Sulphur and protein were determined on the grain of two varieties of spring wheat, grown at twelve stations in the province of British Columbia. The stations, in representing the principal agricultural areas of the Province, also presented a broad latitudinal array of soil and climatic types. The average sulphur, ranged from a high of .226% at one station to a low of .151% at another station; the protein content ranged from 17.6% to 9.4%. Nowhere were the levels of sulphur so low that support was obtained for the belief that wheat production might be limited by its deficiency. The protein content followed expected trends in response to changes in soil and climate. A highly significant correlation, +.76, was found to exist between total sulphur and protein of the wheat. The selenium problem is in review, and a method is outlined for the selenium assay of British Columbia wheat. / Land and Food Systems, Faculty of / Graduate
