JINMAI-Black Soil Energy® Woody Peat Soil Improvement Liquid is a high-performance soil conditioner and liquid fertilizer derived from premium woody peat resources. Through an advanced extraction and activation process, the product retains a high concentration of mineral humic acid and biologically active fulvic acid, delivering powerful soil improvement and plant growth benefits.
The formula integrates balanced NPK nutrients, organic matter, and humic substances, creating a dual-function solution that enhances both soil health and crop productivity. Humic substances improve soil structure, stimulate beneficial microbial activity, and increase nutrient retention, while the NPK nutrients support vigorous crop growth and fruit expansion.
With its fully water-soluble liquid formulation, the product can be easily applied through drip irrigation, fertigation, or root irrigation systems, ensuring rapid nutrient availability and efficient absorption by plant roots.
By improving soil fertility, stimulating root growth, and optimizing nutrient utilization, this woody peat-based liquid fertilizer helps growers achieve healthier soil ecosystems, stronger crops, and higher yields.

Key Features
Product Efficacy
⦁ Improves Soil Structure and Fertility
Humic acid promotes the formation of soil aggregates, improving soil aeration, water retention, and overall soil structure. This helps restore compacted or degraded soils and supports long-term soil productivity.
⦁ Reduces Soil Salinity and Acidity Stress
Regular application increases soil organic matter and encourages beneficial microbial activity, helping buffer soil pH and reduce the negative effects of salinity or acidification.
⦁ Promotes Strong Root Development
Humic and fulvic acids stimulate root elongation and branching, allowing plants to explore a larger soil volume and absorb nutrients more efficiently.
⦁ Enhances Nutrient Utilization
The combination of organic and inorganic nutrients improves fertilizer efficiency by reducing nutrient loss and improving plant uptake of nitrogen, phosphorus, potassium, and trace elements.
⦁ Supports Crop Growth and Fruit Expansion
Balanced nutrients and humic substances promote vigorous vegetative growth, improve flowering performance, and support better fruit enlargement and yield formation.
Applications
 | Fruit Trees ⦁ Suitable Crops: Citrus, apple, mango, grape ⦁ Function: Enhances root vitality, improves fruit size, color, and sweetness. |
 | Vegetables ⦁ Suitable Crops: Tomato, cucumber, pepper, lettuce ⦁ Function: Promotes rapid growth, better leaf color, and higher yields. |
 | Field Crops ⦁ Suitable Crops: Corn, wheat, soybean ⦁ Function: Improves stress resistance, nutrient efficiency, and grain filling. |
 | Cash Crops ⦁ Suitable Crops: Tea, coffee, cotton, tobacco ⦁ Function: Boosts quality and output. |

FAQ
1. What is woody peat and why is it beneficial for soil?
Woody peat is an organic material formed from partially decomposed plant matter over long periods. It is rich in humic substances that improve soil structure, increase organic matter content, and enhance soil fertility.
2. How does humic acid improve soil quality?
Humic acid helps form soil aggregates, improving soil aeration, water retention, and nutrient availability. It also stimulates beneficial soil microbes that contribute to a healthier soil ecosystem.
3. Can this product replace traditional fertilizers?
This product provides both nutrients and soil conditioning benefits, but it is generally used together with a balanced fertilization program to achieve optimal crop performance.
4. Is it suitable for drip irrigation systems?
Yes. The product is 100% water-soluble and designed for use in drip irrigation, fertigation, and root irrigation systems without clogging equipment.
5. How long does it take to see results?
Improvements in plant vigor and root growth can often be observed within 1–2 weeks, while soil structure benefits become more noticeable with regular application over the growing season.
6. Can it help improve poor or compacted soils?
Yes. The humic substances and organic matter help loosen compacted soils, improve aeration, and restore soil biological activity over time.
