Composting is an environmentally friendly method to recycle organic waste into nutrient-rich soil amendments. One of the key factors in the fertilizer composting process is temperature. It greatly influences the rate of decomposition and the quality of the final product. Composting machines, whether small-scale for home use or large-scale for industrial fertilizer fermentation, is to control fertilizer composting temperature between 60°C to 70°C (140°F to 158°F).

Why the temperature is important for organic fertilizer making?

Composting microbial inoculant

As the name suggests, composting microbial inoculant is widely used in bio fertilizer composting process. It is beneficial for facilitating manure composting and eliminating the odor of animal manure. And commonly, this microbial agent is a kind of complex bacteria. Including photosynthetic bacteria, lactic acid bacteria, yeast, actinomycetes, penicillium, trichoderma, etc.

3 Main temperature phases in fertilizer composting

There are three main temperature phases in composting: the mesophilic, thermophilic, and maturation phases.

Cooling phase

After the thermophilic phase, the compost gradually cools down. And the fertilizer composting enters the maturation phase. Here, the temperature will slowly decrease and eventually stabilize near ambient temperatures. During maturation, the composting process slows, and the microorganisms work on refining the compost into a stable, humus-like material.

How to control the fertilizer fermentation temperature freely?

For large-scale manure disposal and organic fertilizer making operations, automated composting machines are invaluable. They can adjust aeration, moisture levels, and turning frequency based on temperature readings, maintaining an ideal environment for composting without constant human intervention. It is in-vessel fermentation tank.

What other items need to focus on for compost manure quickly?

In addition to monitoring temperature, composting machines facilitate airflow and moisture control, both of which are influential to the compost temperature. Adequate ventilation helps manage the temperature, preventing overheating, and ensuring even decomposition. Moisture levels also need to be optimal, as too much water can cool the compost and hinder aeration, while too little can impede microbial activity and halt the process.

In conclusion, temperature is a pivotal factor in the composting process, and composting machines are designed to foster the ideal thermal conditions for efficient organic waste decomposition. By understanding and controlling temperature, these machines can maximize compost quality, accelerate the composting process, and play a significant role in sustainable waste management.
