Biofertilizer composting can improve resource utilization and reduce soil improvement costs. Temperature, oxygen and humidity are the main factors affecting bio fertilizer composting. To promote the decomposition of organic matter, you can add appropriate amounts of bacteria, such as aerobic fermentation agent and quality azotobacter. Moreover, in the process of making bio organic fertilizer, you can use a biofertilizer  composting machine to speed up fermentation time. YUSHUNXIN has a variety of fermentation composting equipment with different output and performance, you can choose the right one through consultation.

What Are the Best Raw Materials for Composting Biofertilizer?

Choosing the right raw materials is the first step to making high-quality biofertilizer. Many types of organic waste can be composted—from animal manure to crop residues. Each material has its own characteristics, and understanding them helps you select the right composting method and equipment.

Cow dung, chicken manure, pig manure, and sheep dung are rich in nitrogen and beneficial microbes. They compost well but often need to be mixed with dry materials like sawdust or straw to balance moisture and carbon levels.

Straw, corn stalks, peanut shells, and other plant-based residues are high in carbon but low in nitrogen. They require nitrogen-rich additives (like manure) and sometimes crushing to speed up decomposition.

Leftover from biogas plants, digestate contains partially decomposed organic matter and nutrients. It is semi-fermented and ideal for further aerobic composting to stabilize and enrich it.

High in moisture and easy to rot, kitchen waste needs careful control of water content and aeration. It’s best composted with dry bulking agents like sawdust or dry leaves.
Materials like oilseed cakes, mushroom residue, and fruit peels can also be composted. These often add specific nutrients to the final biofertilizer.

How to Speed Up Biofertilizer Composting?

Use Efficient Composting Equipment:

To shorten composting time, it is essential for you to use an advanced composting machine. It can accelerate the fermentation process by ensuring proper aeration, temperature, and material mixing. We can recommend a suitable composting machine for you according to your capacity, budget, and specific needs. Welcome to consult us!

Add Composting Microbial Strains: 

Adding microbial fermentation agents can dramatically boost the composting process. These microbes (e.g., Bacillus, yeast, actinomycetes) help decompose organic matter faster and reduce odor. Different materials require different microbial strains for optimal results.

  • Thermophilic bacteria are ideal for cow dung.
  • Cellulose-degrading fungi work well with straw.

  • Mixed aerobic bacteria are suitable for food waste.

These agents can be added directly into the compost pile or during the raw material mixing stage to ensure even distribution and effective fermentation.

Optimize Composting Conditions:

Fast composting requires maintaining an ideal fermentation environment. To achieve this, you should keep the carbon-to-nitrogen (C/N) ratio between 25:1 and 30:1, ensure the moisture content stays around 50–60%, and turn the materials regularly to provide enough oxygen. Additionally, maintaining the temperature at 50–65°C during the thermophilic phase is essential to promote microbial activity and accelerate decomposition.

How Many Types of Commercial Composting Machines Can Be Used to Compost Biofertilizer?

There are several types of commercial composting machines available for biofertilizer production in YUSHUNXIN. Each suits different composting needs and scales. Below are three common options:

Biofertilizer Fermenter – High Fermentation Speed

If you need to ferment organic waste in a short time, the organic fermentation tank is a reliable option. It handles a wide range of raw materials and uses high-temperature aerobic fermentation to rapidly and safely decompose organic matter. The closed design minimizes odors and operates independently of external temperatures. Fermentation is typically completed within 7–15 days. YUSHUNXIN offers fermentation tanks ranging from 5 to 150 m³ and provides customized solutions. Contact us for more details!

Windrow Composting Turner – Mobile Composter

Looking for mobile composting equipment for your farm? Consider the windrow compost turner. Both crawler-type and self-propelled composters come with flexible mobility systems and simple controls. You can easily move them forward, backward, or turn them on flat ground. This equipment is ideal for indoor and outdoor composting—just pile your organic waste into long windrows.

Trench Composting Equipment – For Small and Large Systems

The trench compost turner is ideal for both small-scale and large-scale biofertilizer production. It turns organic waste in composting channels to accelerate decomposition. The wheel-type trench turner features a turning span of 8 to 30 meters and a depth of 1 to 3 meters, making it a great option for industrial-scale composting. For smaller operations, we also offer compact trench turners and chain plate composters. Contact us to find the right model for your composting needs.

How to Further Turn Mature Compost into High-Quality Biofertilizer?

Use a compost crusher to break fermented compost into fine, uniform powder. This improves consistency, enhances nutrient distribution, and prepares the material for screening and packaging. Fine powder is ideal for producing high-quality powdery biofertilizer.

Then, you can use a drum screening machine to remove impurities like plastic, stones, and large fibers from crushed compost. Screening improves product purity and protects downstream equipment, ensuring a clean, market-ready powder biofertilizer.

Use an automatic bagging machine to pack screened compost into bags. This improves efficiency, ensures consistent weight, and extends shelf life. Proper packaging helps deliver high-quality powdery biofertilizer to the market.

Which Microbial Strains Should You Add During Composting?

Choosing the right microbial agents is key to effective composting.

Aerobic fermentation agent

First, you should evaluate your raw materials. For example, if your compost contains a high amount of livestock manure, adding thermophilic bacteria helps accelerate organic matter breakdown during the high-temperature phase. If your feedstock is rich in carbon (like straw or husks), cellulose-degrading bacteria will improve compost maturity.

Then, you can also add nitrogen-fixing or phosphate-solubilizing bacteria to enhance the nutrient content of the final compost. In areas with high salinity or poor soil structure, functional strains like Bacillus subtilis or Pseudomonas fluorescens can improve biofertilizer performance.
