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.
Concentrated Amino Acid Liquid 30% is the volume-efficient grade of our liquid range. One litre carries a minimum of 300 g of total amino acids, so the volume you have to haul, store and meter per hectare is well below a dilute liquid — which is what decides the economics once a programme is measured in thousands of litres.
It is an acid hydrolysate, dark brown and dense at 1.20 – 1.22, carrying ≥ 7% total nitrogen alongside the amino acids and a full spectrum of eighteen free amino acids. Used on its own or blended with macro-, secondary- and micro-nutrients, it raises tolerance to cold, heat, drought and waterlogging.
One thing to check before you specify it: this grade is hydrolysed with hydrochloric acid and carries 9 – 11% chloride. That is normal and safe for cotton, grain and most field and vegetable crops at the recommended dilutions, but it is the wrong grade for strawberries, tobacco or grapes — use our salt-free 30% amino acid liquid there.
Key Benefits
≥ 300 g/L total amino acids
A concentrated grade: every litre carries at least 300 g of amino acids plus ≥ 7% total nitrogen, so less volume has to be hauled, stored and metered per hectare.
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 amino acids, free amino acids, total nitrogen, chloride and heavy metals 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.
About the chloride. This grade is a hydrochloric-acid hydrolysate and carries 9–11% chloride. At the recommended dilutions that is safe for cotton, grain and most field and vegetable crops, but it is not the grade for strawberries, tobacco or grapes. For those crops, specify our salt-free 30% amino acid liquid.
Handling. The liquid thickens slightly as it stands — natural amino acid polymerisation, not spoilage. Stir it well before use; thickening does not reduce the nutrient content or the effect.

Frequently Asked Questions
How is this different from a non-concentrated amino acid liquid?
Density. At 300 g/L or more of total amino acids, this grade carries a higher load per litre than the 100–200 g/L typical of non-concentrated liquids, so you use 20–30% less volume per hectare. That is what makes it the economical choice for large-scale programmes.
Does the 9–11% chloride content affect crops?
At the recommended dilutions, no — that level is within the safe range for most crops, particularly field crops such as cotton and grain. It does cause chloride toxicity on sensitive crops, so for strawberries, tobacco and grapes choose our salt-free 30% liquid instead.
Is it suitable for organic farming?
It is made from natural raw materials with no synthetic additives. Whether it is accepted in your programme depends on the certifier and on the chloride level they allow, so confirm with your certification body.
Can I use it on young seedlings?
Yes. Use the weaker end of the foliar range (around 1:1500) and test a small area first — it lifts seedling vigour without causing stress or burn.
When is the best time to apply it for flower and fruit retention?
Once or twice during early flowering, at 1:1000 to 1:1200 as a foliar spray. That is when it does the most for pollen viability and for reducing physiological flower drop.
Can I mix it with pesticides?
It is compatible with most neutral and weakly acidic pesticides. Avoid strongly alkaline products above pH 8, and test compatibility by mixing 100 mL of diluted liquid with the pesticide — use it only if nothing precipitates.
What if the liquid thickens over time?
That is normal — natural amino acid polymerisation. Stir it vigorously with water before use; thickening does not reduce the nutrient content or the effectiveness.
Do you offer samples, and what is the minimum order?
A 1 L sample is available; you cover the express cost and we dispatch within two working days with a short trial guide. Bulk MOQ is 500 L, with 5–8% volume discounts above 5000 L.
How is it packed and how long does it keep?
Supplied in 200 L drums and 1000 L IBCs, with 1 L, 5 L and 20 L packs for trials. Shelf life is 24 months from production when stored cool, dry and sealed; store upright and frost-free, and rinse lines with clean water after use.
