ALUMINUM
All soils contain significant concentrations of aluminum, in the form of
inorganic colloidal material and undecomposed minerals. In neutral,
slightly alkaline, or slightly acid soils the aluminum is in inert
combinations that do not affect plant growth. In more acidic soils,
aluminum can form potentially toxic salts. A high test result indicates an
undesirable acid soil. Plants which normally thrive on acid soils may fail
in a soil with a high active aluminum test reading. A medium test result
is tolerable to many plants, including grasses, corn, oats, potatoes, and
tobacco; a low or negative aluminum result is preferable.
Aluminum reacts with hematein in the *Aluminum Test Solution to
form a colored solution. The resulting color is matched to a color chart
to determine the aluminum concentration.
