General stage devision
The small scale organic fertilizer composting generally can be devided into two stages, namely the first high-temperature compost decomposed fermentation stage and the second aging stage. During this process, the unstable organic matter is transformed into stable humus through the decomposing process and under the action of microorganisms. Here, SX can provide you with high quality equipment for samll scale fertilizer fermentation
Let’s talk about the first stage : by proportioning the raw material matrix, the compost will absorb high oxygen, generate high temperature, greatly reduce the degradable volatile solids, gradually reduce the odor, and gradually change the color of the compost pile, and it is necessary to maintain good aeration and moisture control. .
Secondary composting of samll scale composting : The temperature initially decreased, the oxygen absorption rate decreased, and the odor completely disappeared.
Compared with the first compost, the second compost cannot be used without the second compost, because the second compost can degrade the refractory organic matter, and the mesophilic microbial colony can be re-established, thereby helping the organic fertilizer to decompose, reducing phytotoxic substances and inhibiting pathogenic bacteria.

Ddeviding from temperature changing
The temperature change of organic fertilizer can define whether it is decomposed or not.
Temperature rising stage:
The decomposing temperature of organic fertilizer rises to 45℃, mainly actinomycetes, fungi and bacteria, mainly decompose sugars and starches. Even active biological animals and animals are involved.
High temperature stage:
The decomposing temperature reaches above 45°C, mesophilic microorganisms are inhibited, and thermophilicity dominates. Soluble organic matter continues to be decomposed by oxidation, and complex organic matter (cellulose, hemicellulose, protein, lignin) also begins to be decomposed. Around 50°C (thermophilic fungi and actinomycetes); around 60°C (thermophilic bacteria and actinomycetes); around 70°C (most microorganisms have been unable to adapt).
The optimum temperature for decomposing is 55°C, because most microorganisms are most active at this temperature and are most likely to decompose organic matter, and most of the germs, eggs and weed seeds will be killed.

Temperature falling stage:
Mesophilic microorganisms start to multiply again, take the lead, and further decompose the remaining refractory organic matter. At this time, the activity of microorganisms decreased, the oxygen demand of the compost to decompose decreased, the temperature decreased, and the compost gradually became stable.
