Import Bio Potassium Fulvate , Potassium Fulvic Acid — Buy in wholesale FOB from Supplier in China

Potassium fulvate is an organic potassium fertilizer derived from humic substances, specifically combining humic acid and fulvic acid fractions to enhance potassium availability in soil. The active fulvic acid and humic acid components chelate soil minerals and improve cation exchange capacity, which the supplier notes can reduce potassium fixation and increase plant uptake. When blended with urea, the product allows a one-third reduction in urea dosage while extending nitrogen release by 40 to 50 days, a characteristic of slow-release formulations. The supplier states fertilizer utilization improves by 87% to 95% compared with conventional potash sources, though buyers should verify these figures against independent trials for their specific crop and soil conditions.

The material is typically produced through alkaline extraction from leonardite or brown coal sources, followed by potassium hydroxide neutralization to create the water-soluble potassium salt of fulvic acid. Standard commercial grades contain 5% to 15% potassium oxide (K2O) equivalent, with fulvic acid content ranging from 40% to 70% by weight depending on source material and extraction method. The dark brown to black powder or flake form dissolves readily in water, making it compatible with drip irrigation and foliar application systems. pH typically falls between 8 and 11 for potassium fulvate products, reflecting their alkaline nature. The supplier indicates compatibility with urea, NPK compounds, trace elements, and diammonium phosphate (DAP), though jar testing is advisable before tank-mixing with novel combinations.

Primary buyers include compound fertilizer manufacturers seeking organic-certified additives, large-scale agricultural operations in potassium-deficient soils, and specialty crop producers targeting premium organic markets. The product suits integration into fertigation programs for fruits, vegetables, and high-value field crops where potassium efficiency directly affects yield and quality parameters such as sugar content, oil percentage, and storage life. Shandong Province, where the supplier is located, is a major Chinese hub for humate and fulvate production due to proximity to coal-derived raw material deposits. Buyers should confirm minimum order quantities, packaging specifications, and whether the supplier provides third-party laboratory analysis for humic acid fraction composition and heavy metal limits before committing to shipment.

Zhongchuang Xingyuan Chemical Technology Co., Ltd. is headquartered in Taian, Shandong Province, China, with postal address listed at 271000. The company operates under the Harbor trust tier classification, with a response rate currently showing 0.00% and zero recorded average response hours. This indicates the supplier profile may be newly established, minimally staffed for international inquiry management, or experiencing data tracking issues. Buyers should initiate contact through multiple channels and document response times before relying on this supplier for time-sensitive orders.

The listing provides no verified information about factory size, annual output, export license status, quality management certification, or years in operation. No specific client references, domestic market share, or R&D capabilities are mentioned. The supplier's product focus appears to be on organic potassium fertilizers and compound fertilizer additives rather than broad chemical manufacturing. Given the absence of response data, prospective buyers should request a current business license, product test reports for heavy metals and humic acid content, and sample material for their own agronomic trials before negotiating commercial terms.
