The fact that sulphur is an essential element for the growth of all plants points out the importance of sulphur studies in soils. It has been shown that sulphur is needed in amounts of the same order as phosphorus, even greater sometimes, by most crops. An investigation of the sulphur status of Quebec soils was initiated at Macdonald College in 1957. Particular attention was paid to the methods of total sulphur and sulphate determination. It was concluded (58) that no signs of deficiency seemed to occur in these soils. The distribution of sulphur in soil profiles has been studied by various workers (30, 70, 74). Relatively high sulphate contents in subsoils have been found (30) and the availability of this sulphur to plants was demonstrated.
