Amino 80 is a water-soluble powder containing at least 80% total amino acids — the highest-concentration grade of compound amino acid fertilizer. It is produced by hydrolysis of protein sources such as duck feathers or soy and is used to formulate high-strength biostimulants, low-volume foliar sprays, fertigation programs and specialty liquid concentrates where maximum amino acid density per kilogram matters.

What is Amino 80 made from?

Amino 80 is made by hydrolyzing protein-rich raw materials — most commonly duck feather keratin, soy protein or animal collagen — into short peptides and free L-amino acids, then concentrating and spray-drying the hydrolysate. At Everwell Bio, Amino Acids 80 is produced from hydrolyzed duck feather protein, with a verified free amino acid content of 75.37% independently tested by Eurofins.

What is the difference between Amino 45 and Amino 80?

The number is the guaranteed minimum total amino acid content: Amino 45 contains at least 45%, Amino 80 at least 80%. Amino 80 delivers nearly twice the active amino acids and organic nitrogen (≥12% vs ≥8%) per kilogram, so less product is needed per hectare and freight cost per unit of active is lower. Amino 45 is the more economical all-round grade for general foliar and soil programs; Amino 80 is preferred for high-strength biostimulant concentrates, hydroponics, post-stress rescue sprays and export formulations where shipment weight matters.

What is Amino 80 used for?

Amino 80 is used for: (1) formulating high-strength liquid biostimulants at 20–50% inclusion, (2) low-volume foliar sprays at 0.05–0.15% concentration, (3) fertigation and drip programs at 1–2 kg/ha, (4) rapid crop recovery after drought, frost, salinity or herbicide stress, (5) hydroponic and specialty nutrient formulations, and (6) seed treatment at 0.05–0.1% solution.

How do you apply Amino 80?

Amino 80 is 100% water-soluble. Apply as a foliar spray at 50–150 g per 100 L of water (0.05–0.15%), through drip irrigation at 1–2 kg per hectare per application, or include at 20–50% when formulating biostimulant concentrates. Because the concentration is high, dilution rates are roughly half those of Amino 45. Spray in early morning or late afternoon and repeat every 10–14 days during active growth.

Is Amino 80 safe for organic farming?

Yes. Amino 80 derived from hydrolyzed feather protein is a non-synthetic input produced by physical and enzymatic hydrolysis, and is accepted by most organic certification programs including EU 2018/848, OMRI and JAS. It leaves no chemical residue, adds no salt load, and is safe to apply up to harvest.

Amino Acid 80 Explained: Composition and Uses

Amino Acid 80 is a high-concentration protein hydrolysate grade specified to contain at least 80% total amino acids. It is designed for formulations where amino acid concentration, available formulation space or freight per unit of total amino acids is important.

The “80” refers to total amino acids. It does not mean that every batch contains 80% free amino acids, and it does not guarantee a stronger crop response than every lower-concentration product.

Current Everwell Bio specification

Parameter	Current published specification or result
Total amino acids	≥80%
Total nitrogen	≥12%
Organic matter	≥80%
Moisture	≤5%
pH, 1% solution	4–6
Water solubility	100%
Source	Hydrolyzed duck feather protein
Free amino acids	75.37% in a recent independently tested sample

The independently measured 75.37% free-amino-acid value is a result for the tested sample. A buyer should use the current product specification for contractual requirements and the assigned batch COA for shipment release.

Why total and free amino acids differ

A protein hydrolysate may contain free amino acids, small peptides and other soluble protein-derived components. A total-amino-acid test generally releases amino acids from peptide-bound forms during laboratory analysis. A free-amino-acid test measures amino acids that are already unbound under the stated method.

Method name, sample preparation, moisture basis and calculation basis can all affect the result. Ask the supplier and laboratory to identify them.

Where a high-concentration grade may fit

Amino Acid 80 may be considered for:

concentrated water-soluble fertilizer formulations;
foliar or fertigation products requiring a high amino acid contribution;
liquid concentrates after stability testing;
low-inclusion-rate formulations; and
export products where freight per kilogram of total amino acids matters.

On a theoretical total-amino-acid basis, 1 kg of an 80% product contains the same amount of total amino acids as about 1.78 kg of a 45% product. This calculation does not prove equivalent field performance. The free-amino-acid fraction, peptide profile, salts, pH and final application rate must also be considered.

Higher concentration is not automatically better

A higher grade can reduce the amount of powder needed to reach a formulation target, but it may also change solution behavior, osmotic load, cost and crop-safety margins. Some lower-concentration products include components that are useful in a particular formulation.

The correct comparison is not simply 45 versus 80. It is:

cost per kilogram of the required component;
verified total and free amino acids;
nitrogen and salt contribution;
solubility at the intended concentration;
compatibility with the full formula; and
crop performance at the intended dose.

Agronomic claims should be product-specific

Protein hydrolysates may support nutrient-use efficiency and crop responses to abiotic stress. The published evidence also shows substantial variation among products and application conditions. High free-amino-acid concentrations can be inhibitory in some circumstances.

Do not assume that twice the amino acid concentration produces twice the agronomic effect. Do not publish a fixed response time or guaranteed benefit without trials using the exact product and formulation.

Application testing

Amino Acid 80 is concentrated, so application rates copied from a 35% or 45% product may be inappropriate. Use the current TDS or locally approved label as the starting point. For new formulations:

confirm water quality and target solution pH;
run dissolution and filtration tests;
conduct jar tests with every planned ingredient;
test crop safety at several concentrations; and
compare performance with an untreated control under the intended conditions.

Avoid universal statements about compatibility with NPK fertilizers, calcium, phosphate, copper products or pesticides. Compatibility is concentration- and formulation-dependent.

Organic and regulatory status

Amino Acid 80 is not automatically eligible for organic farming because it is a protein hydrolysate. Acceptance depends on the exact source, process, formulation, intended use and certification program. Buyers must verify current documentation for the exact product and destination market.

Buyer checklist

Request:

current product specification;
representative and batch-specific COA;
total- and free-amino-acid methods;
total and organic nitrogen values;
sodium, chloride or other relevant salts;
pH, solubility and insoluble matter;
raw-material and hydrolysis-process statement;
SDS and storage guidance; and
a sample for bench and crop testing.

Conclusion

Amino Acid 80 is a high-concentration formulation input. Its main advantage is the amount of total amino acids delivered per kilogram, not a guaranteed field response. Buyers should qualify it through comparable analytical data and application-specific trials.
