Sulfur fertilizer market of the future space

    Experts suggest that sulfur fertilizer into the soil testing and fertilizer
April 21, co-sponsored by the International Institute of sulfur, China Phosphate Fertilizer Industry Association and the China Sulfuric Acid Industry Association, China's sulfur fertilizer demand and fertilizer regulations international forum held in Beijing. Reporter was informed in the meeting, China's agricultural sulfur fertilizer demand has been gradually recognized by the parties, but the gap in the market still exists. Sulfur compound fertilizer is still one of the main direction of the fertilizer industry, the market with a bright future.
Chinese Soil Association data show that in 1985, about 30% of the soil sulfur deficiency, after 2005, some provinces data show that more than 60% of the soil with varying degrees of sulfur deficiency phenomenon, especially in northern China. Not only that, with the substantial reduction of atmospheric sulfur emissions, sulfur deficiency phenomenon exacerbated. International Institute of sulfur said Dr. Don Messick, the global sulfur fertilizer gap, at present, about 10 million tons, Asia, China and India, the most severe sulfur deficiency conditions.
     This reporter has learned, At present, the main varieties of sulfur fertilizer in China's market is still superphosphate, based NPK, etc., there are some other common varieties, such as magnesium, zinc production of potassium and magnesium sulfate, zinc sulfate, magnesium sulfate increase the number of sulfur fertilizer, some enterprises processing sulfuric acid exhaust byproduct ammonium sulfate, ammonium sulfite, as well as the relatively small production of sulfur-coated, sulfur-coated NPK.
China Sulfuric Acid Industry Association, vice chairman WU Xue - mei said that in recent years, China's apparent consumption of sulfur fertilizer showing an overall downward trend. According to statistics, from 2006 to 2012, the apparent consumption of sulfur fertilizer average annual decrease of 4.7%.
She said that the varieties of sulfur fertilizer in China is still the main superphosphate. But the in compound fertilizer development process, phosphate prices gradually move up, low grade transportation difficulties, lack of sulfur resources and other factors, accompanied by the development of high concentrations of phosphate and compound fertilizer, calcium superphosphate production year slow decline. 2012, single superphosphate production of 2.09 million tons (pure) were flat with the previous year, exports of 14.3 million tons, domestic apparent consumption of 1.947 million tons, about 174 million tons of elemental sulfur into the soil.
The second largest in the structure of China's sulfur fertilizer product is based NPK compound fertilizer. China Sulfuric Acid Industry Association statistics based NPK compound fertilizer production in recent years stabilized at 950 million to 10 million tons, into elemental sulfur is basically stable. 2012 based NPK production of 10.48 million tons and 1.15 million tons, into elemental sulfur. In 2012, the sulfur-compound fertilizer production provinces, including Shandong, Hubei, Guizhou.
    Sulfur fertilizer is ammonium sulfate. WU Xue - mei, 4:00 reasons, ammonium sulfate production increased year by year. First, caprolactam capacity growth; coking plant, power plant stockpiles to reduce gypsum by-product ammonium sulfate; sulfuric acid plant to meet emission standards, and also in the production of ammonium sulfate in the treatment of exhaust; Fourth, the comprehensive utilization of phosphogypsum . It is estimated that in 2012, China's agricultural ammonium sulfate apparent consumption of 164 million tons, about 39 million tons into elemental sulfur.
In addition, potassium sulfate sulfur fertilizer products, in 2012, the resource-based potassium sulfate production of 1.48 million tons, processing 860,000 tons of potassium sulfate production in 2012, the apparent consumption of 2.2 million tons of potassium sulfate into sulfur approximately 39 million tons.
In addition, phosphogypsum, TSP sulfur into the soil. According to incomplete statistics, in 2012 in Yunnan and other places phosphogypsum to do the amount of soil conditioner to reach 1.5 million tons, about 24 million tons of sulfur into the soil. The amount of TSP in the country has remained at 10 million tons, less than 1 million tons of sulfur into the.
    WU Xue - mei future with the improvement of the quality of crops, sulfur-deficient areas will increase by S fertilization of sulfur fertilizer production will show a slow growth. Expected to the 2015 sulfur fertilizer production will be restored to 430 million tons, sulfur fertilizer in 2012 and 2015, the annual growth rate up to 5.3%.
    In this process, calcium superphosphate production will enter a stable stage. Due to the high concentrations of phosphate and compound fertilizer development advantages, it is expected that in the next few years, the low concentration of calcium superphosphate basic maintained at 200 million tons, or declining, but is still the main varieties of sulfur fertilizer. In addition, ammonium sulfate could increase significantly. The reason, the environmental protection department proposed more stringent requirements on sulfur dioxide emissions, power plants, coking plants, steel mills use more ammonia recovery of by-product ammonium sulfate; more sulfuric acid plant recovery of ammonia to produce ammonium sulfate; comprehensive utilization of phosphogypsum.
    The participating experts predict that the future of superphosphate, based NPK production will stabilize at current levels, which will ensure the stability of the sulfur fertilizer production in the next few years. In addition, Xinjiang, Qinghai, potassium sulfate, potassium sulfate, magnesium may become a new growth point in the future sulfur fertilizer industry. Sulfur clothing urea, sulfur clothing, NPK sulfur into the low-cost area, there will be some room for development. Finally, a new sulfur-based fertilizer - ammonium thiosulfate as a liquid fertilizer will gradually be accepted by the market. Based on these points, the experts said, China's sulfur fertilizer industry in the "five", "13 5" during the slow growth.
    In order to make the sulfur healthy development of the fertilizer industry, to develop a broader market, the experts recommended that countries can formulate relevant policies to be reflected in the value of sulfur in the sulfur-containing fertilizers, improve the production of sulfur fertilizer enthusiasm: an increase in the revised standards for sulfur fertilizer sulfur content provisions, and gradually strengthen the dynamic monitoring of soil sulfur deficiency sulfur fertilizer into the soil testing and fertilizer work. In addition, enterprises and research institutes should strengthen the publicity and guidance for farmers to use sulfur fertilizer.
