II. Product Introduction
This product is manufactured from non‑GMO soybean meal / corn protein via a low‑temperature gradient enzymatic hydrolysis and membrane purification process. It represents a new generation of high‑purity plant‑based amino acid powder, specifically engineered to meet the processing demands of liquid fertilisers and water‑soluble fertiliser formulations. It outperforms traditional protein hydrolysates in four key dimensions: colour, solubility, long‑term stability, and safety.
Whether you are producing clear‑liquid macro‑nutrient fertilisers, high‑concentration foliar feeds, or drip‑irrigation drenches, this product provides a reliable and stable source of amino acid nutrition while greatly simplifying your production process – no concerns about colour darkening, no precipitate handling, and no residue worries.
III. Four Core Advantages (In‑Depth Look)
Advantage 1: Pure White Colour – Crystal‑Clear Finished Products
Conventional amino acid powders are often yellowish‑brown to dark brown, resulting in dull, dark fertiliser colours that fail to meet the market demand for "clear and transparent" liquids. This product is a fine pure‑white powder; when dissolved, it yields a colourless to pale‑yellow transparent solution, giving you full control over the final colour – ideal for producing high‑clarity, premium‑grade water‑soluble fertilisers.
Advantage 2: 20% High‑Concentration Solutions – Still Clear After Six Months
Even at a concentration of 20%, aqueous solutions of this product remain completely free of precipitation, flocculation, or stratification after more than 6 months at room temperature. This allows you to prepare concentrated stock solutions in bulk and store them for extended periods, eliminating the common headache of "make‑fresh‑and‑use‑immediately" and preventing clogging during filling and application.
Advantage 3: Balanced 18‑Amino‑Acid Profile – Synergistic Efficacy
Unlike single‑dominant or unbalanced amino acid products, this powder delivers a complete spectrum of 18 free amino acids, with notably high proportions of key stress‑relief and growth‑promoting components: glutamic acid (17.43%), alanine (10.29%), valine (10.47%), and threonine (9.46%). These amino acids directly participate in protein synthesis, osmotic regulation, and hormone signalling in plants. The multi‑component synergy ensures more comprehensive and longer‑lasting fertiliser effects.
Advantage 4: 100% Plant‑Derived + Ultra‑Low Heavy Metals – Absolute Safety
All raw materials are of plant origin, containing no hydroxyproline – fundamentally eliminating the pathogen, hormone, and allergen risks associated with animal‑based hydrolysates. Moreover, actual heavy metal levels are all below detection limits (Hg, As, Cd, Pb, Cr far below national standards), meeting EU and US organic input requirements. It is safe for use on high‑value export crops including fruits, vegetables, tea, and medicinal herbs.

VI. Typical Applications in Fertiliser Formulations
Application 1: Clear‑Liquid Macro‑Nutrient Water‑Soluble Fertilizers (N‑P‑K + Amino Acids)
-
Addition rate: 5%–15% (w/v) in liquid fertilisers; 5%–10% (w/w) in powder blends.
-
Effect: Boosts total nitrogen content and adds organic nutrients, improving the rhizosphere environment.
-
Process advantage: Dissolves directly into the N‑P‑K base solution at room temperature with simple stirring – no heating required; finished product is bright and clear.
Application 2: Amino‑Acid Chelated Secondary / Micronutrient Fertilizers
-
The carboxyl and amino groups of this product naturally chelate Ca, Mg, Zn, Fe, and Mn, enhancing micronutrient availability.
-
Compared with EDTA‑chelated forms (e.g., EDTA‑Fe, EDTA‑Zn), this product also provides nutritional benefits, is more environmentally friendly, and is cost‑effective.
Application 3: Foliar Stress‑Relief & Growth Promoter
-
Dilute 800–1200× and spray at critical growth stages (seedling, flowering, young fruit set).
-
Glutamic acid boosts photosynthesis, glycine improves cold tolerance, and alanine regulates osmotic balance – collectively enhancing resistance to drought, chilling, and salinity.
Application 4: Organic Water‑Soluble Fertilizer / Biostimulant Base
-
100% plant‑derived, meeting organic product standards. Can be used alone or blended with humic acid, seaweed extract, chitosan, and other adjuvants.
-
Suitable for high‑value cash crops such as fruits, vegetables, tea, and medicinal herbs to improve quality and yield.
Application 5: Raw Material for Export‑Oriented Speciality Fertilizers
-
Heavy metal levels satisfy the requirements of major export markets (EU, USA, Japan, etc.); with no animal‑derived residues, it helps manufacturers expand into overseas markets.
VII. Usage & Compatibility Guidelines
-
Liquid Stock Solution Preparation: Add 10–20 kg of this product to 80–90 kg of water, stir at room temperature until clear – the stock solution is stable for long‑term storage; stir before use if needed.
-
Addition to Powder Blends: Incorporate 5%–15% by total weight, mix thoroughly with other dry ingredients.
-
Foliar Spray Concentration: Dilute 800–1500× with water; apply in the early morning or late afternoon on calm, sunny days.
-
Drip Irrigation / Soil Drench Rate: Apply 0.5–1.5 kg per mu (≈7.5–22.5 kg/ha) per application, delivered with irrigation water to the root zone, at 7–15 day intervals.
-
Compatibility Precautions: Avoid prolonged contact with strongly alkaline (pH > 9) or strongly oxidising substances. When blending with calcium‑containing fertilisers, perform a small‑scale compatibility test first to rule out flocculation before bulk preparation.
VIII. Packaging & Storage
-
Packaging: 25 kg per bag, outer high‑strength kraft paper composite, inner polyethylene moisture‑barrier liner.
-
Storage: Keep in a cool, dry, well‑ventilated warehouse, away from direct sunlight. After opening, seal tightly to prevent moisture absorption and use promptly.
-
Shelf Life: 24 months from production date in original unopened packaging under recommended conditions.
