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.

Things You Need To Focus On About Windrow Composting

The windrow compost turning machine can be said to be the core equipment in the current organic fertilizer production process. It can control the fermentation temperature and the moisture in the stack during the windrow fermentation process. At present, the more advanced compost machines on the market can achieve no dead angle turning, and can complete the composting operation of all materials in one workflow.

So is there anything that needs to be paid attention to in the process of using the windrow compost turning machine to ferment organic fertilizer?

1. Pay attention to the temperature, oxygen content and moisture content in the fermentation raw materials. Temperature, oxygen and moisture are directly related to the windrow fermentation cycle of organic fertilizers and the quality of the finished product. Therefore, special attention should be paid to these three aspects when using a turning machine to ferment organic fertilizers. The purpose of the turning operation is to control the temperature, increase the oxygen content in the material, and reduce the moisture content, but it is also necessary to pay attention not to turn too frequently, so as not to affect the temperature increase in the stack.

2. The stacking should not be too high. When using a turner for fermentation, the width of the windrows can be determined according to the output. The height of the compost should be between 0.8 and 1.5 meters. If the height of the compost is too high, it will affect the air permeability of the raw materials, resulting in oxygen content in the stack. Insufficient amount affects fermentation.

3. Pay attention to the freshness of the raw materials. If the raw materials are stored for too long, anaerobic conditions may be formed. Under the anaerobic state, the organic matter content in the raw materials will gradually decrease, which will affect the quality of the finished products. If such raw materials are used to ferment organic fertilizer, attention should be paid to adding fresh raw materials for adjustment.

4. Pay attention to the turning  time of windrow composting. When using a turning and throwing machine for fermentation, it usually takes 10-15 days for the initial fermentation to decompose. The turning and throwing time can be determined according to the temperature in the stack. It is tossed a second time, followed by a second aging and fermentation, usually 3-7 days.

5. Pay attention to the nature of the fermentation raw materials. There are many raw materials that can be used to ferment organic fertilizers, such as grass and wood fragments, crop straw, livestock and poultry manure, etc., but the carbon and nitrogen ratios in different raw materials are different, and the fermentation cycle is also different. To ensure the quality of the finished product after fermentation, targeted adjustments should be made before fermentation, which can be applied after mixing different raw materials evenly.
