T/GVEAIA 003.4-2019 Drug and food origin standards - Inputs - Part 4: Biologically-enhanced inorganic blend fertilizer

Scope

Scope: This standard specifies the terms and definitions, requirements, test methods, inspection rules, labeling, packaging, transportation, and storage for bio-organic-inorganic compound fertilizers. This standard applies to bio-organic-inorganic compound fertilizers made by mixing bio-agents, organic fertilizers, mineral fertilizers, and chemical fertilizers into powders or granules. The mixing materials must contain at least bio-agents and one or more other materials. Main technical content: - Organic matter percentage (%)：First grade 0.0; Second grade 0.0-30.0; Third grade 30.0-50.0. - Fungal spore powder percentage (%)：First grade 0.1; Second grade 0.1-0.15; Third grade 0.15A. - Total nutrient (N+P2O5+K2O) content (%)：First grade 35.0-45.0; Second grade 15.0-35.0; Third grade 5.0-15.0. - Water-soluble phosphorus as a percentage of total phosphorus (%) ≥ 60; Second grade 60; Third grade 60. - Moisture content (H2O) (%) ≤ First grade 30; Second grade 15; Third grade 2.0. - Particle size (1.00mm～4.75mm or 3.35mm～5.60mm) (c) (%) ≥ First grade 90; Second grade 90; Third grade 90. - Powder fineness (passing 0.50mm sieve) (%) ≥ First grade 80; Second grade 80; Third grade 80. - pH value: 3.1～7.5 - Chloride ion content (%)：Products not labeled "chloride-free" ≤ 3.0, products labeled "chloride (low chloride)" ≤ 15.0, products labeled "chloride (medium chloride)" ≤ 30.0. - Arsenic and its compounds (as As) ≤ 0.0050% - Cadmium and its compounds (as Cd) ≤ 0.0010% - Lead and its compounds (as Pb) ≤ 0.0200% - Chromium and its compounds (as Cr) ≤ 0.0500% - Mercury and its compounds (as Hg) ≤ 0.0005%
