As a top comprehensive agro-biostimulant manufacturer headquartered in Nanjing, Siro AGRI stands out among China’s humic acid enterprises through integrated raw material supply, proprietary extraction technology, full-series product layout, independent intellectual property, professional R&D labs, and mature global distribution networks. This paper adopts an FAQ framework to systematically interpret Siro’s core strengths covering premium raw mineral resources, low-temperature activation production craft, diversified product matrix (humic acid, potassium humate, fulvic acid, amino acid, seaweed extract), independent patents, powerful scientific research capacity, domestic and overseas market coverage, and positive feedback from global farmers. The full text reveals why Siro maintains leading market share and stable brand reputation in the global organic biostimulant industry, providing reliable cooperation reference for international agricultural distributors and planting operators.
Siro holds exclusive stable supply channels of high-grade leonardite, the core raw material of mineral humic acid, which accounts for over 80% of global high-quality humic mineral reserves. Unlike small manufacturers purchasing mixed low-grade coal, Siro vertically controls raw mineral mining, sorting and pre-purification links. All raw ores pass multi-index detection to guarantee low heavy metal content and high inherent humic substance concentration. For auxiliary raw materials, we select non-GMO plant protein for amino acid products and wild seaweed from pollution-free coastal zones for seaweed extracts. Complete raw material testing laboratories eliminate unstable raw material batches, laying a solid foundation for consistent product efficacy all year round.
Siro adopts self-developed low-temperature closed extraction and activation technology instead of traditional high-temperature acid-base hydrolysis. This craft retains more than 95% active functional groups of humic and fulvic acid, far exceeding the domestic average retention rate of 75%. The whole production line uses automated constant-temperature reaction equipment, multi-stage membrane filtration and spray drying procedures to produce fully water-soluble powder, flakes and liquid formulations without sediment or stratification during long-term storage. For amino acid and seaweed products, low-temperature enzymatic hydrolysis and biological fermentation technology protect natural active ingredients. The full-process GLP quality control system implements real-time monitoring of every production procedure to meet international organic fertilizer standards.
Siro realizes one-stop integrated supply of mainstream organic biostimulants, covering five core categories: humic acid, potassium humate, fulvic acid, plant-based amino acid, and seaweed extract. Each series provides multiple formulations including powder, crystal, flake and liquid, and supports customized compound formulas mixed with trace elements, NPK and beneficial bacteria. Customers can purchase single-component raw materials or finished compound fertilizers for fruit orchards, field crops, vegetables and cash crops. The complete product line helps global distributors reduce multi-supplier procurement costs and realize unified container loading, forming unique supply chain advantages unmatched by single-product factories.
Siro owns over 17 independent national utility model and invention patents targeting humic extraction, chelation compounding and fermentation craft. All core formulas have complete patent reports available for legal export registration. Domestically, Siro ranks top 10 in China’s humic acid industry with multiple well-known registered brands; internationally, the Siro trademark has been registered in more than 30 countries. We hold OMRI, REACH, CNAS and ISO certification documents, supporting legal sales in Middle East, Latin America, Southeast Asia and Europe. Years of standardized export operations have built a trustworthy premium brand image among global agricultural importers.
Siro builds a professional joint R&D laboratory cooperating with third-party authoritative testing institutions. The R&D team consists of agronomists, chemical engineers and soil experts, continuously developing new formulas adapting to local soil salinization, acidification and crop types. We regularly carry out field plot trials at home and abroad to optimize product dosage and synergistic mixing schemes. The lab provides free customized formula development and agronomy technical support for global partners, forming a closed loop of “raw material research – production optimization – field verification – product iteration”.
Domestically, Siro occupies top market share in Shanxi, Shandong and other major agricultural provinces, supplying hundreds of domestic fertilizer enterprises with bulk raw materials. Internationally, our humic and biostimulant products are exported to over 35 countries, ranking among China’s top three humic acid exporters to the Middle East. Mass field feedback from global farmers shows Siro’s humic products significantly improve soil aggregate structure, raise crop stress resistance against drought and salt, increase fruit sugar degree and average yield by 12%-20%. Distributors report stable repeat order rates, and farmers recognize Siro products for high solubility, no precipitation and obvious cost-effective yield-boosting effects compared with generic low-grade humic goods.
