Product Information

NPK Compound Fertilizer is a uniform mixture containing the three primary essential nutrients for plant growth: Nitrogen (N), Phosphorus (P), and Potassium (K). The product is typically granular with a specific nutrient ratio (e.g., 15-15-15). It supplies multiple nutrients simultaneously, meeting the basic requirements of crops throughout their growth cycle, effectively improving fertilizer use efficiency, crop yield, and quality. It is the most widely used fertilizer type in modern agriculture.

Product Nature


  1. Physical Properties:
    · Appearance: Colored (grey, brown, white, etc.) or natural-colored granules
    · Particle Size: Typically regular granules with 2-4 mm diameter
    · Bulk Density: Approx. 1.0 - 1.3 g/cm³
    · Solubility: Available nutrients are readily soluble in water, providing fast availability
    · Hygroscopicity: Hygroscopic, may cake upon moisture absorption

  2. Chemical Properties:
    · Nitrogen (N): Primarily exists as ammonium nitrogen (NH₄⁺) and nitrate nitrogen (NO₃⁻), promoting protein synthesis and stem/leaf growth.
    · Phosphorus (P): Exists as water-soluble monoammonium/diammonium phosphate, promoting root development, flowering, fruiting, and energy transfer.
    · Potassium (K): Exists as water-soluble potassium salts (e.g., KCl, K₂SO₄), enhancing stress resistance, photosynthesis, and fruit quality.
    · The components are chemically stable and compatible with each other.

Product Usage

  1. Field Crops: Used as base or top-dressing fertilizer for rice, wheat, corn, cotton, etc., to provide comprehensive and balanced nutrition.

  2. Cash Crops: Suitable for fruits (e.g., citrus, apples), vegetables, tea, sugarcane, etc., to improve yield and commercial value.

  3. Horticulture & Turf: Used in flower production, seedling cultivation, and the maintenance of golf courses and urban lawns.

  4. Other Applications: Different NPK ratios (e.g., high-nitrogen, high-potassium) can be selected based on specific soil and crop needs for precision fertilization.

Safety Matters


  1. Health Hazards:
    · Dust may cause mild irritation to eyes, skin, and respiratory tract. Prolonged dust inhalation may affect the respiratory system.
    · Ingestion of large amounts may cause gastrointestinal discomfort.
    · Nitrate ions may be converted to nitrites under certain conditions, posing potential health risks.

  2. Handling Protection:
    · Wear appropriate dust masks, gloves, and eye protection during handling.
    · Wash hands and exposed skin thoroughly after handling.
    · Avoid dusty operations in confined spaces or windy conditions.

  3. Storage & Transportation:
    · Store in a cool, dry, well-ventilated warehouse. Protect from sunlight, rain, and moisture.
    · Store separately from food, beverages, feedstuffs, strong acids, and strong alkalis.
    · Stacking height should not be excessive to prevent crushing and collapse.
    · Protect against moisture to prevent caking.

  4. Environmental Safety:
    · Prevent dust dispersion and product spillage to avoid local eutrophication pollution of water bodies and soil.
    · Apply according to recommended dosage and methods. Over-application can lead to nutrient runoff and environmental pollution.
