Recently, some companies in Guangxi, Zhejiang, Jiangsu, Shandong, and Hebei produced a fertilizer called “sulfur-calcium fertilizer†and sold it in the agricultural resources market. Allegedly, this fertilizer contains phosphorus, sulfur, calcium and other elements, can increase the soil nutrient content. In this regard, experts from the China Phosphatic Fertilizer Industry Association pointed out that some manufacturers' false propaganda on the "sulfur and calcium fertilizer" fertilizer effect is purely a fraudulent peasant and misleading farmers to use fertilizer.
According to experts, "Sulfur-Calcium Fertilizer" is actually phosphogypsum, which is the solid waste in the production of phosphoric acid. The use of phosphogypsum as a "sulfur-calcium fertilizer" for crop growth requires no national standards. Phosphogypsum is generally applied only in alkaline soils with a pH of >9 (such as saline-alkali soil and a small number of soils along the beach) to regulate soil physical and chemical properties. However, the application of phosphogypsum in ordinary soil not only fails to provide sulfur fertilizer and calcium fertilizer as advertised by the manufacturer, but the extensive use of calcium sulphate (phosphogypsum) can also cause surface hardening of the soil and affect crop growth. Experts reminded distributors and farmers that phosphogypsum is not a fertilizer and can only be called a soil conditioner at best, and is not suitable for application in all soils. Experts reminded farmers that the symptoms of sulphur deficiency and calcium deficiency in soils in certain areas can be supplemented by the application of superphosphate. For the current market "sulfur calcium fertilizer" generally up to 200 yuan to 300 yuan per ton price, experts disclosed that as the production of solid waste of phosphoric acid, general ammonium phosphate business external sales will also be more than 10 yuan / ton, and even not money Baila, some manufacturers have to sell such a high price for packaging, which is purely profitable.
Recently, the China Phosphate Fertilizer Industry Association has officially stated that in order to purify the market environment and maintain a fair market order, it is hoped that the geological inspection, industry and commerce, and agricultural law enforcement brigade will strictly supervise and invite relevant departments to make more scientific propaganda. The vast numbers of farmers and distributors should improve their scientific identification capabilities. Do not rely on rumors and be deceived.
