Potassium humate flake

Potassium Humate Flakes are a highly concentrated, water-soluble humic fertilizer produced from selected natural humic materials. The product contains humic acid and potassium in a convenient black flake form, allowing it to dissolve quickly in water and be used in a wide range of agricultural fertilization systems. Potassium Humate helps improve soil structure, increase nutrient availability, promote root development, and support healthy crop growth. It can enhance the utilization efficiency of nitrogen, phosphorus, potassium, and trace elements while helping reduce nutrient loss from the root zone. The product is suitable for field crops, vegetables, fruit trees, flowers, greenhouse plants, lawns, nurseries, and other commercial crops. It can be applied through fertigation, drip irrigation, soil application, root irrigation, fertilizer blending, and foliar nutrition programs according to local crop and soil requirements.

Benefits

Key Product Benefits

Improves soil structure by helping loosen compacted soil, increasing soil porosity, and creating a healthier root-zone environment for long-term crop development.

Promotes stronger and more extensive root growth, allowing plants to absorb water and essential nutrients more efficiently during different growth stages.

Enhances the utilization efficiency of nitrogen, phosphorus, potassium, and trace elements while helping reduce nutrient loss and unnecessary fertilizer waste.

Improves soil water-holding capacity and moisture retention, helping crops maintain more stable growth under dry conditions or irregular irrigation schedules.

Supports beneficial soil microbial activity, improves soil vitality, and helps maintain a more balanced and productive environment around the plant roots.

Helps crops better tolerate drought, salinity, transplanting stress, temperature fluctuations, and other unfavorable conditions while supporting crop quality and uniformity.

Applications

Where & How to Use

Potassium Humate Flakes are widely used in agriculture, horticulture, greenhouse cultivation, landscaping, soil improvement, and commercial fertilizer production. The product is suitable for cereals, vegetables, fruit trees, flowers, tea, coffee, cotton, oil crops, lawns, nursery plants, and many other agricultural and horticultural crops. It can be applied through drip irrigation, sprinkler irrigation, fertigation systems, soil application, root irrigation, seed treatment, fertilizer blending, and foliar nutrition programs. The product may be dissolved in water before application or incorporated into compatible compound fertilizers, NPK fertilizers, water-soluble fertilizers, and micronutrient formulations. When applied to soil, Potassium Humate helps improve soil aggregation, aeration, water retention, and nutrient-holding capacity. It also supports beneficial microbial activity and helps create a healthier environment for root development. During crop growth, it promotes nutrient absorption, strengthens plant development, and supports better adaptation to drought, salinity, transplanting stress, and other unfavorable conditions. Potassium Humate Flakes can be used during seedling establishment, vegetative growth, flowering, fruit setting, fruit development, and crop recovery stages. The appropriate application rate should be adjusted according to crop type, soil conditions, irrigation method, local climate, and professional agronomic recommendations.
