Amino Oligosaccharide Peptide Liquid
Peptides Plus Oligosaccharides — Nutrition and Plant Activation in One Pass
Total amino acid ≥ 500 g/L
Free amino acid ≥ 200 g/L
pH 5.0 – 7.0
Every lot ships with a Certificate of Analysis stating tested total amino acids, free amino acids, total nitrogen and chloride.
Product Overview
Amino acids are the building blocks of proteins and, in free form, the most readily absorbed nitrogen source a plant or an animal can take up. JINGFENG’s amino acid range is produced from plant protein (soybean) or animal protein by acid or enzymatic hydrolysis, which breaks the protein chain down into free amino acids, short peptides and water-soluble nitrogen. The result is a 100% water-soluble input used as a foliar and fertigation biostimulant, a chelating agent for trace elements, and a feed-grade protein source.
Amino Oligosaccharide Peptide Liquid is the most active product in our amino acid range — a brown, viscous concentrate that combines nutrition with plant activation. One litre carries ≥ 500 g/L total amino acids, made up of ≥ 200 g/L free amino acids and ≥ 300 g/L of peptides and small peptides, plus ≥ 100 g/L oligosaccharides and 30% organic carbon.
The oligosaccharides are the difference. They are the signal molecules that a plant recognises during a pathogen attack, so applying them triggers the same defence response without the infection: enzyme activity rises, the plant’s own repair and anti-disease systems come up, and nutrient uptake becomes more efficient. That is why the product is described as a biological activator rather than a fertiliser.
The practical results are the ones growers chase — less flower and fruit drop, stronger roots and seedlings, better disease and stress tolerance, and higher quality at harvest. At pH 5 to 7 it is mild enough for crops, soil and beneficial microbes, and long-term use improves soil condition.
Key Benefits
≥ 500 g/L total amino acids
Half a kilogram of amino acids in every litre — ≥ 200 g/L free and ≥ 300 g/L as peptides — plus ≥ 100 g/L oligosaccharides and 30% organic carbon.
No dissolving step
Supplied ready to dilute, which saves a mixing stage in fertigation and spray programmes.
Metering accuracy
A uniform liquid is easy to dose precisely, batch after batch.
High load per litre
Concentrated grades carry a high amino acid load per litre, which keeps freight cost per unit of active down.
Mixes with most inputs
Compatible with common foliar fertilisers and, after a jar test, with many agrochemicals.
COA on every batch
Each lot ships with a Certificate of Analysis stating the tested total and free amino acids, peptide fraction, oligosaccharides and organic carbon against the stated Chinese industry standards.

Form & Solubility
Form: a concentrated liquid supplied in drums or IBCs, ready to dilute and meter without a dissolving step.
In water: miscible with water in any proportion, so it can be injected straight into a fertigation line or dosed into a spray tank.
Handling: store upright and frost-free. Rinse lines with clean water after use.
Why oligosaccharides matter. Oligosaccharides are short carbohydrate chains that plants read as a signal. They are released from cell walls during a fungal or bacterial attack, and the plant responds by switching on its defence chemistry. Applying them does the same thing without the disease: enzyme systems come up, metabolism runs faster, and the plant tolerates stress better. Combining them with peptides and free amino acids means the activation and the nutrition arrive together.
Handling. It is viscous, so shake vigorously before use to distribute the active fraction evenly. Avoid strongly acidic products below pH 4 and strongly alkaline ones above pH 10, do not spray above 30 °C, and reapply if rain falls within four hours.

Frequently Asked Questions
How is this different from a normal amino acid fertiliser?
A normal amino acid fertiliser supplies nutrition. This one supplies nutrition and activation: the oligosaccharides are signal molecules that switch on the plant’s own defence and enzyme systems, the peptides carry their own physiological activity, and the organic carbon feeds the soil biology. Instead of only feeding the plant, it makes the plant work better.
When should I apply it to stop flower drop?
The windows are bud formation, early flowering and petal fall. One foliar application at each stage at 1:1000 to 1:1200, seven to ten days apart, is the schedule most of our growers use; many report flower drop cut by half or better.
Can I use it during full bloom without harming bees?
Yes. It is mild and non-toxic to pollinators when used as directed. Spray early in the morning before bees are active or late in the evening, and stay inside the 1:1000 to 1:1500 foliar range.
Any compatibility issues when tank-mixing?
It works with most neutral and weakly acidic fertilisers and pesticides. Strong acids below pH 4 and strong alkalis above pH 10 break down the peptides and oligosaccharides — the quick test is to mix 100 mL of each and use it only if nothing precipitates or discolours in 30 minutes.
What if the liquid thickens in the drum?
That is normal for a viscous concentrate. Shake vigorously before use; thickening does not reduce the nutrient content or the effect.
How long does it keep and how should it be stored?
24 months from production, kept at 5 to 35 °C in a cool, dark, ventilated place away from direct sun. Do not stack containers upside down and seal the cap tightly after each use.
Do you offer samples, and what is the minimum order?
A free 1 L sample is available with a small-plot trial guide — you cover the express cost, and it ships within two working days. Bulk MOQ is 500 L, with 5 to 10% volume discounts above 5000 L.
Can the formula be adjusted for my market?
Yes — full OEM and ODM service. The amino acid, peptide and oligosaccharide levels can be tuned to your crops and disease pressure, and packaging from 1 L to 200 L can carry your own brand and label.
