Key Product Features

High Purity & High Activity: Extracted from premium mineral humic sources, free of heavy metals and harmful impurities, with high biological activity for quick absorption by soil and crops
Excellent Solubility: Fully soluble in water with no insoluble residues, suitable for drip irrigation, sprinkler irrigation, foliar fertilization, and mixed applications
Stable Performance: Resistant to hard water, not prone to flocculation or precipitation, compatible with most acidic, neutral, and alkaline pesticides and fertilizers
Long-lasting Effect: Slowly releases nutrients in soil, improves soil buffering capacity, and provides sustained conditioning and fertilizing effects

Main Functions & Benefits

Soil Improvement

Optimize soil aggregate structure, loosen compacted soil, and reduce soil salinization and acidification damage
Enhance soil cation exchange capacity (CEC), improve water and fertilizer retention, and reduce nutrient leaching
Stimulate reproduction and activity of beneficial soil microorganisms, accelerating organic matter decomposition

Promote Crop Growth

Stimulate seed germination, increase germination rates and seedling survival, and promote robust root development
Accelerate crop metabolism, promote photosynthesis, and advance maturity periods for increased crop yields
Enhance crop stress resistance including drought, cold, disease, and lodging resistance

Improve Nutrient Utilization & Crop Quality

Chelate and activate medium and trace elements, converting ineffective nutrients into available forms
Improve fertilizer utilization rate by more than 30% through enhanced nutrient availability
Reduce nitrate accumulation in crops while increasing vitamin C, sugar, and protein content

Application Scope

Suitable for various soil types and all crops including field crops (wheat, corn, rice, soybean), cash crops (cotton, tobacco, tea), vegetables (tomato, cucumber, pepper), fruits (apple, grape, citrus, strawberry), flowers, nursery stocks, Chinese medicinal materials, ecological restoration, lawn maintenance, and soilless cultivation.

Application Methods

Soil Application: Mix with base fertilizer or topdressing, apply 15-30 kg per hectare via spreading, hole application, or furrow application
Drip & Sprinkler Irrigation: Dissolve 1-2 kg per mu in water, apply with irrigation water 2-3 times during crop growth period
Foliar Spraying: Dilute 800-1500 times with water, spray evenly on crop leaves 2-3 times at 7-10 day intervals
Seed Soaking & Root Dipping: Dilute 1000-1500 times with water, soak seeds for 8-12 hours or dip roots for 10-20 minutes before transplanting

Packaging & Storage

Packaging: 25kg kraft paper bag with inner plastic film bag, customizable packaging available
Storage: Store in cool, dry, ventilated place away from direct sunlight and moisture; keep separate from food, feed, and seeds
