Livestock manure is rich in nutrients. Taking pig manure as an example, the pig manure organic fertilizer production process can recycle these agricultural wastes containing nutrients very well. Since livestock and poultry manure contains a large amount of organic matter and rich nitrogen, phosphorus, potassium and other nutrients, it is a valuable resource for sustainable agricultural development. Farmers have used it as a source of soil fertility for thousands of years. In terms of the production method of organic fertilizer, farmers used to produce organic fertilizer through composting. Nowadays, with the development of intensive farms, we have explored the fertilizer technology of livestock and poultry manure, and realized the production of general organic fertilizer, npk production line and bio organic fertilizer production through organic fertilizer production equipment.
With the development of the times, composting is still one of the effective ways to deal with various organic wastes, and it is a biological fermentation method that integrates treatment and resource recovery. Mix the collected feces with organic fertilizer starter, adjust the carbon-to-nitrogen ratio in the feces, and control the appropriate moisture, temperature and pH value for alcoholization. The advantage of this method of manure treatment is that the final product has less odor, is dry, easy to pack and use, and is beneficial to the growth and development of crops. However, there will also be some problems, such as the loss of ammonia gas during the treatment process, the odor cannot be completely controlled, the composting needs a large area, and the treatment time is long, etc., which will indirectly lead to an increase in costs. Although the self-propelled stacker used for stacking is flexible, the choice of tank fermentation system will well eliminate the above-mentioned negative factors. Moreover, the trough fermentation system has a variety of stacker equipment such as trough stacker or chain plate stacker to choose from, which is more purposeful in output configuration.
