Sulphur and Sustainable Agriculture

The sulphur-containing amino acids methionine and cystine are essential for production of proteins; without them and other sulphur-containing materials, there would be no life as we know it. Increasing crop yields and the move to ‘high-analysis’ fertilizers that contain little sulphur has lead to increasing sulphur deficiencies, which must be urgently overcome to sustain agro-ecosystems. This timely publication brings together the many aspects of sulphur in agriculture, looking at both crop and livestock production. It discusses the importance of sulphur cycling and the essential role of sulphur fertilization. It also suggests recommendations for better managing sulphur and ensuring sustainability of agricultural systems.
