Micronutrient Fertilizers: What Buyers Should Know
Micronutrient fertilizers supply the trace elements iron (Fe), zinc (Zn), manganese (Mn), copper (Cu), boron (B), and molybdenum (Mo) that crops need in small but essential amounts. Buyers source micronutrient fertilizers from China as chelated powders and granules that correct deficiencies in alkaline soils, orchards, and horticultural crops.
The key specifications are chelation type, element content, water solubility, and application form. EDDHA chelates stay stable at high pH, while EDTA and sulfates are more economical. The curated suppliers below are screened against these criteria.

7 Checks Before Choosing a Micronutrient Fertilizers Supplier
1. Chelation type
EDDHA iron works in high-pH soils; EDTA and sulfates are more economical elsewhere.
2. Element content
Verify the guaranteed percentage of each micronutrient on the certificate.
3. Solubility
Fully soluble chelates prevent dripper clogging and foliar residue.
4. Ortho-ortho content
For EDDHA iron, confirm the ortho-ortho isomer fraction for stability.
5. Granule form
Choose granules for soil application and fine powder for foliar sprays.
6. Heavy metals
Request heavy-metal test reports for import compliance.
7. Packaging
1kg to 25kg bags; confirm moisture-proof packaging for hygroscopic products.
Frequently Asked Questions
What are micronutrient fertilizers?
They supply essential trace elements such as iron, zinc, manganese, copper, boron, and molybdenum that crops need in small amounts.
What is chelated iron fertilizer?
Chelated iron keeps iron soluble and available in the soil; EDDHA chelates remain stable in alkaline soils.
How do I know if my crop needs micronutrients?
Soil tests and visible deficiency symptoms such as yellowing leaves can identify which micronutrient is lacking.
What is the MOQ for micronutrient fertilizers from China?
Typically 5-10 metric tons; see each supplier profile for exact MOQ and formulation options.
