Water-soluble amino acid powders are used in foliar fertilizers, fertigation products and compound nutrient formulations. The appropriate grade depends on the required amino acid concentration, nitrogen contribution and formulation cost.
AA35, AA45, AA50 and AA80: What Is the Difference?
| Grade | Total Amino Acids | Typical Positioning |
|---|---|---|
| AA35 | 35% | Cost-efficient general crop nutrition |
| AA45 | 45% | Balanced concentration for foliar and soil application |
| AA50 | ≥50% | Concentrated fertilizer formulations |
| AA80 | ≥80% | High-strength professional formulations |
All four grades are designed as water-soluble powders. Higher concentration allows formulators to deliver more amino acids with less material, while lower grades may offer greater cost flexibility.
Key Selection Factors
Buyers should compare more than the grade name. Important specifications include:
- total and free amino acid content;
- total nitrogen and organic matter;
- moisture, pH and water solubility;
- raw-material origin and hydrolysis method;
- compatibility with other formulation ingredients.
For foliar spray or drip irrigation, a dissolution and compatibility test should be completed before large-scale use. The final dosage should reflect crop type, growth stage, climate and local agronomic practice.
