Amino Acid Liquid Fertilizer for Crop Growth • Humic Acid, Seaweed extract, Amino acid Manufacturer

Amino Acid Liquid Fertilizer Overview

A high-concentration, bioactive amino acid liquid fertilizer crafted via enzymatic hydrolysis—designed to deliver efficient nutrient supply and support crop growth, with a bright yellow golden appearance for easy identification.

Core Advantages

Superior Process: Enzymatic hydrolysis ensures high amino acid bioavailability, making nutrients easier for crops to absorb (no complex conversion needed).
High Concentration: Total amino acid content reaches ≥500g/L (50% w/v), with a balanced ratio of peptides (45~48%) and free amino acids (2~3%)—covers both immediate and sustained nutrient needs.
Stable Performance: pH ranges from 4~6 (acidic, compatible with most crops) and density at 1.15—easy to dilute and apply via common agricultural methods.

Core Value for Crops

Efficient Nitrogen Supply: 7.5% organic nitrogen is released gently, avoiding nitrogen burn while fueling leaf growth and fruit development.
Dual Nutrient Release: Free amino acids provide quick nutrient boosts (e.g., emergency fertilization for weak seedlings), while peptides release slowly to support long-term growth (e.g., fruit expansion).
Wide Compatibility: Works for fruits, vegetables, grains, and cash crops—suitable for foliar spraying, drip irrigation, or drenching.

Application Scope

Agricultural Crops

Field Crops: Wheat, rice, corn, soybeans (Strengthen roots and seedlings at the seedling stage; improve lodging resistance and grain weight at the filling stage).

Vegetables

Open-field and greenhouse vegetables including tomatoes, cucumbers, peppers, lettuce, and broccoli. (Compatible with drip/sprinkler systems for precise fertilization)

Fruit Trees

Pome fruits (apple, pear), stone fruits (peach, cherry), citrus, grapes, and berries, Tropical & Subtropical Fruits. (Enhance fruit sweetness, coloration, and reduce deformed fruits);

* Other Scenarios: Hydroponics, substrate cultivation, lawn & landscape greening, seed treatment, nursery production, and flower farming.

Recommended Dosage & Application Methods

Adjust based on crop growth stages. The core principle is “apply after dilution to avoid burn from high concentration”.

Specific methods:

Method	Key Operation Points	Applicable Scenarios
Foliar Spraying	Dilute at 1:800~1000 (1L product + 800~1000L water); apply 300~450L of diluted solution per hectare (or 0.3~0.45L per square meter). Spray evenly on both leaf sides; avoid high temperatures (above 30℃) and alkaline pesticides (e.g., Bordeaux mixture).	Quick nutrient supplementation for weak seedlings, flowering stage (fruit retention), and fruit expansion stage (quality improvement)
Hydroponic Application	Dilute at 1:1500~2000 (1L product + 1500~2000L water); add 2~3L of diluted solution to every 100L of hydroponic nutrient solution. Stir well, monitor pH (maintain 5.5~6.5), and replace the nutrient solution every 7~10 days to avoid nutrient accumulation.	Routine nutrient supply for hydroponic systems – supports steady growth of leafy greens and herbs without soil nutrient competition

Case 2: Hydroponic Use Improves Lettuce Quality

Background: Solving high nitrate levels in hydroponic lettuce via partial inorganic nitrogen replacement.

Method: Add 1:2000 diluted product to nutrient solution (replaces 25% inorganic N); control = full inorganic N.

Results:

Vitamin C ↑22%; nitrate ↓18% (meets EU organic standards).
Root activity ↑35%; root rot rate ↓40%.

Liquid Amino Acid FAQ

1. What is liquid amino acid fertilizer?

It’s a liquid fertilizer with amino acids (500g/L content) as the core, made via enzymatic hydrolysis or synthesis. It’s absorbed directly by crops (no conversion needed) to supplement nutrients and boost stress resistance.

2. Which crops is it suitable for?

Nearly all crops, including fruits (citrus, grapes), vegetables (tomatoes, lettuce), field crops (wheat, corn), and hydroponic plants (spinach, herbs).

3. What’s the recommended dilution ratio for foliar spraying?

For most crops, dilute 1:800~1000 (1L product + 800~1000L water). Avoid high concentrations to prevent leaf burn.

4. Can it be used in hydroponic systems?

Yes. Dilute 1:1500~2000 and add to hydroponic nutrient solution. It helps maintain pH 5.5~6.5 and reduces nitrate levels in crops.

5. How long does it take to see results?

Foliar spraying shows effects in 1~3 days (e.g., greener leaves for weak seedlings); long-term effects (yield/quality improvement) take 2~4 weeks.

6. Can it be mixed with other fertilizers/pesticides?

Mix with most water-soluble fertilizers (e.g., nitrogen, phosphorus) but avoid alkaline products (pH>8, like Bordeaux mixture) – they break down amino acids.

7. Is it suitable for organic farming?

Yes, if it’s made via natural enzymatic hydrolysis (e.g., from plant/animal sources). It’s degradable, residue-free, and meets organic certification standards.

8. What if it precipitates in low temperatures?

Slight sediment below 5℃ is normal. Let it stand at room temperature and shake well – it won’t affect efficacy.

9. Can it be used in saline-alkali soil?

Yes. Dilute 1:400~500 for soil drenching; it helps lower soil pH slightly and improves crop root absorption in saline conditions.

10. What happens if I use too much?

Overuse (undiluted or under-diluted) may cause leaf edge scorching (foliar) or root damage (soil/hydroponic). Follow the dilution ratio strictly.
