Abstract
Sulphur applied in the elemental form, or as sodium or calcium sulphate, on Grey Wooded soils, increased yields of alfalfa on sulphur-deficient Loon River loam, but not on sulphur-sufficient Garrick loam. The quantity of sulphate-sulphur was extremely low in the alfalfa grown on untreated Loon River loam and increased markedly as a result of the application of sulphur to the soil. Although herbage from untreated areas of the sulphur-deficient soil contained a slightly higher per cent nitrogen in 1955 than that grown on the sulphur-sufficient soil, sulphur treatment increased nitrogen content and yield of nitrogen on the sulphur-deficient soil. The relative abundance of nitrogen in the herbage grown on the check areas of the deficient soil suggests that the main effect of sulphur was not on root nodulation or nitrogen supply, but rather on nitrogen assimilation and other physiological functions of the sulphur-containing compounds within the plant.
