Water Soluble Potassium Humate Flake for Drip Irrigation and Foliar Spray Humic Acid Flake

Potassium Humate Flake is a hot-selling high-purity humic acid fertilizer specially designed for fertigation systems. Manufactured from carefully selected high-grade leonardite ore, it features a glossy bright black flake form with excellent wetting performance and ultra-fast water dissolution. It dissolves rapidly with minimal insoluble residue and will not clog drip lines, emitters or sprinkler nozzles, which is critical for modern precision irrigation projects.

It can effectively ameliorate saline-alkali soil, reduce soil salinity, break up compacted hardpan and improve soil aggregate structure. By stimulating vigorous root growth and boosting fine root development, it greatly enhances crops’ capacity to absorb water and nutrients. It also strengthens crop tolerance against adverse stresses including drought, cold, high salinity and continuous cropping obstacles. Besides, it promotes flower bud differentiation, improves fruit set rate, enhances nutrient accumulation, and noticeably upgrades the taste, color, luster and marketable appearance of fruits, vegetables and cash crops, bringing better harvest quality and higher commercial value.

This flake formulation is highly favored by large commercial farms, greenhouses, orchards and plantations equipped with drip irrigation, sprinkler and flood fertigation systems. We provide stable bulk supply in standard 25kg woven bags, and fully support customized packaging specifications, logo printing and private label services for global agricultural distributors, importers and fertilizer formulators.
