How To Control The Temperature In Organic Fertilizer Compost

The temperature, humidity, PH value and C/N ratio of the compost during the fermentation process are important factors affecting the effect of the compost. The temperature during the fermentation process of organic fertilizer can be summarized as follows: the temperature rises steadily in the early stage, the high temperature in the middle part remains moderate, and the temperature decreases slowly in the later stage, and the temperature control directly affects the maturity of organic fertilizer in the later stage.

Today, mainly explain how to control the temperature in the organic fertilizer fermentation

The compost temperature of organic fertilizers is mainly controlled by pile turning and forced ventilation. Here, SX can provide you with processional compost turner. In the early stage of fermentation, even if the temperature of the fermentation is slow or even does not rise, the pile must be turned or ventilated after 48 hours to avoid the formation of an anaerobic environment in the high temperature stage. When the pile temperature is lower than 50°C, the pile should be turned in time (the reduction of oxygen will cause the reaction in the pile to gradually decrease, thereby reducing the temperature), increase the pile temperature, promote the decomposition of organic matter and kill harmful microorganisms. In the late stage of fermentation, once the temperature exceeds 65°C, The pile must be turned in time to prevent carbonization and ammoniation of organic matter. Click here to learn more.

During aerobic fermentation, temperature control is very important. If the temperature is too low, the maturity standard will not be met. If the temperature is too high, the nutrients in the compost will be easily lost. The temperature in the compost is within 30 cm from the outside to the inside. Therefore, the metal rod of the thermometer used to measure the temperature must be longer than 30 cm. When measuring, it must be inserted into the compost for more than 30 cm to correctly reflect the fermentation temperature of the compost. In SX, we also have compost machine with temperature monitor on sale, It is in-vessel fermentation tank.

How to read the compost temperature
1. When reading the temperature, make sure the thermometer goes deep into the pile, leave the thermometer for a while to allow the temperature to stabilize before taking the reading, then move it to a new location (including several locations at different depths from the top edge ).
2. The temperature of the pile depends mainly on the moisture content and chemical composition of the raw material components.
3. There is a certain gradient in the change of fermentation temperature. For the system with bottom ventilation, the highest temperature is about 2/3 of the bottom or higher.

Can Fertilizer Fermentation Tank Finish Composting in 8 Hours

The organic fertilizer fermentation tank is very popular in the organic fertilizer market due to its small footprint, fast heating, high fermentation efficiency, good sealing and no secondary pollution to the surrounding environment. In order to attract customers, some businesses claim that the organic fertilizer fermentation tank they produce can quickly complete fermentation in only 8 hours. Is this credible?

Fermentation principle of organic fertilizer

Fermentation of organic fertilizer is to mix a certain proportion of compost base material and filler, and under appropriate temperature, humidity and ventilation conditions, the organic matter is degraded by microorganisms to form stable humus and minerals and other beneficial substances that are easily absorbed by soil and plants . This is also called aerobic fermentation.

The entire fermentation process is the process of death, replacement and morphological transformation of various organisms and microorganisms in the material. Whether from the perspective of biology, thermodynamics or material transformation, these reactions cannot be completed in a few hours.

Using the In- vessel fermentation tank, the temperature rises quickly, and the fermentation process is advanced. However, the claim that some manufacturers advertise that the fermentation can be completed in only 8 hours is completely wrong. 8 hours only kills the parasites and worms in the organic fertilizer raw materials. Pathogenic microorganisms and harmful bacteria have realized the harmless treatment of raw materials, and the fermentation is far from complete. Click here to know more about composting of  fertilizer fermentation tank.

Under normal circumstances, it takes 20 days to complete the fermentation of organic fertilizers using organic fertilizer fermenters, and in order to continue to decompose difficult-to-degrade substances and make the nutrients of organic fertilizers more stable, after unloading from the fermenter, try to decompose as much as possible. Aging for a while.

Advantages of organic fertilizer fermenter

Fermentation tanks are very popular in the market, what are the advantages?

  • Small space occupation: Compared with the traditional fermentation method of stacking materials on the ground, the space occupation of fermentation pot is very small.
  • Environmental protection: Equipped with odor treatment equipment, the odor generated during the in- vesssel fermentation process is collected and processed in a centralized manner, which can realize the discharge of gas up to the standard, and will not cause secondary pollution to the surrounding environment.
  • High fermentation efficiency: The fermentation cycle takes less than days, which saves half the time compared to traditional fermentation methods.
  • Not affected by ambient temperature: Since the fermentation of organic fertilizer is related to temperature, the ambient temperature is lower than 10 degrees, it is difficult for the raw materials to heat up, the fermentation cycle becomes longer, and the fermentation will be affected. However, the main body of the fermentation tank adopts a thermal insulation design and is equipped with a heating system. The equipment can also operate normally in a low temperature environment, which solves the impact of ambient temperature on the fermentation process.
