Sulphur supply: a limiting factor in organic roughage-based livestock production?

Abstract - The herbage sulphur (S) content on 28 organic farms was monitored in order to evaluate the S supply for plants and ruminants in organic livestock production. The S content and the protein content were generally low. S fertilisation improved the yield and protein content of red clover only when the initial S supply was very low. Increasing S application rates did not increase the S content of red clover above a certain level that depended on other soil and environmental factors. Instead of an increase in the shoots with increasing S supply, there was an accumulation of S in the roots.
