With the continuous advancement of green agriculture and farmland improvement policies, the market demand for organic fertilizer is steadily increasing, and the penetration rate of domestic organic fertilizer production lines is constantly improving. However, most small and medium-sized production enterprises still suffer from outdated technology, backward equipment, extensive management, and weak environmental protection, which restricts the upgrading of organic fertilizer product quality and the standardized development of the industry, becoming a major bottleneck in the resource utilization of agricultural waste.
Immature production technology and low production efficiency are the most common problems in production lines. Traditional production lines mostly adopt extensive fermentation modes, with high-temperature aerobic fermentation cycles lasting more than 60 days, which is time-consuming and inefficient. At the same time, most enterprises lack precise raw material ratio processes, and the mixing ratio of raw materials such as livestock and poultry manure and straw is arbitrary, easily leading to uneven fermentation and insufficient decomposition. This not only causes nutrient loss in organic fertilizer but also results in products containing pathogens and insect eggs, failing to meet harmless production standards and seriously affecting fertilization effects.
Outdated equipment and insufficient level of automation are prominent shortcomings in the industry. Currently, many small and medium-sized organic fertilizer production lines still use traditional, outdated equipment. This results in low crushing and screening precision, inconsistent granulation pass rates, and a high level of impurities in the finished product. The overall automation level of these production lines is low, relying heavily on manual batching, turning, and packaging. This not only leads to high labor costs but also significant measurement errors and inconsistent production standards, making it difficult to achieve large-scale, standardized mass production and causing significant batch-to-batch quality variations.
Weak environmental management and inadequate pollution treatment are problems that urgently need to be addressed. The fermentation process in organic fertilizer production generates ammonia and odorous gases, and the process is accompanied by pollutants such as dust and washing wastewater. Most enterprises have rudimentary environmental protection facilities, with incomplete deodorization and dust removal systems, resulting in uncontrolled emissions of waste gas. This not only pollutes the factory area and surrounding environment but also fails to meet environmental compliance standards, posing risks of rectification or shutdown.
Furthermore, the severe homogenization of organic fertilizer production lines and the lack of refined management lead to products with limited functionality and low added value. Most production lines can only produce ordinary organic fertilizer, unable to adapt to the needs of different soils and crops. The industry suffers from overcapacity in low-end products and insufficient supply of high-end functional organic fertilizers, severely restricting the high-quality development of the organic fertilizer industry.
