Humico (HumxPlus) Humic Acid Flakes is a kind of black shiny flake form humic acid with 2~4mm size. It’s manufactured for your flake organic fertilizer formula.
100% Water Solubility Flakes
Humico Humic Acid Flakes are complete, rapid water solubility and dissolve in any water temperature (cold, room, or warm) within seconds. Our Soluble humic acid flakes mixes evenly into water, so nutrients will be absorbed consistently by plants’ roots, leaves.
Humic Acid Flakes Manufacturing Process
HumxPlus Flakes (Humic acid flakes) are products refined from lignite via either a KOH or NaOH-based liquid-phase reaction. They exist as an alkaline form of active humic acid salt (humate).
Humico manufactures these soluble humic acid flakes using specialized machinery and through strict manufacturing processes. We strictly test all batches of products under the supervision of our vigilant and skilled staff.

Humic Acid Flakes Applications
Humico Humic Acid Flakes can be used for a wide range of agricultural and horticultural applications, designed to enhance plant growth, soil health, and overall productivity.
1. Soil Application
Base Fertilization: Incorporate 5-10 grams per square meter into the top 10-15 cm of soil before planting. This enriches soil structure, water-holding capacity, and cation exchange capacity (CEC) from the start.
Top Dressing: Sprinkle 3-5 grams per square meter around established plants during the growing season, then gently scratch into topsoil or water in for mid-season nutrient access.
Drip Irrigation: Add 0.5-1 kg per 1000 liters of water to irrigation reservoirs (ensure full dissolution). The solution delivers humic acid directly to root zones, ideal for large-scale fields.
2. Foliar Sprays
Preparation: Dissolve 0.5-1 gram of flakes in 1 liter of water (stir until fully clear).
Application: Use a fine-mist sprayer to coat leaves in early morning or late afternoon (when stomata are open). This boosts photosynthesis and provides quick stress resistance.
3. Seed Treatment
Seed Soaking: For 1 kg of seeds, soak in a solution of 50 grams of flakes + water for 1-2 hours before sowing. Accelerates germination and primes early root growth.
Seed Dressing: Mix 50 grams of flakes with 1 kg of seeds (shake gently to coat evenly). Protects seeds from soil pathogens and delivers slow-release nutrients.
4. Hydroponic & Aquaponic Systems
Add 50-100 grams of fully dissolved flakes to 100 liters of nutrient solution. Chelates nutrients for easier plant uptake and promotes healthy root development in soilless setups.
5. Suitable Plants
Vegetables
Leafy Greens: Spinach, lettuce, kale, and chard. Soil application or foliar sprays enhance leaf thickness, chlorophyll content, and resistance to yellowing.
Root Vegetables: Carrots, potatoes, beets, and radishes. Base fertilization improves soil looseness, reducing root splitting and boosting bulb/tuber size.
Fruiting Veggies: Tomatoes, peppers, cucumbers, and zucchini. Drip irrigation or top dressing enhances flower set, reduces blossom end rot, and improves fruit sweetness.
Fruits
Tree Fruits: Apples, oranges, mangoes, and peaches. Annual soil top dressing improves soil fertility, leading to larger fruit size and more consistent ripening.
Berry Bushes: Strawberries, blueberries, raspberries, and blackberries. Foliar sprays during flowering boost berry yield, while seed soaking (for new plants) accelerates establishment.
Vines: Grapes and kiwis. Hydroponic/aquaponic addition or soil drip application enhances vine vigor and berry sugar content.
Grains & Cereals
Major Crops: Wheat, maize (corn), rice, and soybeans. Large-scale drip irrigation ensures uniform nutrient access, increasing stalk strength and reducing lodging (falling over) in windy conditions.
Small Grains: Oats, barley, and rye. Seed soaking improves germination rates in cool soils, ensuring earlier, more even crop stands.
Ornamentals & Flowers
Flowering Shrubs: Roses, hydrangeas, and lilacs. Soil top dressing enhances bloom vibrancy and extends flowering periods, while foliar sprays reduce leaf browning.
Potted Plants: Geraniums, petunias, and succulents. Diluted foliar sprays (0.3-0.5 grams per liter) prevent nutrient deficiencies in container soil, keeping foliage lush.
Cut Flowers: Chrysanthemums, carnations, and sunflowers. Seed treatment or early soil application strengthens stems, prolonging vase life after cutting.
Herbs
Culinary Herbs: Basil, mint, rosemary, and thyme. Foliar sprays enhance aromatic oil production (boosting flavor) and prevent wilting in dry conditions.
Medicinal Herbs: Lavender, echinacea, and chamomile. Soil application improves root health, ensuring plants accumulate key beneficial compounds.
Lawns & Turf
Apply 2-3 grams per square meter via top dressing or diluted spray (1 gram per liter) during spring and fall. Enhances grass root depth, drought resistance, and recovery from foot traffic or mowing stress.
