Cooperating  with research institutions, Hebei Jintu Biological Technology Co., Ltd takes  advantage of biological fermentation technology to produce mid-to-high-end  bio-functional fertilizer. The raw materials are agriculture and forestry  wastes, such as livestock  corpses and manure, crop shells and straw, carbonized fruit tree, waste  cake from food munufacturing factory and so on. The fertilizer has functions of improving soil structure, improving crop quality and increasing yield capacity,  degrading poisonous and harmful substances,  reducingthe outbreaks  of diseases, grass and pest, which has a positive role in promoting  agricultural sustainable development and food safety demonstration. Using  special bacteria, the project mixes the dead animal with organic waste  directly to produce the raw material of animal protein fertilizer in 10 days  without secondary pollution.    At present, it has invested 59 million yuan to build a larger biological  fertilizer production base in north China. Cooperating with the microbiology  institute of Chinese Academy of Sciences, Huazhong Agricultural University  and the University of Tennessee, it has developed its research team,  collected and preserved thousands of agricultural microorganism resources which has become a precious wealth.
