Livestock manure is an ideal high-efficiency bio-organic fertilizer in the agricultural production process. Appropriate application of livestock and poultry manure can improve soil, fertilize soil and prevent soil degradation. However, direct application will cause environmental pollution and decline in the quality of agricultural products.
The livestock and poultry manure is processed into organic fertilizer through organic fertilizer equipment. The production of organic fertilizer mainly includes two processes: pre-fermentation and post-granulation. Common organic fertilizer granulators include: npk fertilizer granulator, drum granulator , disc granulator machine, new organic fertilizer granulator, new two-in-one organic fertilizer granulator, flat die granulator, ring die granulator, each granulator has its own production characteristics, fertilizer granulator machine price vary. At the same time, fermentation is the most important thing. What are the hazards of unfermented livestock and poultry manure?

Hazards of unfermented livestock and poultry manure:
Infection by pests and diseases: Feces contain a large number of microorganisms harmful to human health, such as Escherichia coli and nematodes. Direct fertilization will spread pests and diseases, making plants prone to disease, polluting the environment, and adversely affecting human health.
Burning seedlings: Once the fermentation conditions are reached, the unfermented manure in the soil contains active microorganisms, and the heat generated during the fermentation process will seriously affect plant growth or cause seedling burning.
Toxic gas hazard: Feces will produce sulfur dioxide and ammonia gas, which are toxic gases to crops and the atmospheric environment. Oxygen-depleted soil: Organic matter consumes a lot of oxygen in the soil during the decomposition process.
Slow fertilizer effect: The nutrients in unfermented manure are slow-release fertilizers and cannot be directly absorbed and utilized by plants. Environmental pollution: After wind and rain, the fertilizer effect of manure is washed away, polluting rivers and soil.
Inconvenient transportation: Untreated livestock manure is bulky and inefficient, which is inconvenient for transportation and practical application.
