Shandong Duoyicheng Fertilizer Technology Co., Ltd. is located in Linyi national economic and technical development zone. It is ten kilometers from the Linyi Airport, close to Lianyungang port and Qingdao port, with very convenient transportation. The company has a 20000 square meters’ standard workshop, mainly produces the polymer coated fertilizer, bulk blending fertilizer, water soluble fertilizer, etc. The micron sized polymer coating technology in environmental protection, with the national patent application number 201310428963.7, is used in polymer coated fertilizer. The technology represents the leading position of solvent free reaction insitu coating technology. Through filming a micron thickness coating on granular fertilizer, the polymer coating has the function of low initial release rate and the release process only depends on soil temperature and moisture. The timing curve of nutrient release just like “S” shape, the same requirement for crop growth. Through scientific calculation, we owned the formula of bulk blending fertilizer. With the microelements and additional nutrients in it, the BB. fertilizer has the characteristics of controlled diffusing, high water solubility, low salt, high safety, composition of multi elements. Compare with other similar products, the BB. fertilizer has big advantages. It increases the crops yields in case of reducing the fertilizer usage, and it will be the substitute for the common chemical fertilizer, known as a kind of nice fertilizer for soil improvement and environmental protecting in 21st century.
