Book Title: Doane Robinson's Encyclopedia Of South Dakota

  Alkali. This is the popular name for the mineral salts of the soil which are
found in varying quantities throughout the State. In some localities the soil is
so strongly impregnated as to injure and even defeat vegetation. When moisture
is abundant, and there is fair drainage, the alkalis do not appear to be
injurious; but in undrained basins in dry periods they render the soil
unproductive. They frequently cover the earth with a white efflorescence. An
analysis of some samples produced the following:

Sulphate of lime                    5.60
Sulphate of Soda                   43.40
Sulphate of ammonia and iron        3.25
Insoluble   matter                 44.00
Moisture and loss                   3.75

  Experience has proven that drainage of these alkali basins and thorough
cultivation, with the addition of humus, makes the earth especially productive.

Geo. Bul.,  I, 85.
