Production technology of bio organic fertilizer and factors affecting safety


We often use bio organic fertilizer in agricultural planting, and organic waste is its processing raw material. Chicken manure and crop straw as the main raw materials, after fermentation, they are further made into high-quality organic fertilizer products by disc granulator machine. The fermentation process can decompose chemical pesticide and chemical fertilizer residues, improve fertilizer quality and increase fertilizer disease resistance.

Bio organic fertilizer is rich in nutrients, which can improve the soil and improve the soil consolidation caused by the application of chemical fertilizer. Improve the physical and chemical properties of soil, enhance the ability of soil water conservation and fertilization. According to the scale of bio organic fertilizer production line, the production process can be divided into flat composting and tank fermentation.

The factors affecting the safety of bio organic fertilizer are as follows

1、 Organic pollutants: these pollutants come from sludge, crop straw, etc.

2、 Antibiotics, organic arsenic: This is extracted from a variety of antibiotics widely used in animal husbandry, most of which are excreted with feces and urine in the original form of drugs. Pig manure, chicken manure and other livestock wastes are widely used in agricultural production as raw materials of bio organic fertilizer. The amount of antibiotics entering the soil every year is no less than that of pesticides, and enters the food chain through soil fertilizer. Some veterinary drugs are more toxic to the metabolites excreted in feces.

3、 Heavy metal pollution: the main pollution sources are mineral raw materials for production, smelting waste acid, heavy metal contaminated sludge, etc. Heavy metal pollution is common in phosphate fertilizer products and compound fertilizer products. In addition, the content of inorganic impurities such as salt in some chemical fertilizers is too high, which will not only cause soil salinization, but also cause seedling burning or yield reduction.

4、 Another type is pathogens and eggs, which are derived from untested microbial strains and can cause infection in humans or animals. Unsafe factors in the use of strains are also gradually expanding, and strains harmful to humans, animals and plants may flow into production. Some conditional strains may flow into the production chain, resulting in safety problems.

In order to ensure the quality of organic fertilizer, in the production process of bio organic fertilizer, it is necessary to ensure that the organic fertilizer is fully decomposed by high temperature fermentation. The raw materials are processed according to the production process. We provide a complete set of organic fertilizer production line equipment and other fertilizer machines, including roller granulator, flat die pellet mill, organic fertilizer granulator, dryer, crusher, screening machine, etc.
