Product Features & Advantages

Core Features

Organic & Natural: Sourced from high-quality organic matter, free of synthetic additives—aligns with global organic farming trends.
High Purity: Humic acid content ≥85%, ensuring potent efficacy compared to low-grade alternatives.
Soil Conditioning Expert: Improves soil structure, enhances water retention, and increases microbial activity for long-term soil health.
Bio-stimulant Effect: Acts as a bio-catalyst to promote plant growth, root development, and nutrient uptake (nitrogen, phosphorus, potassium).
Leaf Burn Reduction: When mixed with UAN (urea-ammonium nitrate) fertilizers, significantly reduces leaf burn—even at high application rates (15-35 gal/acre).
Versatile Compatibility: Works seamlessly with Natural Colorants, crop nutrients, and other agricultural inputs without compromising performance.

Our Competitive Edge

Unlike generic humic acid products, our bulk powder is produced via advanced extraction technology that preserves active ingredients. We strictly control the production process to avoid heavy metal contamination, and our product meets Food Additives safety standards—making it suitable for both agricultural and horticultural applications where purity is critical.

How to Use

Recommended Application Methods & Steps

Soil Application (Pre-Planting):
- Mix 50-100kg of humic acid powder per hectare with soil or organic fertilizer.
- Uniformly spread the mixture on the soil surface and till to a depth of 10-15cm.
- Water thoroughly to activate the product’s soil-conditioning properties.
Foliar Spray (Growing Period):
- Dilute 0.1-0.3% humic acid powder with water (1-3g per liter of water).
- Mix well and add to spray equipment; apply evenly on plant leaves (both sides) during early morning or late afternoon.
- Repeat every 7-10 days for optimal results (2-3 applications per growing cycle).
Drip Irrigation:
- Dilute 0.2-0.5% humic acid powder with irrigation water.
- Inject the solution into the drip system and run for 30-60 minutes to ensure uniform distribution.
- Apply every 15-20 days during the growing season.
Mixing with UAN Fertilizers:
- Add 10-30% humic acid powder to UAN (by volume) and stir thoroughly.
- Apply the mixture as a foliar spray or soil drench—leaf burn reduction increases with higher humic acid ratios.

Application Scenarios

Large-Scale Agriculture: Ideal for grains (wheat, corn, rice), cash crops (cotton, soybeans), and vegetables—improves yield by 10-20% and enhances crop quality.
Horticulture: Perfect for fruits (apples, oranges, grapes), flowers, and ornamental plants—promotes vibrant blooms and sweeter fruits, complementing Nutritional Supplements for plants.
Organic Farming: Complies with organic certification requirements, serving as a key input for farmers seeking to avoid synthetic chemicals.
Soil Remediation: Effective for degraded, saline-alkaline, or compacted soils—restores soil fertility and improves crop adaptability.
Hydroponics & Greenhouses: Enhances nutrient absorption in soilless cultivation systems, reducing fertilizer waste and lowering production costs.

Value for Buyers

Cost Savings: Reduces fertilizer usage by 15-20% (improves nutrient utilization) and lowers irrigation costs (enhances soil water retention).
Yield & Quality Boost: Increases crop yield by 10-25% and improves product quality (e.g., higher sugar content in fruits, better fiber quality in cotton).
Sustainability Compliance: Meets global organic and environmental standards, helping buyers cater to eco-conscious markets.
Versatility: Suitable for multiple crops and application methods, reducing the need for multiple specialized products.
Long-Term Soil Health: Builds soil organic matter over time, reducing the need for soil amendments and ensuring long-term agricultural productivity.

Frequently Asked Questions (FAQ)

Q: What is humic acid used for in agriculture?
A: Humic acid acts as a soil conditioner (improves structure and fertility) and bio-stimulant (promotes plant growth, nutrient uptake, and stress resistance). It also reduces leaf burn when mixed with UAN fertilizers.
Q: What color is your humic acid powder?
A: Our product is dark brown to black, which is the natural color of high-purity humic acid. The fulvic acid fraction (a component of our product) is soluble in water across all pH conditions.
Q: Can humic acid burn plants?
A: No—when used as directed, our humic acid powder is non-toxic and will not burn plants. In fact, it reduces leaf burn caused by UAN fertilizers, especially at 20-30% humic acid/UAN ratios.
Q: How long does it take to see results after application?
A: For soil conditioning, results (improved water retention, soil structure) are visible within 2-4 weeks. For plant growth promotion, you’ll notice enhanced root development and foliage growth within 1-2 growing cycles.
Q: Is your humic acid powder compatible with other agricultural inputs?
A: Yes—it works well with fertilizers, pesticides, Natural Colorants, and Plant Oil-based products. We recommend conducting a small compatibility test before large-scale application.
Q: What is the shelf life of the product?
A: 24 months when stored in a cool, dry, and sealed environment (away from direct sunlight and moisture).
