L-Amino Acid Oligopeptide Biostimulant

JINMAI® L-Amino Acid Oligopeptide Biostimulant is a high-protein, peptide-rich plant biostimulant produced from collagen protein through targeted bio-enzymatic hydrolysis. It contains a high proportion of low-molecular-weight oligopeptides and L-amino acid residues designed to provide readily available organic nitrogen and bioactive peptide fractions for crop nutrition and physiological support.

With ≥80% protein, ≥80% low-molecular-weight oligopeptides below 500 Da, and ≥50% organic matter, the product is formulated for efficient foliar and root-zone application. Its excellent water solubility and small molecular size make it suitable for modern fertigation and foliar nutrition programs.

Rather than functioning simply as a conventional nitrogen fertilizer, JINMAI® L-Amino Acid Oligopeptide Biostimulant is designed to support natural plant processes related to nutrient utilization, root development, vegetative growth, stress recovery, fruit development, and crop quality.

Method of Use

Note: The specific usage and dosage can be adjusted according to the differences in regions, crop types, yields, etc, under the advice of technical personnel.

Optimal Application Timing

• Seedling & Transplanting: Supports root establishment, fibrous root development and recovery from transplanting stress.

• Vegetative Growth: Promotes root and shoot growth, nutrient utilization and overall crop vigor during active growth.

• Pre-Flowering & Flowering: Supports reproductive development, plant vigor and nutrient supply during the transition to flowering.

• Fruit Setting & Enlargement: Supports nutrient transport, fruit development, fruit size and quality potential during key reproductive stages.

• Stress Recovery & Post-Harvest: Helps crops recover from heat, drought, salinity or other environmental stresses, while supporting renewed growth after harvest.

Precautions

1. Store sealed in a dry, cool, and well-ventilated place, away from heat, moisture, and direct sunlight.

2.Reseal promptly after opening and use as soon as possible to prevent moisture absorption, caking, and loss of activity.

3. Dilute thoroughly before application and conduct a compatibility test before mixing with other agricultural inputs.

4. Adjust dosage and frequency according to crop type, growth stage, and local growing conditions.

FAQs

1. What is a peptide biostimulant?

A peptide biostimulant is a plant biostimulant containing bioactive peptides, amino acids and other protein-derived compounds. These substances can support natural plant processes associated with nutrient utilization, growth, stress response and crop quality.

2. What is the difference between amino acids and oligopeptides?

Amino acids are individual building blocks of proteins, while oligopeptides consist of short chains of amino acids. JINMAI® combines both peptide-derived and amino acid components, with a particularly high proportion of low-molecular-weight oligopeptides.

3. Why are peptides below 500 Da important?

Small peptide molecules are highly soluble and suitable for foliar and root-zone application. The high proportion of peptides below 500 Da is one of the key characteristics differentiating this product from conventional protein-based organic fertilizers.

4. Can it be used with NPK fertilizers?

Yes. It can be incorporated into an integrated crop nutrition program alongside compatible NPK fertilizers and micronutrients. It is intended to complement mineral nutrition rather than replace the crop's primary NPK requirements.

5. Can it be applied during crop stress?

Yes. The product can be incorporated into a crop recovery program before or after heat, drought, salinity, transplanting or other environmental stress. Application timing and dosage should be adjusted according to crop condition.

6. Is it suitable for fertigation?

Yes. Its 100% water solubility makes it suitable for drip irrigation and fertigation systems when properly dissolved and filtered.
