Correct application methods for sulfur nutrition in rapeseed

(Agricultural Wealth Network) The simplest method is to apply other fertilizers that contain sulfur, achieving two goals at once. For example, on sulfur-deficient soil, use ammonium sulfate when applying nitrogen fertilizer, use superphosphate when applying phosphate fertilizer, and use potassium sulfate when applying potassium fertilizer. Most soils in China are not sulfur-deficient, and under normal circumstances, no dedicated sulfur fertilizer is needed. According to surveys, only some soils in Zhejiang, Jiangxi, Fujian, Anhui and other provinces south of the Yangtze River are sulfur-deficient and require sulfur fertilizer application. Gypsum and sulfur can also be applied as sulfur fertilizer.
