Premium 100% Water Soluble Potassium Fulvate Organic Fertilizer with 50% Fulvic Acid for Soil Improvement

Our premium mineral-source potassium fulvate is a high-activity organic plant stimulant and professional soil conditioner refined from high-purity leonardite. Unlike common biochemical fulvic acid, this mineral-based formula features small molecular weight, ultra-high biological activity, and full water solubility, making it one of the most efficient and versatile organic fertilizer additives for modern agricultural planting.

It can be used alone or mixed with conventional chemical fertilizers, pesticides, and water-soluble fertilizers to significantly boost nutrient utilization efficiency, improve soil health, and promote high-quality crop growth.

Specially designed for global commercial farms, greenhouse planting, and cash crop cultivation, our potassium fulvate solves core planting challenges including hardened soil, nutrient loss, poor root development, low stress resistance, and inferior crop quality, providing a safe, efficient, and eco-friendly nutrition solution for sustainable agriculture.

Extracted from natural high-grade leonardite, the product contains fulvic acid ≥50%, humic acid ≥50%, and potassium oxide (K₂O) ≥12%, with stable and reliable active ingredient content. Free of chemical additives, heavy metals, and harmful residues, it meets international organic agricultural planting standards and is safe for all crops and soil environments.

Adopts superfine powder processing technology with uniform particle size, achieving instant dissolution in water without precipitation or stratification. It adapts to various water quality including hard water, perfectly matching fertigation, drip irrigation, sprinkler irrigation, and foliar spray systems. No blockage of irrigation equipment, fully compatible with all modern agricultural irrigation facilities.

As a powerful soil conditioner, it effectively loosens hardened soil, regulates soil pH balance, improves saline-alkali land, and enhances soil water and fertilizer retention capacity. It activates soil beneficial microorganisms, decomposes fixed soil nutrients, and fundamentally improves soil ecological environment. For crops, it stimulates root germination, increases root hair quantity, accelerates nutrient absorption, and promotes robust seedling growth.

Significantly improve crop resistance to drought, cold, high temperature, lodging, and continuous cropping obstacles. It alleviates crop damage caused by flood, saline-alkali stress and heavy metal pollution, reduces the incidence of physiological diseases, and improves crop survival rate in harsh growth environments.

It chelates nitrogen, phosphorus, potassium and trace elements in soil and fertilizers, preventing nutrient fixation and loss. It can improve chemical fertilizer utilization rate by 30%-50%, effectively reducing the dosage of traditional fertilizers and pesticide usage, cutting overall agricultural input costs while achieving green planting.

Promote crop flower bud differentiation, reduce flower and fruit drop, accelerate fruit expansion, coloring and sugar accumulation. It effectively improves crop taste, appearance and commodity value, and increases crop yield by 10%-25% in normal planting conditions, bringing higher economic benefits for growers.

Widely suitable for all types of crops, universally applicable for global agricultural planting:

• Fruit Trees: Apple, grape, citrus, banana, mango, strawberry, watermelon, etc.
• Vegetables: Tomato, cucumber, pepper, eggplant, cabbage, leafy vegetables, etc.
• Field Crops: Rice, wheat, corn, cotton, soybean, peanut, tobacco, etc.
• Economic Crops & Flowers: Tea, coffee, medicinal herbs, various ornamental flowers and seedlings

Our potassium fulvate supports multiple application methods, flexible and convenient for different planting scenarios:

Dilute 10-15g of product with 10L water, spray evenly on leaf surfaces, 2-3 times per growth cycle with 7-10 days interval. It rapidly supplements nutrients, enhances photosynthesis, and improves crop stress resistance.

Apply 2-3kg per hectare each time, dissolve completely and add to irrigation system. It improves soil activity, promotes root growth, and improves fertilizer utilization efficiency.

Mix 3-5kg per hectare with base fertilizer and apply to soil, effectively improve soil structure and lay a solid foundation for crop growth.

Dilute 1:800-1000 with water, soak seeds for 4-6 hours or dip seedling roots for 10-15 minutes to improve seed germination rate and seedling survival rate.

Mineral-source potassium fulvate is extracted from natural leonardite with stable molecular structure, high activity and strong soil improvement ability. Biochemical fulvic acid is fermented from plant residues with low activity and single effect. Our mineral-based product has better comprehensive effects on soil repair, root promotion and stress resistance.

Yes, it can be mixed with most neutral and acidic water-soluble fertilizers, macro and trace element fertilizers, and pesticides. It can improve fertilizer and pesticide efficacy, reduce  residue, and save planting costs. Avoid mixing with strong alkaline pesticides.

Absolutely. The weak alkaline formula can neutralize soil acid-base imbalance, decompose soil salt components, improve saline-alkali soil hardening, and create a breathable and fertile soil environment for crop root growth.
