Bio Fertilizer Manufacturing

Bio organic fertilizer refers to a type of fertilizer that has the effects of both microbial fertilizer and organic fertilizer, which is a compound of specific functional microorganisms and organic materials that are mainly derived from animal and plant residues (such as livestock and poultry manure, crop straw, etc.) and have been harmlessly treated and decomposed.


Biofertilizer raw materials

There are many raw materials for the production of bio-organic fertilizers, which can be specifically divided into the following categories:

coconut shell
corn stalks
urban sludge
rice husk
Pennisetum purpureum
palm kernel shell
  1. Urban sludge: river sludge, sewer sludge, etc.;
  2. Agricultural waste: straw, soybean meal, cottonseed meal, rapeseed cake, etc.;
  3. Livestock and poultry manure: chicken manure, cattle, sheep and horse manure, rabbit manure;
  4. Industrial waste: wine lees, vinegar lees, cassava residue, sugar residue, furfural residue, sawdust, etc.;
  5. Domestic waste: kitchen waste, vegetable market waste, etc.;
  6. Plant products: bamboo powder, bamboo charcoal, bamboo ash, straw charcoal, plant ash, etc.

Benefits of Bio Organic Fertilizer

  • Improve crop yield and quality: Provide comprehensive nutrition, including basic elements such as nitrogen, phosphorus, potassium and various trace elements, promote healthy growth of crops, and improve yield and quality.
  • Reduce pollution: Organic fertilizers generally contain less salt than chemical synthetic fertilizers. Therefore, they can reduce nitrate pollution and require less water to dilute fertilizers.
  • Improve soil structure: Increase the organic matter content of the soil, improve the physical structure of the soil, and enhance the water retention and air permeability of the soil.
  • Price advantage: The raw materials of biological organic fertilizers mainly come from organic and biodegradable solid wastes, such as pig manure, chicken manure, kitchen waste, urban domestic waste, etc. Therefore, they have a great price advantage.

When planning and building a bio-organic fertilizer plant, we recommend precisely adjusting the production scale according to local resources, market capacity and coverage. In general, annual production capacity is usually between 30,000 and 250,000 tons. For a new small-scale plant, the optimal output we recommend may be around 10,000 tons (1.5 tons per hour), 20,000 tons (3 tons per hour) or 30,000 tons (4.5 tons per hour). The annual output of a medium-sized plant is usually between 50,000 and 100,000 tons, while large facilities can reach an output of 100,000 to 300,000 tons.

When determining the investment scale and designing the product plan, key factors such as raw material characteristics, local soil conditions, major crop types, site conditions and automation level are considered. These factors not only ensure production efficiency, but also meet the specific needs of agricultural practices, thereby promoting sustainable development and occupying a favorable position in a highly competitive market.

How to Make Bio Organic Fertilizer?

The production of bio-fertilizers involves the use of natural organic materials such as animal and plant residues, and manure, which are transformed into nutrient-rich fertilizers through microbial decomposition. The process typically includes steps like raw material collection, composting fermentation, microbial inoculation, and final product packaging. 

During the raw material collection phase, selecting high-quality organic materials is crucial as proper treatment enhances the fertilizer’s nutrient content. Effective composting fermentation, controlled by appropriate moisture, oxygen, and temperature levels, is critical for stimulating microbial activity and accelerating organic matter decomposition. Inoculating suitable microbial strains such as nitrogen-fixing, phosphate-solubilizing, and enzyme-producing bacteria significantly enhances nutrient release efficiency. Finally, stringent testing and packaging ensure that the produced bio-fertilizers meet standards and maintain long-term stability, thereby promoting sustainable agricultural production and the health of soil ecosystems.

Features of Bio Organic Fertilizer Production Line

Bio-organic fertilizer projects have many advantages:

  • The construction period of bio-organic fertilizer projects is usually short, which is conducive to rapid production and rapid response to market demand. By adopting the latest special equipment and technology, organic fertilizer production technology can efficiently process a variety of organic wastes, including livestock manure on farms, organic waste from plants, agricultural waste, sludge, etc.
  • The production process of bio-organic fertilizer focuses on green environmental protection. Through biotechnology and advanced processes, these wastes are converted into fertilizers rich in organic matter and nutrients, which can not only effectively improve soil quality and structure, but also reduce environmental pollution and greenhouse gas emissions.
  • Investing in bio-organic fertilizer projects has a high rate of return and low risk. With the increase in consumer demand for healthy food and environmentally friendly products, the market for organic agricultural products continues to expand, providing broad market prospects and development space for bio-organic fertilizers. Investors are usually able to quickly realize a return on investment in the short term and enjoy a shorter payback period.

Notes on The Production Process of Biofertilizers

Small organic fertilizer production line01
  1. Raw material selection and processing: Microbial strains are the core of biofertilizers. Different microorganisms have different functions, so you need to choose functional microorganisms according to your biofertilizer. Generally speaking, the microorganisms you choose should have good high temperature resistance and high survival rate. Make sure the raw materials are free of contaminants and are properly processed, such as shredded or piled, to promote effective decomposition and fermentation processes.
  2. Composting fermentation conditions: Maintaining proper humidity, oxygen and temperature is key to ensuring microbial activity and decomposition of organic matter. Too high or too low temperature, humidity or lack of oxygen may affect the quality and speed of composting.
  3. Quality control and testing: Strict quality control and testing are carried out throughout the production process, including raw material inspection, fermentation process monitoring, strain activity testing, and final product analysis to ensure that the produced biofertilizer meets standards and quality requirements.
  4. Production equipment: It will affect the quality of fertilizers. If high-quality equipment is used, the damage to the raw materials is relatively small. In this way, you can get high-quality biofertilizers.
  5. Packaging and storage: Choose appropriate packaging materials and methods to ensure that the biofertilizer is not affected by pollution and humidity during transportation and storage, and maintain long-term stability and effectiveness.
