Market Overview
The global humic acid market was valued at USD 2,687.6 Million in 2025 and is projected to reach USD 4,832.4 Million by 2032, registering a CAGR of 8.73% during 2026–2032. In absolute terms, the market is expected to add USD 2,144.8 Million between 2025 and 2032. Historically, the market expanded from USD 2,081.8 Million in 2022 to USD 2,468.9 Million in 2024, reflecting steady adoption of humic substances as soil conditioners, fertilizer efficiency enhancers and plant biostimulants across both broad-acre and high-value cropping systems.
Demand is underpinned by the deterioration of soil organic matter in intensively farmed land, sustained pressure to raise the efficiency of mineral fertilizers following the 2021–2022 fertilizer price shock, and the formal recognition of biostimulants in fertilizer legislation in the European Union and India. Humic acid products, derived principally from leonardite, lignite, humalite and peat, are increasingly positioned as functional inputs that improve cation exchange capacity, nutrient availability and water-holding capacity rather than as commodity soil amendments.
Key Findings
Physical Form: Granular products accounted for the largest share at 40.0% (USD 1,075.0 Million) in 2025, while Liquid formulations are the fastest-growing form with a CAGR of 9.53% during 2026–2032.
Crop Type: Cereals & Grains and Fruits & Vegetables each held 35.0% of the market in 2025 (USD 940.7 Million each). Fruits & Vegetables is the fastest-growing crop segment with a CAGR of 9.31%.
Application Method: Soil application dominated with 70.0% share (USD 1,881.3 Million) in 2025, whereas Foliar application is projected to grow fastest at a CAGR of 9.53%.
Region: Asia Pacific was the leading region in 2025 with a 33.0% share (USD 886.9 Million). Middle East & Africa is the fastest-growing region with a CAGR of 9.52%, closely followed by Asia Pacific at 9.39%.

Segmentation Summary
By physical form, the market is segmented into Granular, Liquid and Powder. Granular humates remain the preferred format for broad-acre soil application because they can be blended with dry fertilizers and spread with existing equipment, which explains their 40.0% share. Liquid products, which accounted for 35.0% of 2025 revenue, are gaining share on the back of fertigation, drip irrigation and tank-mix compatibility with foliar nutrition programmes. Powder products (25.0%) consist mainly of water-soluble potassium and sodium humates used by fertilizer formulators and in regions where the cost of freight per unit of active ingredient is a key purchase criterion.
By crop type, Cereals & Grains and Fruits & Vegetables together represented 70.0% of the market in 2025, with the remaining 30.0% attributed to Others, which covers oilseeds and pulses, cash and plantation crops, turf and ornamentals. By application method, soil application accounted for 70.0% of demand, reflecting the primary role of humic acid as a soil conditioner, while foliar application (30.0%) is expanding faster as growers adopt biostimulant spray programmes in horticulture.
Competitive Landscape Summary
The global humic acid market is moderately fragmented. A group of specialised producers with access to their own humate deposits or long-standing extraction know-how, such as Humintech GmbH, HGS BioScience, Huma, Inc., Black Earth (WestMET Group) and Live Earth Products, competes alongside diversified agricultural input groups including Rovensa (through Tradecorp and Rovensa Next), Omnia Holdings and The Andersons, Inc. In China, a large base of domestic manufacturers such as Shandong Nongda Fertilizer Technology and Shandong Chuangxin Humic Acid Technology supplies both the domestic market and export channels. Competitive activity since 2022 has been characterised by acquisitions and vertical integration into humate mining, rebranding around broader biostimulant platforms, and capacity investments in extraction and granulation.
Challenges and Opportunities
The principal challenges facing the market are inconsistent product quality and labelling of humic acid content, the variability of agronomic response under different soil and climatic conditions, and the fragmented regulatory treatment of biostimulants across countries, which raises registration costs for multinational suppliers. Farmers' price sensitivity in commodity crops and competition from alternative biostimulants such as seaweed extracts, protein hydrolysates and microbial products also constrain pricing.
Opportunities exist in humic-enhanced fertilizers (coated urea, compound and water-soluble fertilizers), combination products that pair humic substances with microbial inoculants, reclamation of saline and degraded soils, and the expansion of regenerative and organic farming programmes. Emerging agricultural economies in Asia Pacific, Latin America and the Middle East & Africa offer the highest growth potential, with each of these three regions expected to grow faster than the global average.
Future Outlook
Over the forecast period, the market is expected to almost double from USD 2,687.6 Million in 2025 to USD 4,832.4 Million in 2032. Growth will increasingly be driven by liquid and foliar formats, high-value fruit and vegetable production and emerging economies, while Asia Pacific will continue to be the largest regional market, expanding from USD 886.9 Million in 2025 to USD 1,667.2 Million in 2032. Suppliers that can demonstrate consistent humic acid content, provide field-trial evidence and secure registrations under the evolving biostimulant regulations are expected to gain share.
The Humic Acid Market market is projected to grow at a CAGR of 8.8% from 2022 to 2032.

View Subscription PlansDefinition
Humic acid is the fraction of humic substances, the dark-coloured, high-molecular-weight organic compounds formed through the decomposition and humification of plant and microbial residues, that is soluble in alkaline solution and precipitates when the solution is acidified to a pH below 2. It is distinguished from fulvic acid, which is soluble at all pH values, and from humin, which is insoluble at any pH. Chemically, humic acids are heterogeneous supramolecular associations rich in carboxylic and phenolic functional groups, which give them a high cation exchange capacity and the ability to complex metal ions and micronutrients.
Commercial humic acid is extracted mainly from leonardite (oxidised lignite), lignite and brown coal, humalite and peat by alkaline extraction, typically with potassium or sodium hydroxide, followed by separation, concentration and drying or granulation. In agriculture, humic acid products are applied to improve soil structure, water retention and nutrient availability, to increase the efficiency of mineral fertilizers and to stimulate root growth.
Included in the scope: humic acid and humate products used in crop production, including leonardite- and humalite-based humate granules, liquid humic acid concentrates, water-soluble potassium and sodium humate powders and flakes, and humic acid products marketed as soil conditioners, fertilizer additives or plant biostimulants, in which humic acid is the principal active component.
Excluded from the scope: non-agricultural uses of humic substances such as animal feed additives, drilling fluids, industrial binders, water treatment and pharmaceutical or cosmetic applications; raw or unprocessed peat, compost and manure sold as bulk organic matter; and stand-alone fulvic acid products.

Analytical insights on Humic Acid Market covering market dynamics, competitive landscape, and strategic outlook.
The Humic Acid Market market is projected to reach $4.83B by 2032, growing at 8.8% CAGR. The Granular segment holds the largest share.
The global humic acid market, valued at USD 2,687.6 Million in 2025, is shaped by the interaction of agronomic, economic and regulatory forces. On the demand side, the decline of soil organic matter, the economics of mineral fertilizers and the rapid development of the plant biostimulant category are the most important influences. On the supply side, access to high-quality humate deposits, extraction technology and the ability to register products under evolving biostimulant rules determine competitiveness.
This chapter presents a growth factor analysis followed by the main drivers, restraints, opportunities, trends and challenges. The impact scores in the growth factor analysis are analyst assessments, based on secondary research and industry discussions, of the relative strength of each factor on market growth over three time horizons, on a scale of 1 (minimal impact) to 10 (very strong impact).
Deteriorating Soil Health and Policy Focus on Soil Organic Matter
Decades of intensive tillage, monocropping and reliance on mineral fertilizers have depleted soil organic carbon in many agricultural regions. The Food and Agriculture Organization's assessment of the status of the world's soil resources found that around one-third of the world's soils are moderately to highly degraded through erosion, nutrient depletion, acidification, salinisation and compaction. Soils low in organic matter have lower cation exchange capacity, weaker aggregate stability and lower water-holding capacity, which directly reduces fertilizer response and yield stability.
Policy attention to soil health has increased markedly. In the European Union, Directive (EU) 2025/2360 on soil monitoring and resilience establishes the first EU-wide framework for monitoring soil health. In the United States, the USDA Natural Resources Conservation Service promotes soil health practices through technical and financial assistance programmes, and India's Soil Health Card scheme provides farmers with soil test-based nutrient recommendations. Because humic acid improves soil structure, nutrient retention and microbial activity, it is increasingly recommended as part of soil restoration programmes, creating sustained demand for granular and powder humates applied to soil.
Need for Higher Fertilizer Use Efficiency
The sharp rise in nitrogen, phosphate and potash prices in 2021–2022, driven by high natural gas prices, export restrictions and the conflict in Ukraine, exposed growers to the cost of inefficient nutrient use. Although prices have since moderated from their peaks, fertilizer remains one of the largest variable costs in crop production, and a substantial share of applied nitrogen and phosphorus is not taken up by crops. Humic acids complex micronutrients, reduce phosphate fixation in calcareous and acidic soils and help retain nutrients in the root zone, which positions them as fertilizer efficiency enhancers.
Policy objectives reinforce this trend. The European Commission's Farm to Fork Strategy aims to reduce nutrient losses by at least 50% and fertilizer use by at least 20% by 2030, while China has pursued fertilizer-use reduction since its 2015 action plan for zero growth in fertilizer use. Fertilizer manufacturers are responding by incorporating humic acid into compound fertilizers, coated urea and water-soluble fertilizers, as illustrated by large Chinese producers that market humic acid-enhanced fertilizers. This integration of humic acid into mainstream fertilizer products significantly expands the addressable market beyond stand-alone soil conditioners.
Formalisation of the Plant Biostimulant Category
Humic substances are one of the main categories of plant biostimulants, alongside seaweed extracts, protein hydrolysates and microbial products. Regulatory recognition of biostimulants has improved market access and buyer confidence. Regulation (EU) 2019/1009 on EU fertilising products, applicable since July 2022, created a harmonised CE-marking route for plant biostimulants and soil improvers across the EU single market. In India, biostimulants were brought under the Fertiliser (Control) Order, 1985 in 2021, with humic and fulvic acids recognised as a distinct category in the biostimulant schedule, and provisional registrations were phased out in 2025 in favour of full registration.
In the United States, the Environmental Protection Agency has issued guidance on plant regulator claims, including for plant biostimulants, clarifying when label claims bring a product under pesticide regulation, and federal legislation to define plant biostimulants has been proposed in Congress. Clearer rules favour suppliers with consistent product quality and agronomic data, encourage investment from large agricultural input companies and support the inclusion of humic products in mainstream crop nutrition programmes.
Expansion of High-Value Horticulture, Fertigation and Protected Cultivation
Global production of fruits and vegetables continues to expand, supported by rising incomes, dietary diversification and export-oriented horticulture in countries such as Mexico, Spain, Italy, Morocco, India and China. These crops have high input intensity and value per hectare, which makes growers more willing to invest in biostimulants that improve root development, nutrient uptake and quality parameters. The adoption of drip irrigation, fertigation and greenhouse production allows humic acid to be applied in liquid form through irrigation systems at precise timings.
As a result, liquid humic acid formulations and foliar programmes are expanding faster than the market as a whole. Water scarcity in Mediterranean, Middle Eastern and South Asian agriculture is accelerating the shift to micro-irrigation, which in turn favours soluble humates. This driver underpins the above-average growth of the Fruits & Vegetables, Liquid and Foliar segments over 2026–2032.
Humic-Enhanced Fertilizers and Combination Products
The integration of humic acid into urea, compound NPK and water-soluble fertilizers offers a large-volume opportunity, as it allows suppliers to reach growers through existing fertilizer distribution. Combination products that pair humic substances with microbial inoculants, seaweed extracts or micronutrients are also gaining traction, as humic acid can act as a carrier and growth substrate for beneficial microorganisms. Acquisitions by specialists such as HGS BioScience and Huma, Inc. into adjacent biostimulant and fertilizer businesses reflect this convergence.
Reclamation of Saline, Sodic and Degraded Soils
Large areas of irrigated land in China, India, Pakistan, the Middle East, North Africa and Australia are affected by salinity and sodicity. Humic acid improves soil aggregation, enhances calcium availability and mitigates the effects of sodium on root growth, making it a component of soil reclamation programmes. Government-supported land rehabilitation initiatives and the expansion of agriculture into marginal land create demand for granular and powder humates applied at higher rates per hectare.
Regenerative Agriculture, Organic Farming and Carbon Programmes
Food and beverage companies are increasingly sourcing from regenerative agriculture programmes that reward practices improving soil health. Organic farmland worldwide is close to 100 million hectares according to surveys by FiBL and IFOAM – Organics International, and naturally derived humic acids are permitted in organic production in the United States under the USDA National Organic Program. These trends support premium positioning for certified, naturally sourced humic acid products and open new channels through sustainability-linked procurement programmes.
Variability in Product Quality and Lack of Uniform Labelling
Humic acid products vary considerably in raw material source, extraction method and actual humic acid content. Historically, different analytical methods have produced widely different results for the same product, enabling inflated label claims and making it difficult for growers to compare products. Although ISO 19822:2018 provides a standardised method for determining humic and hydrophobic fulvic acid concentrations in fertilizer materials, its use is not mandatory in many markets. Low-quality and diluted products undermine farmer confidence and create price pressure on reputable suppliers.
Inconsistent Agronomic Response and Limited Awareness
The effect of humic acid on yield depends on soil type, organic matter level, crop, climate and the quality of the product applied. Benefits are often more visible in degraded, sandy or calcareous soils than in fertile soils, and responses in commodity crops may be modest relative to their cost. In many developing markets, smallholder farmers have limited access to agronomic advice and field-trial evidence, which slows adoption and keeps demand concentrated in commercial and export-oriented farming.
Regulatory Fragmentation and Registration Costs
Despite progress, biostimulant regulation remains fragmented. In the United States, fertilizer and soil amendment products are registered at the state level, and requirements differ between states. Registration in India, Brazil and China requires local data and dossiers, while the EU's CE-marking route requires conformity assessment. These requirements increase time to market and cost for smaller suppliers and can delay the launch of new formulations.
Shift Towards Liquid and Water-Soluble Formats
Growers are moving from bulk granular products towards liquid concentrates and water-soluble powders that can be applied through fertigation systems or tank-mixed with crop protection and foliar nutrition products. Suppliers are investing in extraction, concentration and spray-drying capacity, as demonstrated by HGS BioScience's research and pilot facility for humic and fulvic extraction, spray drying and granulation opened in Mississippi in 2023.
Consolidation and Vertical Integration into Humate Mining
The market is consolidating as specialists and private-equity-backed platforms acquire mining assets and complementary product lines. WestMET Group's acquisition of Black Earth in December 2024, HGS BioScience's acquisition of Earthgreen Products and Menefee Mining in 2025, and Huma, Inc.'s acquisition of Gro-Power in 2024 illustrate the trend towards integration from deposit to finished product, which provides control over raw material quality and cost.
Growing Demand for Agronomic Evidence
Regulators, distributors and growers increasingly expect verified claims supported by field trials and standardised analysis. Under the EU Fertilising Products Regulation, plant biostimulant claims must be substantiated, and in India the move from provisional to full registration has significantly reduced the number of approved biostimulant products. Suppliers are responding with research partnerships, trial networks and digital agronomy tools, which raise the cost of competing but reward quality-focused companies.
Raw Material and Logistics Challenges
High-quality humate deposits are geographically concentrated in regions such as North Dakota, New Mexico and Utah in the United States, Alberta in Canada, the Latrobe Valley in Australia and several Chinese provinces. Mining permits, environmental requirements and the low value-to-weight ratio of granular humates increase logistics costs for distant markets. Suppliers without integrated raw material access are exposed to supply and price risks, while those with integrated deposits are expanding exports to Asia, Latin America and Europe.
The humic acid value chain comprises four principal stages, from the sourcing of humate-bearing raw materials to application by growers.
Value addition is concentrated in the processing and formulation stage, where extraction efficiency, product consistency and formulation know-how determine margins. Integrated suppliers that control humate deposits and processing capture a larger share of value and are better able to guarantee consistent humic acid content.
Humic acid products are regulated as fertilizers, soil amendments, soil improvers or plant biostimulants depending on the jurisdiction and label claims. The key regulations by major region are summarised below.

Partnerships between CDMOs and instrumentation vendors should accelerate standard datasets for comparability across sites, improving forecasting models used in capacity planning.
Longer horizon, organoid and microphysiological adoption may reshape segment mix; teams that invest early in assay interoperability and cloud QC hooks are better positioned to capture upside without fragmenting their analytics stack.

Omnia is a 73-year-old South African industrial chemicals group that has repositioned itself as a two-engine primary-sector supplier: crop nutrition (Agriculture) and mining explosives and metallurgical chemicals (Mining, under the BME brand). Both engines are underpinned by the Sasolburg nitric-acid and ammonium-nitrate complex, one of the largest in the SADC region. The group has been rebuilt since its 2019 recapitalisation from a debt-stressed conglomerate into a net-cash, high-payout business. In FY26 it reported R24.2 billion revenue, a 9.0% operating margin and R1.68 billion net cash excluding leases. Its differentiators are its integrated ammonia-derivative supply chain, the Nutriology® agronomy model, AXXIS™ electronic initiation, and a growing international mining footprint in Indonesia, Canada and Australia. The legacy Chemicals segment has been largely exited. On 14 September 2026 the board agreed to recommend a R21.8 billion cash takeover by India's Solar Industries. Omnia is therefore now best analysed as a pending-take-private situation backed by strong standalone fundamentals. --- ### Company's own description In its FY26 results, Omnia describes itself as a diversified chemicals group supplying chemicals, specialised services and solutions to the agriculture, mining and chemicals application industries [FY26-LF]. It says it combines technical innovation with intellectual capital to add value across the supply and service chain. It also says its solutions promote the responsible use of chemicals and are shifting towards cleaner technologies. The group's stated purpose is "innovating to enhance life, together creating a greener future" [IAR26]. The company groups its activities into three reporting industries: Agriculture, Mining and Chemicals. These are supported by a shared Manufacturing and Supply Chain capability centred on Sasolburg [FY26-LF]. ### Independent characterisation Economically, Omnia is a vertically integrated nitrogen-chemistry platform with two value-added downstream channels. **Upstream.** Omnia buys ammonia, historically mainly from a key domestic supplier that underwent extended shutdowns in FY26, and phosphate rock. At Sasolburg it converts these into: - nitric acid - ammonium nitrate (AN) solution - porous granular and prilled AN - ANCN dual salt and calcium nitrate - nitrophosphate-derived intermediates - granulated NPK fertilizers **Downstream channel 1: Agriculture.** Product is sold through a technical-advisory model (Nutriology®) to commercial and small-scale farmers, cooperatives and governments in South Africa and the Rest of Africa. Internationally, the group sells higher-margin biostimulants (humates, fulvates, kelp, microbials) from Australia, Brazil and the USA. **Downstream channel 2: Mining (BME).** AN feeds bulk emulsion explosives, which are delivered by mobile manufacturing units and bundled with AXXIS™ electronic detonators, blast-design software and on-bench services. BME Metallurgy supplies flotation, solvent-extraction and ammonia-derivative reagents to mineral processors. **Residual: Chemicals.** After the FY25–FY26 restructuring, this is a Bulk Trade business that monetises the group's ammonia-derivative and bulk-liquid logistics, plus a Water Care business that is held for sale. **The economic logic.** The integrated asset base lets Omnia allocate scarce AN between agriculture (seasonal) and mining (year-round). It secures supply when competitors face force majeure, and it earns margin on third-party ammonia-derivative sales. These points recur in every results commentary from FY23 to FY26. ### Revenue model Omnia is overwhelmingly a product business. It has no disclosed subscription or licensing revenue. Software and AXXIS™ technology are bundled into blasting contracts, and part of Mining RSA revenue is cost recovery for services and technology [FY26-LF]. Sources: [FY23-LF] for FY22–FY23; [FY25-LF] for FY24–FY25; [FY26-LF] for FY26. In FY26, services were most significant in Mining: R601 million of R9,816 million Mining revenue, or 6.1%. This reflects BME's blasting-services content [FY26-LF]. ### Value-chain position, customers and end markets Source: [FY26-LF]; [IAR26].
