The core raw materials for bio-organic fertilizer production lines are various organic wastes. Their efficient conversion into high-quality organic fertilizer hinges on the core characteristics of the raw materials themselves.
1.Pure Organic Properties and No Pollutants
Processable raw materials must be composed primarily of natural organic matter, such as poultry and livestock manure, straw, mushroom residue, distiller’s grains, and garden leaves, free from excessive heavy metals and toxic chemical residues. Pure organic properties ensure that the resulting organic fertilizer is free from secondary pollution, while providing a pure nutrient substrate for beneficial microorganisms, preventing harmful substances from affecting microbial activity and the final fertilizer’s effectiveness.
2.High Decomposability and Suitable C/N Ratio
Raw materials must contain sufficient amounts of organic matter that can be decomposed by microorganisms, such as cellulose, hemicellulose, and protein. These substances can be decomposed into humus during fermentation, becoming nutrients that crops can absorb. Simultaneously, the raw materials must have an adjustable C/N ratio, adjusted to a suitable fermentation ratio of 25-30:1 to ensure efficient aerobic fermentation.
3.Abundant Nutrient Potential and Stable Source
The raw materials for processing must naturally contain basic nutrients such as nitrogen, phosphorus, and potassium, as well as micronutrients such as calcium, magnesium, and sulfur. After fermentation, these nutrients can be converted into long-lasting, slow-release organic nutrients to meet the needs of crop growth. Simultaneously, the raw materials must have large-scale supply capabilities, such as livestock manure from the poultry industry and straw waste from agricultural production. These sources are stable and concentrated, suitable for the continuous production requirements of bio-organic fertilizer production lines.
These core characteristics make organic waste a high-quality raw material for bio-organic fertilizer production, solving the environmental problem of waste disposal and, through scientific transformation in the production line, allowing “waste” to realize its fertilizer value.
