CHLORIDE
No natural soil deficiencies of chloride are known to exist. Chloride-
containing fertilizers may lead to excessive or even toxic levels. A high
test reading, particularly where stunted growth has been observed, may
indicate poisoning due to high levels.
This test is valuable on saline soils or when contamination from sea
water or sea spray is suspected. Normal soils of humid regions rarely give
readable test results, except when liberal amounts of chloride-containing
fertilizers were recently applied.
Chloride is titrated with silver nitrate in *Chlorine Reagent 2S, after
potassium dichromate in *Chloride Reagent #1 has been added as an
indicator. The final result is read directly from the Titrator.
