as bearded irises and the cabbage tribe, and in which hydrangeas flower pmk. Some gardeners refer to alkaline soils as “sweet.”
