How to adjust the PH value of compost during organic fertilizer fermentation?

Organic fertilizer raw materials need to be fermented when processed by organic fertilizer granulator, and fermentation bacteria play an important role in this case. Fermentation bacteria are suitable for neutral or alkaline environment, which is beneficial to the reproduction, decomposition and survival of fermentation bacteria. Improper pH will affect the reproduction, decomposition and survival of fermentation bacteria. In order to exert the fermentation effect, it is necessary to adjust the pH value to achieve the effect.

When the pH value is high, it can generally be adjusted by adding an appropriate amount of weathered coal powder, lignite powder, peat powder and other substances. These substances are called "low-grade coal", and their pH values are all below 4. Adding them to organic fertilizers can effectively reduce the pH value of organic fertilizers.

If the PH value is too low, it is mainly affected by excessive moisture or too fine materials. At this time, the oxygen content in the compost is low, and the fermentation of organic waste such as manure can easily become anaerobic. When it becomes anaerobic, the activity of fermentation bacteria in the fertilizer will be seriously affected. When it ceases activity and goes dormant or dies, it accumulates organic acids. The accumulation of organic acids can lower the pH to 4.5. At this time, we can realize the importance of compost turning machine. The compost turner can provide oxygen by turning the compost, the material is more breathable than before, and the oxygen content is sufficient, so that the pH environment of organic waste such as manure can be restored to normal.
