How much sulphur do plants need?
Most crops remove 15 to 30 kg for sulphur per hectare (S/ha). Oil crops, legumes, forages, and some vegetables require more sulphur than phosphorus for optimal yield and quality. Plants contain as much sulphur as phosphorus, with an average content of approximately 0.25%. Usual recommendations for correcting deficiency are 15 to 30 kg S/ha for cereal crops and silage grass; and 25 to 50 kg S/ha for oil crops, legume, sugarcane, and some vegetable crops. For more detailed information about sulphur demand for specific crops and regions, please see The Sulphur Institute’s Publications.
