Amino Acid Fertilizers: What Buyers Should Know
Amino acid fertilizer is a plant biostimulant made from hydrolyzed plant or animal protein, delivering readily absorbed amino acids that boost stress tolerance and nutrient uptake. Buyers source amino acid fertilizers from China as soluble powder and liquid, often chelated with trace elements for foliar and drip application.
The key specifications are amino acid content, free amino acid level, mineral chelation, and solubility. Source quality affects purity and odor. The curated suppliers below are screened against these criteria.

7 Checks Before Choosing a Amino Acid Fertilizers Supplier
1. Amino acid content
Confirm total and free amino acid percentage on the certificate.
2. Source
Plant-derived (soy) hydrolysates are common; animal-derived may differ in profile.
3. Chelation
Check chelated Ca, Fe, Zn, or B for combined nutrition programs.
4. Solubility
Fully soluble powder suits foliar and drip systems without clogging.
5. Odor & color
Light color and low odor indicate cleaner hydrolysis and refining.
6. Compatibility
Verify tank-mix compatibility with pesticides and other fertilizers.
7. Packaging
1kg to 25kg bags or liquid drums; confirm shelf life for liquids.
Frequently Asked Questions
What is amino acid fertilizer?
It is a biostimulant made from hydrolyzed protein that supplies ready-to-use amino acids and chelated minerals to improve growth and stress tolerance.
How is amino acid fertilizer applied?
It is typically applied as a foliar spray or through drip fertigation at low dilution rates.
What are chelated amino acid fertilizers?
They combine amino acids with minerals like calcium, iron, or zinc for better absorption and transport inside the plant.
What is the MOQ for amino acid fertilizer from China?
Usually 5-10 metric tons for powder; see each supplier profile for liquid drum MOQ.
