Chicken manure is one of the most nutrient-rich livestock and poultry manures—dry chicken manure can contain up to 50% organic matter, 3.2% nitrogen, 3.1% phosphorus (P₂O₅), and 2.4% potassium (K₂O). However, uncomposted chicken manure contains a large number of pathogens, insect eggs, and parasites, and direct application to the soil can cause root and seedling burn. Therefore, chicken manure...

Standardized fertilizer production lines typically employ a straight-line process: raw materials → weighing → mixing → granulation → drying → cooling → screening → packaging. However, actual site conditions vary greatly—limited by factory columns, height restrictions, irregular terrain, or environmental zoning requirements, a straight-line layout cannot be directly implemented. In such...

In major palm oil producing regions such as Malaysia and Indonesia, a large amount of empty palm fruit bunches (EFB) are generated annually. These fibrous wastes have a high moisture content (up to 70%) and contain hard lignin, resulting in extremely slow natural decomposition. Converting them into organic fertilizer not only alleviates environmental pressures but also creates export value. This...

Besides nutrient content, appearance is the first quality signal customers perceive in commercial organic fertilizer. Color, moisture content, and particle uniformity are three sensory and basic physical indicators that quickly reflect the degree of fermentation and decomposition, processing technology, and storage stability. This article provides a set of operational evaluation standards from a...

NPK 18-18-18 is a high-concentration balanced compound fertilizer with a total nutrient content of 54%, with equal proportions of nitrogen, phosphorus, and potassium, suitable as a base fertilizer for various crops. The key to producing this formula lies in precise ingredient proportioning, efficient mixing, steam drum granulation, and strict drying, cooling, and coating processes. This article...

NPK 15-5-20 is a high-potassium compound fertilizer with a total nutrient content of 40%, of which potassium content reaches 20%, significantly higher than nitrogen and phosphorus. This formula is suitable for potatoes, tobacco, sugar beets, fruit trees, and root and tuber crops, and has a significant effect on improving fruit quality and enhancing stress resistance. When producing the high...

What is high-tower granulation technology? High-tower granulation is an advanced compound fertilizer production process. Its core principle is melt spray self-forming. Raw materials such as urea, monoammonium phosphate, and potassium chloride are heated to 110-130℃ in a melting tank to form a highly fluid molten slurry. This slurry is then sprayed downwards from the top of a granulation tower...

My country produces a large amount of crop straw annually. Directly returning it to the field results in slow decomposition and susceptibility to pathogens. Converting it into commercial organic fertilizer is a highly efficient way to utilize its resources. Achieving this conversion hinges on three key technologies: straw softening treatment, application of rapid fermentation agents, and...

Organic fertilizer granules are highly susceptible to cracking, chipping, and even pulverization during the drying and cooling processes due to mechanical collisions and thermal stress. The key to protecting granule integrity lies in rationally setting the drum rotation speed, in conjunction with the air temperature curve and the internal lifting plate structure. This article provides an operable...

NPK 25-10-10 is a high-nitrogen compound fertilizer with a total nutrient content of 45%, significantly higher than phosphorus and potassium. This formula is suitable for use as a base fertilizer or top dressing for gramineous field crops such as corn, wheat, and rice, as well as leafy vegetables. High nitrogen promotes rapid stem and leaf growth, while appropriate amounts of phosphorus and...
