Pig manure, as a high-quality organic fertilizer source, contains abundant nutrients such as nitrogen, phosphorus, and potassium. Through proper fermentation treatment, it can be converted into efficient agricultural fertilizers. The following are the basic steps for fermenting and processing pig manure into fertilizer using organic fertilizer turners, especially self-propelled or double helix turners:
Initial preparation
Collection and preliminary processing: Firstly, collect fresh pig manure and remove impurities such as plastic bags, sawdust, and other non organic substances.
Adjusting moisture content: The initial moisture content of pig manure is relatively high and usually needs to be adjusted to around 50% -60% to facilitate microbial activity. It can be adjusted by adding straw powder, sawdust, or other dry materials.
Fermentation process
Stacking: Mix the processed pig manure with other auxiliary materials (such as rice husks, corn stalks, and other carbon sources) in a certain proportion to construct a fermentation pile. The size of the pile should be determined based on the model and processing capacity of the flipping machine.
Adding bacterial strains: To accelerate the fermentation process, specialized fermentation agents such as EM bacteria, yeast, etc. can be spread on the pig manure pile to stimulate microbial activity.
Start turning: Use an organic fertilizer turning machine to start the turning operation. The purpose of turning is to increase oxygen supply, promote microbial activity, and accelerate decomposition.
Temperature management: As fermentation progresses, the reactor will self heat up, and temperature changes should be closely monitored. Ideally, it should be maintained between 50 ° C-65 ° C. During this period, the reactor should be flipped regularly to maintain temperature stability and avoid local overheating causing nutrient loss.
Observation and adjustment: During the fermentation process, continuously observe the condition of the heap. If necessary, adjust the moisture and ventilation status by spraying water or adding dry materials.
Finished product processing
Maturity judgment: When the heap stops heating, the color changes to dark brown, the texture is soft, and there is no obvious odor, it indicates that fermentation is basically completed.
Screening and packaging: Use screening equipment to remove large chunks that have not been decomposed, and then crush, mix, package, and store mature fertilizers for easy transportation and sales.
Through the scientific application of organic fertilizer composting machines, pig manure can not only be effectively treated, but also transformed into valuable agricultural resources, which not only solves the environmental problems of animal husbandry, but also provides green fertilizers for agricultural production, achieving ecological cycling. Reasonable control of moisture, temperature, and ventilation is crucial throughout the entire fermentation process to ensure smooth fermentation and the production of high-quality organic fertilizers.
