BB fertilizer (bulk blending fertilizer) comes in several types, so the raw materials vary. The main ones include: 1. Elemental Fertilizers Nitrogen: urea, ammonium nitrate, ammonium sulfate. Urea is most common — high nitrogen, moderate price, water-soluble. Phosphorus: MAP, DAP, superphosphate. MAP and DAP are widely used for high phosphorus content and good solubility. Potassium: potassium chloride, potassium sulfate. KCl is the main source (high content, low price); K₂SO₄ suits chlorine-sensitive crops. 2. Compound Fertilizers Potassium dihydrogen phosphate, potassium nitrate, etc. They provide multiple nutrients and simplify formula design. 3. Trace Element Particles Borax, zinc sulfate, manganese sulfate, copper sulfate — supplement crop micronutrients. 4. Functional Additives Anti-caking agent: prevents clumping during storage and transport. Slow-release coating: e.g. biodegradable coatings, controls nutrient release. Enhancers: e.g. humic acid, improves fertilizer utilization and crop stress resistance. 5. Other Auxiliary Materials Filler: crushed limestone, adjusts particle size and specific gravity. Coloring agent: distinguishes different formulas or brands. Key Requirements Similar particle size (usually 2–4 mm) High particle strength Dry, no clumping Why BB Fertilizer Raw Materials Matter Flexible formula for different crops, soil, and climate Comprehensive nutrients Simple process: mechanical mixing, no chemical reactions, high efficiency, low cost
