Scope

Main Technical Content: 4.1 Requirements 4.1.1 Appearance: Powdery or granular solid products, free from mechanical impurities. 4.1.2 Product Type: According to the type of nutritional elements added (phosphorus and potassium), trace element mineral fertilizers are divided into phosphorus-based and potassium-based types. 4.1.2.1 Phosphorus-based trace element mineral fertilizers shall comply with the requirements in Table 1 and meet the values indicated on the packaging container. Table 1: Requirements for Phosphorus-Based Trace Element Mineral Fertilizers Parameter Value Macronutrients (calculated as elemental compounds) a ≥25% Micronutrients (calculated as elemental compounds) b ≥0.2% Available phosphorus (calculated as P2O5) c ≥15.0% Water content (H2O) d ≤8.0% Particle size (1.00mm–4.75mm or 3.35mm–5.60mm) e ≥90% (Note: For phosphorus-based fertilizers, the macronutrient content refers to the sum of calcium, magnesium, and sulfur, with a minimum macronutrient content of 2%. For potassium-based fertilizers, the micronutrient content refers to copper, iron, manganese, zinc, boron, and molybdenum, with a minimum micronutrient content of 0.02% (except for molybdenum, which should not exceed 0.5%).) 4.2 Special Requirements 4.2.1 Phosphorus-Based Trace Element Mineral Fertilizers 4.2.1.1 Phosphorus-Based Trace Element Mineral Fertilizers shall comply with the requirements in Table 2 and meet the values indicated on the packaging container. Table 2: Requirements for Potassium-Based Trace Element Mineral Fertilizers Parameter Value Macronutrients (calculated as elemental compounds) a ≥20.0% Micronutrients (calculated as elemental compounds) b ≥0.2% Soluble silicon (SiO2) c ≥20.0% Potassium (calculated as K2O5) d ≥5.0% Water content (H2O) e ≤2.0% Particle size (1.00mm–4.75mm or 3.35mm–5.60mm) f ≥90% (Note: For potassium-based fertilizers, the macronutrient content refers to
