Common quality issues in organic fertilizer production lines mainly include the following:

1. Substandard nutrient content: The total nutrient content of some organic fertilizer products falls below national standards.

2. Excessive heavy metal content: Some organic fertilizer products contain excessive heavy metals. Heavy metal content varies significantly among different raw materials, with high levels generally found in cow dung, chicken manure, and sugar residue.

3. Inadequate fermentation: Improper temperature control during the fermentation process prolongs fermentation time, impacting production efficiency. Some companies neglect high-temperature fermentation, resulting in organic fertilizer products failing to meet harmless standards.

4. Poor pellet quality: Pellets break easily during transportation, impacting application effectiveness. Uneven pellet size during granulation affects fertilization effectiveness.

5. Non-standard production processes: Some companies use rudimentary organic fertilizer equipment and outdated processes, making product quality unreliable. Most companies are small and medium-sized enterprises with limited production scales, making it difficult to establish a strong brand.

Solutions:

Optimize production processes: Use advanced fermentation equipment and granulation technology to improve production efficiency and product quality. Strengthen quality control: Establish a strict quality inspection system to ensure product compliance with national standards.

Standardize the production process: Strengthen standardized management of the production process to ensure a thorough fermentation process.

Improve equipment: Update production equipment to enhance automation and intelligence.

Through these measures, common quality issues in organic fertilizer production lines can be effectively addressed, improving product quality and market competitiveness.
