Sulphur is a critical plant nutrient which often gets forgotten by our narrow emphasis on NPK. Many Irish soils are deficient in Sulphur yet having adequate amounts is important for nitrogen use efficiency and will have a big impact on yield and quality. Plants which have a high sulphur requirement include oilseed rape, brassicas, onions, leeks as well as grassland. The main symptom of S deficiency is a leaf yellowing similar to that of N deficiency but with younger leaves suffering more.
