Correct Application of sulfur Nutrition in rapeseed

The easiest way is to use other fertilizers containing sulfur, which can kill two birds with one stone. For example, in the sulfur-deficient soil, ammonium sulfate is used when applying nitrogen fertilizer and calcium superphosphate is used when applying potassium fertilizer. Most of the soils in China are not short of sulfur, and in general, there is no need to apply special sulfur fertilizer. According to the survey, only some soils in Zhejiang, Jiangxi, Fujian, Anhui and other provinces in the south of the Yangtze River are deficient in sulfur and need to apply sulfur fertilizer.
