NPK compound fertilizer, a widely used type of fertilizer in agricultural production, features a scientifically formulated combination of three core nutrients: nitrogen (N), phosphorus (P), and potassium (K). It provides comprehensive and balanced nutrient support for crop growth and is a key option for efficient fertilization in modern agriculture.
N refers to nitrogen fertilizer, which improves soil fertility, promotes plant growth, enhances photosynthesis, and increases chlorophyll content.
P refers to phosphorus fertilizer, which enhances plant resilience, promotes bud formation and flowering, strengthens stems and branches, and accelerates fruit ripening.
K refers to potassium fertilizer, which strengthens plant stems, enhances disease, insect resistance, and drought resistance, and improves fruit quality.
NPK compound fertilizers offer exceptional flexibility in their formulations. Manufacturers can customize their formulas based on soil fertility, climate conditions, and crop types in different regions.
Common Granulation Methods
NPK compound fertilizers place stringent demands on the compatibility of granulation equipment due to the raw material characteristics (nitrogen easily absorbs moisture, phosphorus easily agglomerates) and the finished product requirements (uniform granules and satisfactory strength). Currently, the mainstream granulation equipment in the industry includes disc granulators, rotary drum granulators, and extrusion granulators.
Production Process
Raw material collection and pretreatment → Crushing and screening → Ingredient mixing → Granulation → Drying and cooling → Screening and packaging
Features of NPK Fertilizer
Nutrient synergy and high efficiency: A scientifically formulated combination of nitrogen, phosphorus, and potassium avoids imbalances in individual elements, synergistically improving crop absorption efficiency and increasing yields by 10%-15% compared to a single fertilizer mix.
Convenient and labor-saving application: Granular fertilizers integrate multiple nutrients, meeting multi-stage needs with a single application, reducing fertilization frequency by 50% and increasing nutrient utilization to over 80%.
Flexible and adaptable formulas: Customizable according to crop type, soil characteristics, and growing period, covering fields, fruits, and vegetables, and addressing specific planting needs.
Stable Storage and Transportation Performance: Pellets boast a strength exceeding 8N, are resistant to breakage, and have low moisture absorption. They maintain no caking after 6 months of storage at 80% humidity, and their transportation loss rate is less than 3%.
