Sourced from premium Leonardite—one of the richest natural sources of fulvic acid—this product undergoes a state-of-the-art extraction and refinement process that preserves the full spectrum of bioactive compounds while enhancing its solubility to an exceptional degree. Unlike traditional potassium fulvate products that may clump or dissolve slowly, our instant powder achieves complete dissolution in water within seconds, even at room temperature, eliminating the need for prolonged stirring or special equipment.
1. Soil Health Revitalization: increased soil fertility, reduced soil erosion, and a more balanced soil pH, particularly in acidic or saline-alkali soils.
2. Enhanced Nutrient Uptake & Utilization: It binds to essential nutrients (including nitrogen, phosphorus, potassium, and micronutrients) in the soil, converting them into stable, water-soluble complexes that are not easily lost to leaching or volatilization.
3. Crop Stress Resistance & Quality Improvement: The bioactive fulvic acid in the instant powder enhances crops' natural defense mechanisms against environmental stressors.It also elevates crop quality: for fruits and vegetables, it increases sugar content, improves coloration, and extends shelf life.

1. Staple Crops: Ideal for rice, wheat, corn, cotton, and soybeans. Applied as a foliar spray or soil drench during key growth stages (such as seedling, tillering, and flowering), it boosts yield by 10-15% and improves crop resistance to adverse weather conditions like drought or floods.
2. Oilseeds & Pulses: Effective for crops like rapeseed, sunflower, and lentils. It enhances seed oil content and improves pod setting, leading to higher-quality harvests.
3. Fruit Crops: Perfect for apples, oranges, grapes, strawberries, and mangoes. When applied during fruit expansion and ripening stages, it enhances fruit sweetness, improves skin texture, and reduces the incidence of physiological disorders like bitter pit in apples.
4. Vegetable Crops: Suitable for tomatoes, cucumbers, peppers, lettuce, and carrots. It promotes uniform growth, increases fruit yield, and enhances the nutritional value (e.g., higher vitamin C content) of vegetables.
1. Foliar Spray (Most Common Method)
(1)Dosage: Dilute the powder with clean water at a ratio of 1:1000-1500 (i.e., 1 kilogram of powder mixed with 1000-1500 liters of water). For sensitive crops (such as seedlings or delicate flowers), use a higher dilution ratio (1:1500-2000) to avoid leaf burn.
(2)Application Timing: Apply during the early morning (before 10 a.m.) or late afternoon (after 4 p.m.) when temperatures are lower and sunlight is less intense. This prevents the solution from evaporating too quickly and ensures maximum absorption by the leaves.
(3)Method: Use a sprayer with a fine nozzle to apply the diluted solution evenly to both the upper and lower surfaces of the leaves. For large-scale farms, use a tractor-mounted sprayer for efficient coverage. Repeat the application every 7-10 days during the crop's active growth stages (e.g., seedling, flowering, and fruit development).
2. Soil Drench/Irrigation
(1)Dosage: For soil drenching, use a dilution ratio of 1:800-1200 (1 kilogram of powder per 800-1200 liters of water). For drip irrigation systems, add 0.5-1 kilogram of powder per hectare per application.
(2)Application Timing: Apply during the early stages of crop growth (e.g., after sowing or transplanting) to establish a healthy root system, and again during nutrient-demanding stages (e.g., fruit expansion).
(3)Method:
Soil Drench: Pour the diluted solution directly around the root zone of the crop, ensuring the soil is thoroughly moistened.
Drip Irrigation: Dissolve the powder in a water tank, then connect the tank to the drip irrigation system. Run the system for 30-60 minutes to ensure the solution is evenly distributed throughout the root zone. This method is highly efficient and reduces water and nutrient waste.
3. Seed Treatment
(1)Dosage: Dilute the powder with water at a ratio of 1:500-600 (1 kilogram of powder per 500-600 liters of water).
(2)Method: Soak the seeds in the diluted solution for 6-12 hours (depending on the seed type: e.g., rice seeds soak for 8-12 hours, vegetable seeds soak for 6-8 hours). After soaking, remove the seeds, dry them to a slightly moist state, and sow immediately. This treatment improves seed germination rate by 10-15%, enhances seedling vigor, and reduces the risk of seed-borne diseases.
4. Mixing with Fertilizers/Pesticides
(1)Dosage: Mix 0.5-1 kilogram of Potassium Fulvate Instant Powder with 50-100 kilograms of chemical fertilizer (e.g., urea, compound fertilizer) or organic fertilizer (e.g., manure, compost). When mixing with pesticides, use a dilution ratio of 1:1000-1200 and ensure compatibility by conducting a small-scale test first.
(2)Method: Mix the powder with the fertilizer or pesticide thoroughly before application. This not only improves the effectiveness of the fertilizer/pesticide but also reduces their potential negative impact on the soil and crops.
