Free amino acid values verified by Eurofins (CNAS-accredited) using GB/T 18246-2019 analysis — Cert. No. AR-26-Y3-008791-02, issued 29-Apr-2026. Total free amino acids: 75.37%. Glycine and proline rich — natural chelation and stress resistance.
| Amino Acid | Content |
|---|---|
| Glutamic Acid | 12.13% |
| Glycine | 11.56% |
| Serine | 10.04% |
| Aspartic Acid | 7.97% |
| Proline | 7.92% |
Typical use rates for high-concentration formulations. Lower inclusion rates deliver the same active content as higher-volume grades.
| Application Method | Typical Rate |
|---|---|
| Foliar spray | 50 – 150 g per 100 L water (0.05 – 0.15%) |
| Fertigation / drip | 1 – 2 kg per hectare per application |
| High-strength biostimulants | 20 – 50% of finished concentrate |
| Specialty liquid formulations | Per target concentration |
| Seed treatment | 0.05 – 0.1% solution |
Rates vary by crop, growth stage and formulation target — our agronomy team provides crop-specific recommendations on request.
≥ 80% total amino acids means more actives per kilo — lower freight, lower inclusion rates, higher formulation value.
Glycine is the smallest amino acid — a natural chelating agent that complexes micronutrients. Proline drives osmotic stress resistance.
Independently confirmed by Eurofins — free amino acids are immediately plant-available.
