Amino 80 is a water-soluble powder containing at least 80% total amino acids — the highest-concentration grade of compound amino acid fertilizer — used to formulate high-strength biostimulants, low-volume foliar sprays and specialty crop nutrition programs in agriculture. It delivers nearly twice the active amino acids per kilogram of the popular Amino 45 grade.
This guide explains what Amino 80 is made of, how it differs from Amino 35 and 45, where its high concentration pays off most, and how to apply it correctly. It is written for fertilizer formulators, biostimulant blenders, agronomists and distributors evaluating a maximum-density amino acid source.
What is Amino 80?
Amino 80 is a fine, light-yellow to brown powder containing at least 80% total amino acids on a dry-weight basis, together with ≥12% total nitrogen and ≥80% organic matter. It is the top grade in the standard 35 / 45 / 80 compound amino acid product range.
It is produced by hydrolysis of protein-rich raw materials — most commonly duck feather keratin, soy protein or animal collagen. Long protein chains are broken into short peptides and free L-amino acids, then the hydrolysate is concentrated and spray-dried into a free-flowing powder that dissolves 100% in water with no residue.
Because the amino acids are in free L-form, plants absorb them directly through leaf cuticles and root membranes within hours — bypassing the mineralisation step required by conventional nitrogen fertilisers. At 80% concentration, one kilogram of Amino 80 carries the same active payload as roughly 1.8 kg of Amino 45, which is why it is the preferred grade when formulation density, freight cost or inclusion rate matters.
Quality verification matters at this concentration: our Amino Acids 80 grade has been independently tested by Eurofins, confirming 75.37% free amino acids out of the ≥80% total amino acid content.
Composition of Amino 80
The table below is the typical specification for an Amino Acids 80 grade produced from hydrolyzed duck feather protein (our reference product at Everwell Bio):
| Parameter | Specification |
|---|---|
| Total amino acids | ≥ 80% |
| Total nitrogen | ≥ 12% |
| Organic matter | ≥ 80% |
| Free amino acids (Eurofins verified) | 75.37% |
| Moisture | ≤ 5% |
| pH (1% solution) | 4 – 6 |
| Water solubility | 100% |
| Appearance | Light yellow to brown powder |
| Source | Hydrolyzed duck feather protein |
Typical amino acid spectrum (verified by third-party laboratory analysis):
| Glutamic acid | 12.13% |
| Glycine | 11.56% |
| Serine | 10.04% |
| Aspartic acid | 7.97% |
| Proline | 7.92% |
| Leucine, alanine, valine, arginine, lysine and others | balance |
The spectrum is naturally rich in glycine and glutamic acid — the two amino acids most involved in chlorophyll synthesis and micronutrient chelation — and in proline and serine, the key osmoprotectants that help crops maintain turgor under drought and salinity stress.
How Amino 80 Works in the Plant
Amino 80 works through the same three mechanisms as all free-amino-acid biostimulants — but at roughly double the intensity per gram applied:
- Direct protein synthesis. Free L-amino acids are absorbed through leaves and roots and assembled directly into plant proteins, enzymes and chlorophyll, saving the plant significant metabolic energy compared with synthesising amino acids from mineral nitrogen.
- Natural chelation. Glycine, glutamic acid and aspartic acid bind Fe, Zn, Mn, Cu and Ca into organic complexes that cross leaf and root membranes far more efficiently than free mineral ions — improving micronutrient translocation.
- Stress osmoregulation. Proline, serine and glycine-betaine accumulate in cells as osmolytes, protecting membranes and enzymes during heat, drought, frost, salinity and herbicide stress, and accelerating recovery afterwards.
Benefits of Amino 80
Applied at the right rate and stage, Amino 80 delivers:
- Maximum actives per kilo. More than 800 g of amino acids per kg of product — lower inclusion rates, less packaging, lower freight cost per unit of active.
- High-strength formulation capability. Stable at 20–50% inclusion in liquid biostimulant concentrates without precipitation or caking.
- Rapid stress recovery. The concentrated proline and glycine fraction makes it the grade of choice for rescue sprays after frost, hail, heat waves or herbicide phytotoxicity.
- Low-volume application. At 0.05–0.15% dilution, full-rate amino nutrition fits into low-volume spray programs and UAV/drone spraying.
- Enhanced NPK efficiency. Tank-mixed with NPK solutions, it raises apparent nutrient utilisation, especially under cold-soil or root-restricted conditions.
- Clean, residue-free. 100% water-soluble, no clogging of drip lines or spray nozzles, no salt build-up, no residue on produce.
Application: How to Use Amino 80
Amino 80 is fully water-soluble. Because the concentration is high, dilution rates are roughly half those used for Amino 45:
| Method | Dilution / Rate | Frequency | Best timing |
|---|---|---|---|
| Foliar spray | 50 – 150 g per 100 L water (0.05 – 0.15% w/v) | Every 10 – 14 days | Early morning or late afternoon |
| Fertigation / drip | 1 – 2 kg / ha per application | Every 14 – 21 days during active growth | Early in the irrigation cycle |
| Biostimulant concentrate | 20 – 50% of finished concentrate | Per formulation | Blend with humic, seaweed or NPK bases |
| Seed treatment | 0.05 – 0.1% solution | Once before sowing | Coat seed and dry before planting |
Compatibility. Amino 80 is compatible with most NPK solutions, micronutrients, humic acid, seaweed extract and common crop-protection products. Avoid tank-mixing with strongly alkaline products (pH > 8) or concentrated copper fungicides; always jar-test before first commercial use.
Where Amino 80 Excels
- Biostimulant & specialty formulation — the core use case: maximum amino density for premium liquid and soluble products.
- High-value crops — grapes, berries, citrus, avocado, protected vegetables, golf and sports turf, where quality parameters (Brix, colour, firmness, shelf life) drive revenue.
- Stress-rescue programs — rapid recovery after frost, heat, salinity or herbicide damage.
- Hydroponics & fertigation — clean, fully soluble nitrogen source for soilless systems.
- Export-oriented supply chains — lower weight per unit of active reduces sea-freight cost to distant markets.
Amino 35 vs 45 vs 80: How to Choose
The number on the bag is the guaranteed minimum total amino acid content. Choose by application method and value per hectare:
| Grade | Total amino acids | Best for |
|---|---|---|
| Amino 35 | ≥ 35% | Bulk soil application, base fertilisation and large-area field crops where cost per hectare is the main driver. |
| Amino 45 | ≥ 45% | The balanced all-round grade for foliar feeding, drip irrigation and fertigation on fruits, vegetables, tea and turf. |
| Amino 80 | ≥ 80% | High-strength biostimulant concentrates, low-volume foliar programs, hydroponics, stress-rescue sprays and weight-sensitive export formulations. |
| Protein Powder | n/a (peptide-rich) | Slow-release organic base. Releases amino acids gradually through microbial mineralisation. |
