Using chicken manure as an example to produce humic acid organic fertilizer
1. Collection and processing of chicken manure: Firstly, collect fresh chicken manure and remove impurities and harmful substances through treatment. During the processing, it may be necessary to dilute with water or soak in water and chop it into small pieces for the subsequent fermentation process.
2. Adjusting the water content and carbon nitrogen ratio: The water content and carbon
nitrogen ratio of chicken manure are important factors affecting the fermentation effect. As needed, an appropriate amount of dry matter (such as straw, rice husk, etc.) can be added to adjust the water content and carbon nitrogen ratio to achieve suitable fermentation conditions.
3. Adding fermentation agents: Add an appropriate amount of fermentation agents, such as composting
bacteria, lactic acid bacteria, etc., to the adjusted chicken manure. These microbial agents can accelerate the maturation process of chicken manure and improve the efficiency of humic acid formation.
4. Stacking fermentation: Stack chicken manure with added microbial agents into piles and cover them with plastic cloth to maintain appropriate temperature and humidity. During the fermentation process, it is necessary to regularly flip and stir the chicken manure pile to ensure uniformity and ventilation of the fermentation.
5. Maturity and aging: After a period of fermentation, chicken manure will gradually mature and produce humic
acid. During the process of maturation, aging treatment is also required, which means that the decomposed chicken manure will continue to be stacked for a period of time to further stabilize and increase the content of humic acid.
6. Granulation and drying: After aging is completed, the chicken manure is crushed and screened, and other nutrients are added for granulation,drying, and screening to obtain a solid humic acid fertilizer with uniform particles and easy application.
7. Packaging and storage: The screened solid humic acid fertilizer can be packaged with plastic bags, paper bags, and other packaging materials.Packaged fertilizers should be stored in a cool and dry place, avoiding direct sunlight and moisture.
