Organic Fertilizer Compost Fermentation Common Problems —— Pile Body Temperature is too High

In the process of composting organic fertilizer, the causes of excessive temperature of the pile are mainly oversized pile, low moisture content, insufficient aeration, etc.

I. Pile Body is too Large
1. Reason Analysis
When the height of the pile exceeds 2m or the width exceeds 6m, it is easy to cause the heat in the pile cannot be dissipated in time, and the temperature of some piles even exceeds 75 degrees. This phenomenon may appear in the primary fermentation or post-ripening/storage stage. If the pile temperature in post-ripening or storage is too high, it may be due to the premature end of primary fermentation.
2. Solution Measures
Reduce the height or width of the pile and delay the primary fermentation time appropriately. If the site is limited, a blower can be placed in the fermentation tank to increase the contact of the pile with air.

II. The Moisture Content is Low
1. Cause Analysis
When the moisture content in the compost is medium to low (sometimes the pile looks moist, but in fact the moisture content is not enough), evaporation and heat dissipation is insufficient, and the pile cooling is restricted, which easily leads to high pile temperature. Some areas appear high temperature decomposition or even spontaneous combustion, the interior of the pile looks or smells like burnt.
2. Solution Measures
Add water to the high temperature, burnt and smoldering parts, crack the pile to maintain the right moisture content, keep turning the pile and aeration to control the temperature.

III. Insufficient Aeration
1. Cause Analysis
On the one hand, insufficient aeration may lead to slow heating of the pile; on the other hand, it may also lead to poor heat dissipation of the pile. Although the average moisture content of the pile is appropriate, but the local may be too high, resulting in poor gas flow, heat dissipation channel is not sufficient.
2. Solution Measures
Turn the pile or increase the rate of aeration.
