Factors in biological organic fertilizer fermentation process
2020-01-21
The products produced by the biofertilizer project process use fresh chicken and pig manure as raw materials and do not contain any chemical ingredients. However, chicken and pigs have poor digestion ability and can only consume 25% of the nutritional ingredients. Feces are excreted, so that the dried product contains nitrogen, phosphorus, potassium, organic matter, amino acids, proteins and other ingredients.
(1) In the production process of biofertilizer project, it is necessary to effectively control the factors that affect the fermentation of organic waste and the reproduction of microorganisms. The main influencing factors are organic matter content, water content, carbon-nitrogen ratio, oxygen concentration and temperature during composting, and PH value. On the one hand, through the control of various factors, the carbon-nitrogen ratio, temperature, humidity, pH value, oxygen amount and other nutrients necessary for the growth and reproduction of each microbial species are satisfied; on the other hand, different nutrient content can produce Fertilizer effects with different effects, such as high carbon content helps soil fungi increase, nitrogen helps soil bacteria increase, and calcium has a significant effect on crop disease resistance.
(2) The malodor produced by compost needs to be prevented and controlled to avoid secondary pollution. Adding a starter to the pile or using a compost turner machine to turn over can reduce the odor in a short period of time, and the sensory effect is good; or the malodorous gas produced in the compost yard is treated with biological deodorization technology.
(3) Strictly control the content of heavy metals in raw materials to prevent microbial poisoning in the later production process and excessive levels of heavy metals in finished organic fertilizers, which will pollute the soil and crops.
(4) After analysis and testing of the finished product, the content of organic matter, humic acid, nitrogen, phosphorus, potassium and other trace elements, and the number of live bacteria should meet or exceed national standards.
