Product overview
Amino acid fertilizer concentrate is produced by enzymatic or acid hydrolysis of plant and animal protein feedstocks — soybean meal, corn gluten, fish hydrolysate and feather meal — yielding a profile of L-amino acids that plants can absorb without the metabolic steps required for inorganic nitrogen assimilation. At 45% total amino acids, the concentrate delivers both organic nitrogen and biostimulant activity in a single water-soluble input suited to high-value horticulture, protected cropping and export-quality fruit programmes.
Foliar application is the primary route: amino acids penetrate leaf cuticles within hours, supporting photosynthesis recovery after heat stress, salinity shock and transplant setback. Fertigation buyers inject dilute solutions through drip systems to maintain root-zone amino acid pools during flowering and fruit set. Liquid-fertilizer compounders blend the powder into seaweed-kelp formulations, humate complexes and micronutrient packages sold to greenhouse operators, vineyard managers and turf professionals who need rapid crop response without increasing mineral salt load in the root zone.
Supply origins include enzymatic hydrolysis plants in China, Southeast Asia and Eastern Europe processing agricultural by-products into spray-dried powder and concentrated liquid grades. The L-isomer profile — glutamic acid, glycine, proline and aspartic acid as dominant fractions — chelates iron, zinc and manganese in alkaline irrigation water and acts as an osmoprotectant under drought, reducing the need for separate stress-management inputs in integrated nutrition programmes.

Loading ports & logistics
Amino acid fertilizer concentrate ships as non-hazardous organic fertilizer input under IMDG general cargo rules. Powder grades are hygroscopic — PE-lined bags and container desiccants are standard to prevent caking during transit through humid ports.
FOB from Black Sea container terminals and MENA repackaging hubs. Standard parcel: 24 MT per 20-foot container (25 kg PE-lined PP woven bags, palletised) or 100–300 MT FIBC parcels on coaster vessels for regional blending plants. Liquid concentrate (40–50% solids) loads in 200 L drums or 1,000 L IBC totes for formulation factories near destination ports.
CFR/CIF to South Asia (Nhava Sheva, Mundra, Karachi), East Africa (Mombasa, Dar es Salaam), Middle East (Jeddah, Jebel Ali) and Mediterranean horticulture ports. Lead time 10–22 days from contract to loading window, subject to hydrolysis plant capacity and spray-dryer scheduling at origin.
Packaging & documentation
Standard export pack: 25 kg PE-lined PP woven bags, palletised (40 bags per pallet) and stretch-wrapped for container loading. One-tonne FIBC big bags with moisture-barrier liner available for inland blending plants and liquid-fertilizer factories. Liquid concentrate ships in 200 L HDPE drums (16–18 drums per pallet) or 1,000 L composite IBC totes for direct-to-tank delivery at formulation sites.
Each lot includes mill certificate of analysis (total amino acids, free amino acids, total N, moisture, water solubility, pH, chloride), commercial invoice, packing list and bill of lading. Certificate of origin, phytosanitary clearance where required by destination customs, and third-party inspection at loading (SGS, Bureau Veritas) available for LC-backed contracts. SDS per GHS and amino acid profile chromatogram supplied on request.
FAQ
How do amino acid fertilizers differ from conventional nitrogen sources?
Amino acid fertilizers deliver nitrogen in organic peptide form rather than as nitrate or urea. Plants absorb L-amino acids directly through leaves and roots without the energy cost of inorganic N conversion, which speeds recovery from abiotic stress. The nitrogen content is lower per tonne than urea, but amino acids also act as chelating agents and osmolytes — buyers use them as biostimulants alongside mineral NPK rather than as a full nitrogen replacement.
What application rate suits foliar spray versus fertigation?
For foliar application, dilute powder or liquid concentrate to 0.1–0.3% (1–3 g/L) and spray at 200–400 L/ha during cool morning or evening hours. In fertigation, inject at 0.05–0.15% in the irrigation stream (0.5–1.5 g/L) every 7–14 days during vegetative growth and post-stress recovery. Reduce rates on young seedlings and increase interval on chloride-sensitive crops when paired with saline irrigation water.
Can amino acid concentrate be tank-mixed with water-soluble NPK and micronutrients?
Yes — amino acids are compatible with nitrate-based soluble NPK, calcium nitrate and EDTA-chelated micronutrients in separate stock tanks or sequential injection. Avoid combining concentrated amino acid solution with strongly alkaline or copper-based fungicides in the same spray tank; perform a jar test before field mixing. For phosphate-heavy programmes, apply amino acids in alternate passes to prevent complexation losses in hard-water systems.
