Specific methods and steps of chicken manure organic fertilizer fermentation

How is chicken manure fermented? Specific methods and steps for fermenting chicken manure organic fertilizer:

Step 1: Mix the starter. Fresh chicken manure and other livestock and poultry manure mixture is about 5 tons plus 1 kg of Rw organic fertilizer starter. For every kg of Rw organic fertilizer starter, add an average of 10 kg of rice bran or corn and bran, stir it evenly, and sprinkle it into the prepared materials. Medium (referring to the chicken manure with the dry humidity adjusted in step three), the effect is good.

Step 2: Adjust the carbon to nitrogen ratio. The carbon to nitrogen ratio of fermented fertilizers should be maintained at 25~30:1, and the pH should be adjusted to 6~8 (ph). Due to the high carbon to nitrogen ratio of chicken manure, some straw, straw, mushroom residue, etc. should be added during fermentation. Ferment together.

Step 3: Adjust the moisture of chicken manure. In the process of fermenting organic fertilizers, whether the moisture content is appropriate is very important. It should not be too high or too low. It should be kept within 55%. Judgment method: hold a handful of the material tightly, see the watermark on your fingers, but not drip, and it can fall on the ground. It is advisable to disperse it (if the moisture is too high, add dry straw powder, wheat bran, bran, etc. to neutralize the moisture).

Step 4: Build a pile of chicken manure. When making a fermentation pile, it should not be too small or too short. Too small will affect the fermentation. Generally, the height is about 1.5 meters, the width is about 2 meters, and the length is more than 2 to 4 meters. The fermentation effect is better.

The upper layer is covered with semi-wet straw (especially for heat preservation during composting in winter). If it rains, you can simply cover it with plastic film, but it does not need to be sealed. It cannot be sealed and should be stacked as loosely as possible). The plastic film can be opened once a day to facilitate aeration and aerobic fermentation. In order to avoid rain, a rain shed can also be set above the material to prevent rain from getting wet. .

When building a pile of chicken manure materials, it is advisable to add organic materials such as straw powder, mushroom residue, peanut hull powder, or rice husk, sawdust, etc. to the materials in order to adjust the aeration. If rice husks and sawdust are added, the fermentation time should be prolonged because of the higher cellulose and lignin.
