A rapid method for determining total S in plants by X‐ray fluorescence spectro‐metric analysis of ground pelletised plant material is compared with chemical methods using titrimetric, flame photometric and turbidimetric methods of sulphate determination. Errors in the chemical methods were caused by incomplete oxidation of organic sulphur and by non‐reproducibility of the turbidimetric determination of sulphate. A method incorporating the oxidation of the sample with HNO3 and Mg(NO3)2 and titration of the reduced sulphate by mercuric acetate gave recoveries accurate to a mean of 1% when determining the sulphur content of sulphur compounds.
