PURPOSE:To obtain an improved soil conditioning material containing aerobic bacterium, anaerobic bacterium, and metabolic products of them, by blending dung of domestic animals with anhydrous ferrous sulfate, piling the blend, reblending it, turning it upside down, decomposing and fermenting it. CONSTITUTION:Dung of domestic animals is blended with anhydrous ferrous sulfate in a weight ratio of preferably 1:0.2-0.5, piled, the piled material is reblended and turned upside down twice - three times, so that firstly occurrence and multiplication of aerobic bacteria are promoted. Then, after about 10-15 days, as anhydrous ferrous sulfate absorbs water in the dung of domestic animals, physical properties of the blend are changed, and aerobic bacteria occur and multiply. The period of this operation is about 10-15 days, and the blend is turned upside down twice - three times. When the water content reaches 30wt% and the specific gravity reaches about 0.7, fermentation heat is gradually lowered, and the blend is changed into soft odorless granules, to give the aimed soil conditioning material. EFFECT:Having antimicrobial action, sterilizing action, and natural enemy action on pathogenic germs of agricultural products, raising absorption ratio of nutrient and water of plants. |
