Organic Fertilizer Fermentation Process, Hands-On Strip Composting

Strip composting without the construction of a fermenter, low investment costs, simple operation, is a more common way of composting systems, this article on the operation of the strip composting steps to explain in detail.

Top pile
The mixed raw materials are piled on the fermentation field into a nearly trapezoidal strip chop with a width of 1.8-3 meters at the bottom, 0.8-1 meters at the top and 0.6-1 meters at the height, with an interval of 0.5 meters between the strip chops. The specific width and height of the strips are determined by the tilting equipment.

Composting
Insert automatic temperature recorders in the upper, middle and lower parts of the pile, respectively, 3-6 in each pile.

Use about 2cm thin rod on the pile body from top to bottom oblique insertion of a number of small breathable holes, all the way to the bottom of the pile; 10-20 holes inserted per meter of pile body.

When the initial yard pile temperature is lower than 15 degrees, you can cover the pile with a layer of plastic film, when the film thin with uniform water droplets appear, uncover the plastic sheet.

Pile Turning
Each day of the upper pile of fermented raw materials as a batch, and insert the compost fermentation signboard. The temperature of raw materials on the pile will rise to about 60 degrees within 24-48h, and after keeping it for 24h, start turning the pile (but when the temperature exceeds 70 degrees, the pile must be turned immediately), make sure to turn the pile evenly and thoroughly, and turn the low-level materials into the upper part of the pile as much as possible in order to fully decompose.

End of Fermentation
Fermentation composting process consists of four stages: low temperature, medium temperature, high temperature and cooling. Temperature from low to high and then gradually back down to the room temperature difference of less than 10 degrees, you can end the main fermentation.

The materials finished by high temperature rotting will be post-rotted for 10-15d, and the moisture will be reduced to below 35% after the fermentation is completed.

Record
During the whole fermentation process, in addition to the turning operation, the fermentation temperature and water content of the material should be measured and recorded daily to make production records.
