SULFUR
Sulfur is essential to the formation of protein, and affects various aspects
of plant metabolism. Plants which are deficient in sulfur can be
distinguished by the pale green color and thin, reedy stems. The major
sources of sulfur are fertilizers containing sulfate compounds, and
atmospheric sulfur dioxide carried into the soil by precipitation.
*Sulfate Reagent contains barium chloride, which reacts with sulfur to
form a barium sulfate precipitate. The resulting turbidity is matched to a
standard to determine the sulfur concentration.
