Differences between Organic Fertilizer Production and Bioorganic Fertilizer Production


Organic fertilizer is mainly derived from plants or animals, and carbon materials are applied to the soil to provide plant nutrition as its main function. Bio-organic fertilizer refers to a kind of fertilizer with both microbial fertilizer and organic fertilizer effects, which is composed of specific functional microorganisms and organic materials, mainly from animal and plant residues (such as animal manure, crop straw, etc.) and which are treated harmlessly and matured.
Bio-organic Fertilizer Production
Fermented organic fertilizers were used as carriers. The bio organic fertilizer processed by adding probiotics refers to a kind of specific organic fertilizer containing the microorganisms beneficial to the growth of crops. It has the function of both microbial fertilizer and organic fertilizer. Bio-organic fertilizer is suitable for all kinds of soil and crops, and has considerable fertilizer effect.
Bio-organic fertilizer is a kind of complete fertilizer. It is rich in organic matter. It not only contains a lot of elements such as nitrogen, phosphorus and potassium, but also contains trace elements such as calcium, magnesium, sulfur, iron, manganese, zinc, copper, boron, molybdenum and chlorine. Functional bacteria in bio-organic fertilizer can decompose mineral phosphorus in soil, mineral potassium in soil, release phosphorus, potassium and other nutrients. Enduring nutrients to crops. From the use effect for many years, the fertilizer efficiency of bio-organic fertilizer has been verified on various crops and achieved satisfactory results. It has been recognized by the vast number of farmers. 
Organic Fertilizer Production
When used as raw materials such as crop straw for fermentation, about 20% livestock and poultry manure can be added. When using livestock and poultry manure as raw materials, about 20% straw powder can be added. After 24 hours, the temperature in the compost can reach about 50℃, and 48 hours, the temperature can rise to about 70℃. The compost turning equipment can be fully oxygenated, fermented evenly, and some water can be discharged to achieve harmless and resource utilization. After several days of continuous high temperature, the heap temperature gradually decreased, about two weeks later, the raw materials after fermentation were all decomposed, the eggs, grass seeds and pathogenic bacteria in the raw materials were all killed, and the straw turned brown or black brown. If fermentation is carried out with more acidic raw materials, about 1-3% lime powder should be added during fermentation to adjust the acidity to neutrality. The organic fertilizer fermented by this method is suitable for all kinds of crops and soils. It can be used for its own use or processed into commercial fertilizer for sale.
Fertilizer Granulation
The granulation methods of organic fertilizer and bio-organic fertilizer are basically the same. According to the requirements of production technology, there are two kinds of granulation methods commonly used in fertilizer production line: disc granulation and rotary drum granulation. Due to the different requirements of raw materials for different granulation methods, there are differences in the production process of organic fertilizer.
In the process of disc granulation, the raw materials need to be desiccated after a certain amount of water is removed, broken, and then mixed evenly with inorganic fertilizer after adding a certain amount of acid-base adjusting carrier pH, and sent to the disc granulator. A certain amount of bacterial agent is sprayed into the granulating process, and the granulated products are then dried and sifted at low temperature, and the finished products can be obtained.
Rotary drum granulation is a process of continuous mixing, granulation, spheroidization and densification of fine powder in the machine by using the mechanical stirring force of high-speed rotation and the resulting aerodynamic force, so as to achieve the purpose of granulation. The particle shape is spherical and the granulation rate is more than 90%. The size of particle diameter can be adjusted properly by mixing amount of material and spindle speed. Usually, the lower the mixing amount, the higher the speed, the smaller the particle, and vice versa.
