How to Choose the Right Chicken Manure Fermentation Agent for Quick Organic Fertilizer Production?
Traditionally, chicken manure was left to ferment naturally for 5–6 months, which not only caused unpleasant odors and environmental pollution but also led to significant nutrient loss. Using a fermentation agent can speed up the process and make it more efficient. However, different types of fermentation agents vary greatly in performance, affecting factors like fermentation time, dosage, cost, operation complexity, labor intensity, and the final quality and smell of the compost.
First, using a microbial straw fermentation agent for chicken manure:
When using a microbial straw fermentation agent, the process typically takes about 20 days. The resulting compost becomes odorless, harmless, soft, and has a yellow-brown color with pale white hyphae. The organic matter content reaches around 45%.
The process involves spreading the chicken manure on a tiled ground surface, adding water at 35% of the manure's weight, and mixing in 2 kg of straw fermentation agent per ton of manure. The agent should be diluted with rice bran or wheat bran, along with 15 kg of superphosphate. Adding grass powder or peat (100–150 kg) helps improve texture. The pile is then turned twice, formed into a rectangular heap about 1 meter high and 2 meters wide, and ventilated by poking holes on top. A plastic sheet covers the pile, sealed tightly to the ground with heavy objects placed every meter to prevent wind damage. In summer and autumn, the cover should be removed once a day for 1–2 hours. On sunny days, the cover can be taken off in the morning and replaced in the evening. After 4–6 days, the internal temperature rises to 60–70°C. For fresh manure, start by laying down a layer of straw powder, rice bran, grass powder, peanut shell powder, or peat moss, then spread the wet chicken manure on top. Sprinkle 0.1% urea and about 20 kg of superphosphate per ton, and mix 2 kg of straw starter with bran or rice bran. During fermentation, turn the pile twice and form a stack 1.5–2 meters wide and 1 meter high, making ventilation holes with a stick. Cover with a plastic sheet to retain heat and moisture. Proper ventilation is essential. After 10 days, the pile can be turned again. The entire process takes about 20 days, resulting in high-quality fertilizer that eliminates harmful pests.
Second, using a Kinpo-type fermentation agent:
For chicken manure fermentation using a Goldbaby-type agent, add 1 kg of the starter to 1 ton of organic material (approximately 2.5 tons of fresh material), and mix it with 5 kg of rice bran (or alternative like wheat bran or corn meal) per kilogram of the starter. This mixture is evenly distributed into the pile and fermented. It’s better to use fresh rice bran rather than old ones. During the process, ensure proper aeration and turning. Keep the temperature around 70°C—too high may damage nutrients. Maintain the moisture level between 60–65%. If too wet, add materials like straw, sawdust, mushroom residue, or dry soil. If too dry, add water. The right moisture level is when you can squeeze a handful of material and see a watermark without dripping, and it falls apart easily. The whole process usually completes within 5–7 days.
As shown, using the Golden Baby Fermentation Agent makes the treatment of chicken manure faster, simpler, and more efficient, making it an excellent tool for chicken farms, pig farms, fertilizer factories, and small-scale homesteads.
