Bakken, Anne Kjersti Hansen, Sissel Strøm, Turid Steinshamn, Håvard Pasture and forage crops Farm nutrient management Feeding and growth 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. 2006 Conference paper, poster, etc. NonPeerReviewed source http://orgprints.org/7369/1/hansen_et_al_organic_congres_may_2006.doc Bakken, Anne Kjersti; Hansen, Sissel; Strøm, Turid and Steinshamn, Håvard (2006) Sulphur supply: a limiting factor in organic roughage-based livestock production?
