Nitrogen and sulfur mineralization of several Manitoba soils and N:S ratios in rape and barley
A field experiment, conducted in the summer of 1967, disclosed that total N:S ratios of plants in the early stages of growth can be used to evaluate their sulfur status. The critical ratios above which rape and barley are sulfur deficient were suggested to be 12:1 and 16:1, respectively. The cr...
