Amino Oligopeptide Organic Potassium Fertilizer​

JINMAI-Full Strength® Amino Oligopeptide Organic Potassium Fertilizer is a high-performance liquid potassium biostimulant specifically designed for the fruit expansion and ripening stages of crop development. The formula combines 100 g/L amino acids, 200 g/L organic potassium, organic matter, and micronutrients boron and zinc, providing a powerful nutrient complex that promotes fruit enlargement, improves coloration, and enhances sweetness.

During the fruit development stage, crops require a high level of potassium and bioactive nutrients to support carbohydrate synthesis and nutrient transport. JINMAI-Full Strength® addresses this demand by delivering readily available organic potassium and amino oligopeptides that stimulate metabolic activity and improve the efficiency of nutrient absorption.

The presence of natural plant-derived biostimulants and chelated trace elements enhances photosynthetic efficiency and supports the transport of sugars from leaves to developing fruits. This results in larger fruit size, higher soluble sugar content, improved flavor, and more uniform coloration.

By combining high potassium nutrition with amino acid biostimulation, this fertilizer helps growers maximize fruit quality, yield potential, and market value.

Our Advantages

Our Amino-Oligopeptide Organic Potassium Fertilizer combines high-efficiency potassium with bioactive peptides to maximize nutrient uptake and utilization. This advanced formulation ensures optimal potassium delivery—critical for fruit quality and plant health—while supporting overall metabolic functions through organic amino acid complexes.

• Superior Potassium Absorption

The oligopeptide complex increases potassium uptake efficiency by 30–40% compared to inorganic potassium fertilizers. This results in rapid translocation to fruits and reproductive organs where potassium demand is highest .

• Quality Parameter Enhancement

Elevates fruit sugar content by 1–2° Brix and improves texture through enhanced cell wall formation. Treated crops exhibit reduced physiological disorders, with blossom-end rot in tomatoes decreasing by up to 60% .

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

• Pre-Fruit Expansion Stage: Prepare plants for rapid growth and sugar accumulation.

• Fruit Expansion Stage: Boost cell division and sugar transport for bigger fruits.

• Coloring Stage: Enhance pigment synthesis for brighter, market-ready fruits.

• Pre-Harvest: Maintain sweetness and firmness for better storage and transport.

FAQ

1. Why is potassium important for fruit development?

Potassium regulates carbohydrate transport within plants and supports enzyme activation. Adequate potassium supply improves fruit size, sweetness, firmness, and overall quality.

2. What are amino oligopeptides and how do they help crops?

Amino oligopeptides are small peptide molecules derived from proteins. They are easily absorbed by plants and act as metabolic stimulants that improve nutrient uptake and plant growth efficiency.

3. When should growers apply potassium fertilizers for best results?

Potassium fertilizers are most effective during the fruit expansion and ripening stages, when crops require high energy and carbohydrate transport for fruit development.

4. Can this product be mixed with other fertilizers?

Yes. JINMAI-Full Strength® is compatible with most water-soluble fertilizers and crop protection products. However, a small compatibility test is recommended before tank mixing.

5. Will this fertilizer improve fruit sweetness?

Yes. The high potassium and amino acid content enhances sugar synthesis and transport, resulting in higher soluble sugar content and improved fruit flavor.

6. Is this product suitable for greenhouse crops?

Yes. The fully water-soluble formula makes it ideal for greenhouse fertigation systems and foliar spray applications.
