JINMAI-Black Soil Energy® is a next-generation fulvic and humic acid–based biostimulant derived from high-quality lignite through advanced solubilization and activation technology. With its low molecular weight fulvic acid fraction, the product demonstrates exceptional solubility, permeability, and bioactivity—ensuring rapid nutrient absorption through both roots.
Beyond nutrient transport, the formula is enriched with balanced nitrogen (N) and potassium (K₂O), offering a dual role:
1. Soil conditioning – restructuring compacted soils, improving aeration and water retention, and stimulating beneficial microbial activity.
2. Plant stimulation – enhancing root architecture, boosting nutrient mobility, and strengthening stress tolerance.
The result is improved soil fertility, healthier root systems, and higher crop yield and quality across a wide range of agricultural systems. Especially suitable for arid sandy soils such as Hami melon cultivation areas, where root wilting and weak soil structure often limit production. By improving soil moisture retention and strengthening root vitality, this product provides a practical solution to melon wilt and drought stress.

Application Guidelines
Application Method | Dosage | Frequency |
| Root Drip Irrigation | 1–2 L/ha (Dilution 1:500–800) | Every 15–20 days during growth |
| Soil Drenching | 1 L/ha (Dilution 1:300–500) | Pre-planting or early growth |
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.
Best Timing of Use
Pre-Planting: To enhance soil structure and increase organic matter content.
Early Growth: Promotes seedling vigor and strong root establishment.
Vegetative Stage: Improves nutrient uptake and canopy development.
Fruit Expansion & Maturation: Enhances nutrient transport and fruit quality.
High-Temperature & Drought Conditions: Recommended for use during hot and dry weather to alleviate wilting, reduce stress damage, and maintain stable growth, especially in sandy soils such as Hami melon plantations.
