Summary A description is given of methods for determining quantitatively the total sulphur, oxidizable sulphur, monosulphidic sulphur, and extractable sulphur (free and organically bound) in soil. Monosulphidic sulphur is determined by boiling the soil sample with hydrochloric acid and distilling the liberated hydrogen sulphide with a nitrogen current into a cadmium acetate solution, after which the cadmium sulphide precipitate is determined iodometrically. Oxidizable sulphur is determined in a similar way by exposing the sample to tin and concentrated hydrochloric acid. Total sulphur is also determined via hydrogen sulphide, obtained in this case by ignition of the sample withferrum reductum in a nitrogen current and liberation of hydrogen sulphide with hydrochloric acid. For determining extractable sulphur, acetone is recommanded.
