Slaked lime, purchasable in either ground or fine-grained form, is frequently proposed to raise pH degrees. Ground limestone is the slenderly less powerful of the two and grows pH more tardily. The quantity necessitated hinges upon the soil texture (more is demanded for clay than for sandlike soil, for instance).

Alkalic soils frequently occur in waterless areas that receive less than 25 ins of rainwater per annum. The majority of the soils western of the Missouri River are alkalic. Numerous plants popular for water-wise gardens do well in alkalic soil. The European olive tree, native to the Mediterranean Sea basin, is one illustration of a plant that flourishes in alkalic soil; lilac and pomegranate tree as well perform well.
