摘要:

An automated soil test for sulphur and interpretative criteria for Saskatchewan conditions are presented. Sulphate‐sulphur (SO4‐S) in 0.01 M CaCl2extracts of soil is determined by turbidimetric and nephelometric procedures operating simultaneously in an AutoAnalyzer system. A procedure for the segregation and elimination of samples containing excessive amounts of SO4‐S is described.
