The global Liquid Ammonium and Liquid Potassium Thiosulfate fertilizer market addresses one of the most critical nutritional gap in modern commercial agriculture: the consistent, agronomically effective supply of plant-available sulfur alongside complementary macronutrients — nitrogen and potassium — in a single, clear liquid fertilizer format that integrates seamlessly with the fluid fertilizer application systems that are the backbone of large-scale commercial crop production in North America and progressively across global agricultural markets. As both soil sulfur deficiency and farmer demand for operationally efficient, multi-nutrient liquid fertilizer solutions continue to grow globally, the ATS and KTS product category occupies an increasingly important strategic position in the specialty liquid fertilizer landscape.

This comprehensive market research report, published by Chem Reports, delivers a data-driven analysis of the global Liquid Ammonium Thiosulfate (ATS) and Liquid Potassium Thiosulfate (KTS) market. The study covers the historical period 2020 to 2024, designates 2025 as the base year, and provides a detailed forward-looking market forecast through 2036. The analysis encompasses two product type segments, five application categories, seven regional markets, and strategic profiling of eleven leading manufacturers. The US market is a uniquely significant reference market — Tessenderlo Group commands more than 43.24% of the US market, the KTS segment records 192 K MT in US sales (15.91% of combined ATS + KTS volume), and KTS pricing of approximately USD 1,301 per metric ton reflects the segment's premium fertilizer positioning.

Ammonium thiosulfate (ATS), bearing the CAS Registry Number 7783-18-8 and the molecular formula (NH₄)₂S₂O₃, is the ammonium salt of thiosulfuric acid. In its crystalline solid form it presents as a white, hygroscopic material with a characteristic ammoniacal odor that is readily soluble in water but sparingly soluble in acetone and essentially insoluble in ethanol and diethyl ether. For agricultural liquid fertilizer applications, ATS is manufactured and marketed as a clear, stable aqueous solution containing approximately 12% total nitrogen (N) and 26% sulfur (S) by weight — a nutrient composition that reflects the compound's dual role as both a nitrogen and sulfur nutrition carrier. ATS solution is compatible with nitrogen solutions and NPK liquid fertilizer blends at neutral or slightly acidic pH, making it a versatile additive to existing liquid fertilizer programs. Its compatibility with clear liquid blends and suitability for suspension fertilizer applications across a wide range of mixing ratios makes ATS the most widely used liquid sulfur fertilizer in commercial agriculture globally.

Potassium thiosulfate fertilizer solution (KTS) is a clear liquid fertilizer product containing approximately 25% potassium expressed as K₂O and 17% sulfur — a nutrient analysis that is commonly referenced in the agricultural industry as 0-0-25-17S. KTS provides plant-available potassium and sulfur in a single, compatible liquid format suited to fertigation systems, liquid blending operations, and foliar application programs. Both ATS and KTS deliver sulfur in the thiosulfate (S₂O₃²⁻) form, which undergoes gradual oxidation to plant-available sulfate (SO₄²⁻) in the soil environment through microbial oxidation — providing a degree of controlled release relative to immediately water-soluble sulfate fertilizers, which can reduce leaching losses and extend the period of plant-available sulfur supply from a single application. The United States is the world's most developed market for both ATS and KTS, with the market relatively concentrated — the top five companies commanding more than 52% of market revenue — but still exhibiting a meaningful fragmented mid-tier of regional suppliers.

3.1 Key Growth Drivers

•       Growing Global Soil Sulfur Deficiency: Sulfur deficiency in agricultural soils has been progressively intensifying across both North American and global farming regions over the past three decades, driven by two converging trends: the dramatic reduction in atmospheric sulfur deposition from industrial emissions following successful acid rain regulation and industrial desulfurization investments, and the growing use of high-purity, sulfur-free nitrogen and phosphate fertilizer formulations that historically contributed meaningful incidental sulfur inputs to agricultural fields. As soils progressively deplete their native sulfur reserves without replacement through atmospheric deposition or fertilizer application, yield-limiting sulfur deficiency is emerging in crops that were historically considered adequately supplied — creating structural demand for purpose-applied sulfur fertilizers including ATS and KTS.

•       Premium Cash Crop and Specialty Crop Sulfur Demand: Cash crops — including fruits, vegetables, oilseeds, cotton, and specialty crops in high-value horticultural production — have among the highest sulfur requirements of all agricultural plant types, particularly in the context of protein synthesis, allyl sulfide compound production (responsible for the distinctive flavors and aromas of allium crops), and overall crop quality. The growing global market for premium food products, expanding fresh produce consumption, and the significant economic value per acre of specialty crop production are driving high investment in balanced crop nutrition programs that specifically address sulfur, creating premium per-unit-area demand for ATS and KTS in irrigation-based fertigation programs serving these high-value applications.

•       Corn and Cereal Grain Production Volume Growth: Corn (maize) is the single largest application for both ATS and KTS fertilizers in the United States and remains the dominant crop-specific driver of liquid thiosulfate fertilizer demand globally. Corn's high sulfur requirement — with sulfur playing critical roles in enzyme function, chlorophyll synthesis, and protein accumulation — makes it highly responsive to sulfur fertilization in deficient soils, translating sulfur application directly into yield improvement that is economically compelling for large-scale corn producers. Growing global corn production for food, feed, and ethanol biofuel purposes sustains and expands the corn fertilizer application's foundational demand role for the ATS and KTS market.

•       Liquid Fertilizer System Adoption and ATS/KTS Compatibility Advantages: North American commercial agriculture operates extensively on large-scale liquid fertilizer application systems — including nurse tank-equipped planters, sidedress liquid fertilizer applicators, and center pivot fertigation infrastructure — that are specifically engineered for liquid fertilizer products. ATS and KTS solutions' clarity, stability, compatibility with nitrogen solutions and NPK liquid blends, and suitability for suspension fertilizer formulation make them ideal components in liquid fertilizer programs without requiring specialized equipment or separate application passes. This agronomic integration convenience sustains consistent demand from the substantial established base of liquid fertilizer system operators in North America.

•       Nitrification Inhibition Function of ATS: A commercially important secondary function of ATS beyond its direct sulfur nutrition role is its effectiveness as a nitrification inhibitor at appropriate application rates — reducing the rate at which ammonium nitrogen in soil is converted to nitrate nitrogen by soil bacteria. By slowing nitrification, ATS application alongside urea or UAN (urea-ammonium nitrate) nitrogen fertilizers can improve nitrogen use efficiency, reduce nitrate leaching losses, and decrease nitrous oxide greenhouse gas emissions from fertilized soils. This dual-function value proposition — sulfur nutrition plus nitrogen use efficiency improvement — enhances ATS's economic value per acre and creates growing interest in precision nitrogen management programs that leverage ATS as both a nutritional and efficiency tool.

•       Expanding Agricultural Markets in Developing Economies: While the US market is the most developed global market for liquid ATS and KTS, the growing adoption of advanced liquid fertilizer technology in Brazil, Argentina, Southeast Asia, and other intensifying agricultural regions is progressively expanding the global addressable market. High-value crop production, fertigation expansion, and awareness of soil sulfur management among sophisticated agronomists in developing countries is creating growing international demand for ATS and KTS solutions as awareness of these products' agronomic benefits spreads beyond the historically dominant North American market.

3.2 Market Restraints

•       US Market Maturity and Near-Stagnant Growth: The United States represents the largest single national market for liquid ATS and KTS globally, and that market has reached a high level of maturity characterized by established supplier relationships, well-penetrated distribution networks, and limited dramatic volume growth opportunity. As the primary global market matures, overall market revenue growth is constrained by the slow pace of new market development in international geographies sufficient to offset the limited US growth rate.

•       Downward Price Pressure on ATS: ATS pricing has exhibited a general downward trend driven by expanding production capacity, the increasing price competitiveness of multiple producers, the maturation of the US market, and the influence of ammonia and sulfur raw material price cycles on production economics. The narrowing price differential between branded ATS products and private-label or commodity equivalents is compressing gross margins across the industry and creating purchasing leverage for large agricultural cooperative and retailer accounts. Sustained price compression limits revenue growth even where volume growth is positive.

•       Ammonia and Sulfur Feedstock Cost Volatility: Both ATS and KTS are produced from ammonia or potassium-based feedstocks combined with sulfur or thiosulfuric acid chemistry. Ammonia prices — influenced by global natural gas costs, global nitrogen fertilizer supply and demand, and trade flows — are subject to significant volatility that creates ATS production cost uncertainty. Similarly, sulfur and thiosulfuric acid feedstock costs are influenced by global refinery and natural gas processing sulfur recovery volumes and demand from multiple industrial users.

•       Geographic Concentration Creating International Development Challenge: The exceptional concentration of ATS and KTS manufacturing and consumption in the United States — compared to the rest of the world — creates a structural market development challenge: building the distribution infrastructure, agronomist awareness, and farmer adoption required to replicate the North American market's depth in international agricultural markets takes time, capital, and sustained agronomic education investment. The slow pace of international market development constrains global market growth to a rate closer to mature US market dynamics than to global agricultural expansion trends.

3.3 Market Opportunities

•       Nitrogen Use Efficiency Market Development: The growing regulatory and commercial focus on reducing nitrogen losses from agricultural systems — driven by nitrate water quality regulation, greenhouse gas reduction targets, and farm economic efficiency imperatives — creates a compelling growth opportunity for ATS in its nitrification inhibition role. Positioning ATS as a nitrogen use efficiency enhancer alongside conventional nitrogen fertilizer programs, rather than solely as a sulfur fertilizer, opens access to a broader market segment motivated by both yield optimization and environmental compliance.

•       Fertigation System Expansion in Irrigated Agriculture: The global expansion of irrigated agriculture — driven by the growing adoption of drip irrigation and sprinkler systems in water-limited production regions of South America, Middle East, South and Southeast Asia, and Australia — creates a natural distribution platform for liquid ATS and KTS, which can be introduced through irrigation water as part of fertigation programs. Each new hectare of irrigated agricultural land equipped with fertigation capability represents a potential new ATS/KTS consumption point.

•       Organic Sulfur and Balanced Nutrition Premium Market: Growing consumer and regulatory interest in production practices that minimize synthetic chemical inputs and emphasize balanced plant nutrition is creating interest in thiosulfate sulfur fertilizers — which supply sulfur in a gradually oxidizing form that mimics some aspects of natural sulfur cycling — as part of sustainable farming programs. Premium market positioning of ATS and KTS for high-value, sustainability-conscious farming operations could support premium pricing relative to commodity sulfur fertilizer alternatives.

•       International Market Development — South America and Southeast Asia: Brazil's massive agricultural sector — the world's largest soybean, sugarcane, and increasingly corn producing nation — represents a substantial untapped opportunity for liquid ATS adoption in sulfur-deficient Cerrado and other agricultural soils where soybean production's high sulfur requirement is progressively encountering limitations from soil sulfur depletion. Southeast Asia's growing high-value crop sector similarly presents international expansion opportunities for ATS and KTS manufacturers willing to invest in market development.

•       Product Innovation in Thiosulfate-Based Fertilizer Blends: Development of novel specialty fertilizer formulations that combine ATS or KTS with additional micronutrients, biostimulants, or other crop nutrition components — creating multi-nutrient liquid fertilizer products that address multiple nutritional needs simultaneously in a single application — represents a product innovation opportunity that could support premium pricing and differentiation from commodity thiosulfate products.

4.1 By Product Type

The global Liquid Ammonium and Liquid Potassium Thiosulfate market is divided into two distinct product categories — Liquid Ammonium Thiosulfate (ATS) and Liquid Potassium Thiosulfate (KTS) — each defined by its nutrient composition, primary agronomic role, application method preferences, and commercial positioning in the agricultural fertilizer market.

•       Liquid Ammonium Thiosulfate (ATS): ATS is the dominant product type in the global Liquid Thiosulfate fertilizer market by volume, reflecting its broader agronomic applicability across the full spectrum of row crop production where both nitrogen and sulfur nutrition are simultaneously addressed. ATS solution is readily incorporated into standard nitrogen fertilizer programs — blended with UAN, urea solution, or anhydrous ammonia post-application — enabling farmers to add sulfur nutrition to existing nitrogen application programs without requiring separate equipment passes or new application systems. The compound's additional value as a nitrification inhibitor at appropriate ratios makes it attractive for precision nitrogen management programs. The US market for ATS is served by a combination of large-scale producers — Tessenderlo Group as the dominant market leader, complemented by Martin Midstream Partners, Poole Chem, Rentech Nitrogen, Koch Fertilizer, and Kugler — and a fragmented tier of regional distributors and blenders. ATS pricing has historically trended downward as production capacity has grown and market competition has intensified, though it remains subject to ammonia feedstock price volatility.

•       Liquid Potassium Thiosulfate (KTS): KTS occupies a smaller but more premium-positioned segment within the liquid thiosulfate fertilizer market, providing a unique combination of two essential plant nutrients — potassium and sulfur — in a chloride-free, clear liquid format that is particularly valued in the production of chloride-sensitive crops (including fruits, vegetables, tobacco, and certain specialty crops), in fertigation programs where clear liquid compatibility is essential, and in foliar application programs where leaf burn from chloride salts in conventional muriate of potash is a concern. US KTS sales of 192 K MT represent approximately 15.91% of combined ATS plus KTS volume, and KTS commands a significantly higher price per metric ton than ATS — approximately USD 1,301 per MT as of the most recent reference price, up from a lower base in 2016, reflecting both the premium positioning of chloride-free potassium sources in high-value crop markets and the inherently higher production cost of KTS relative to ATS. Tessenderlo Group, Mears Fertilizer, Plant Food, and Hydrite Chemical are the primary KTS suppliers in the US market.

4.2 By Application

•       Corn Fertilizer: Corn is the anchor application for both ATS and KTS in the United States and globally, reflecting the crop's high sulfur requirement, its dominant position in North American row crop agriculture by planted area, and the well-established role of ATS in corn nitrogen programs as a compatible sulfur source and nitrification inhibitor. Sulfur applications to corn are well-supported by decades of agronomic research demonstrating consistent yield responses to sulfur supplementation in deficient soils, and the large-scale, liquid fertilizer-intensive production systems used in commercial corn growing in the US Corn Belt create a highly efficient distribution and application framework for ATS. The continued growth of global corn production for food, feed, and biofuels is the most important single driver of ATS market volume through the forecast period. Traditional corn application uses are expected to sustain steady demand even as newer applications develop.

•       Grain Fertilizer: Beyond corn, the grain fertilizer application encompasses wheat, barley, sorghum, rice, and other cereal grain crops where ATS provides sulfur and nitrogen nutrition in liquid fertilizer programs and where the nitrification inhibition function of ATS can improve nitrogen use efficiency in high-yield grain production systems. Wheat is a significant ATS consumer in both North American production and in European markets where precision liquid fertilizer programs are progressively adopted. Growing global cereal grain production requirements for food security, supported by increasingly intensive fertilization practices in major producing regions, sustain consistent demand from the grain fertilizer application segment.

•       Cash Crop Fertilizer: The cash crop application segment encompasses high-value crops including fruits, vegetables, oilseeds, cotton, sugarcane, tobacco, and specialty horticultural crops, where the economic value per acre justifies premium-grade, specialty fertilizer investment including ATS and particularly KTS. This segment is identified as a high-growth opportunity, reflecting the growing attention to precision nutrition in high-value crop production, the expansion of irrigated high-value crop production globally that facilitates fertigation delivery of liquid KTS, and the premium pricing achievable in specialty crop markets that supports higher agronomic input investment per acre. Cash crop farmers' sensitivity to crop quality attributes — and sulfur's important role in quality parameters including protein content, flavor compound production, and produce appearance — sustains premium willingness-to-pay for effective sulfur fertilizer programs.

•       Other Agricultural Applications: This segment encompasses additional crop-specific ATS and KTS applications including oilseed crops (canola/rapeseed, sunflower, soybeans), legume crops (alfalfa, clover), pasture and hay production, perennial crops (orchards, vineyards), and emerging precision agriculture programs in non-traditional crop categories. Oilseed crops — particularly canola/rapeseed — have among the highest sulfur requirements of all major field crops, making them highly responsive to ATS application, and the growing global oilseed production area represents a meaningful growth opportunity for ATS consumption.

•       Industrial Applications: Beyond agricultural uses, ammonium thiosulfate has industrial applications as a photographic fixer and thiosulfate chemistry reagent — historically used in silver recovery and photographic film processing, and more recently in gold and silver leaching operations in the mining industry as an alternative to cyanide-based gold leaching chemistry. KTS similarly finds specialty industrial uses. While industrial applications represent a small fraction of the overall market, they contribute to demand diversification and support production economics for manufacturers.

5.1 North America

North America — and specifically the United States — is overwhelmingly the world's most developed, most mature, and most commercially concentrated market for liquid ATS and KTS fertilizers. The US market reflects decades of product development, agronomic education, distribution infrastructure investment, and adoption of liquid fertilizer systems in commercial row crop agriculture that has created a uniquely deep domestic market for these products. Tessenderlo Group commands more than 43.24% of the US ATS and KTS market, reflecting its dominant position through integrated production, distribution, and supply chain scale advantages. The US market's maturity is reflected in its near-stagnant volume growth trajectory, downward ATS price pressure, and the well-established competitive landscape among the major suppliers. Canada contributes additional demand from its significant cereal grain and oilseed production sectors, particularly for ATS in Western Canadian wheat and canola production systems where sulfur deficiency in cultivated soils is well-documented and ATS adoption is growing.

5.2 Europe

Europe represents a meaningful and growing ATS and KTS market, with demand driven by the continent's intensive agricultural production systems, the progressive recognition of soil sulfur deficiency in European arable soils depleted by decades of emission reduction success, and the adoption of precision liquid fertilizer technology in advanced farming operations. Germany, France, UK, and Poland are among the primary European demand markets where ATS is used in liquid nitrogen programs on wheat, barley, and oilseed rape (canola) — a crop with particularly high sulfur requirements that responds strongly to ATS-supplied sulfur. European agricultural cooperatives and fertilizer distributors are increasingly incorporating ATS into liquid fertilizer programs as awareness of sulfur deficiency impacts on yield and quality grows among precision-farming operators.

5.3 China

China represents a developing opportunity for liquid ATS and KTS adoption, with the country's large and intensively managed agricultural sector progressively moving toward premium fertilizer inputs as farm profitability demands precision nutrition investment in high-value crop production. China's extensive irrigated agriculture — including its large vegetable, fruit, and specialty crop sectors served by drip and sprinkler fertigation systems — creates potential for KTS adoption in chloride-sensitive, high-value crop nutrition programs. The country's domestic thiosulfate chemistry manufacturing capability is developing, and international product awareness is progressively spreading through agronomic education channels.

5.4 Japan

Japan's agricultural market is characterized by high-value, intensively managed production systems where premium fertilizer inputs are accepted in support of food quality objectives. The country's significant horticultural production — fruits, vegetables, tea, and other specialty crops requiring balanced nutrition without chloride — creates a natural premium market niche for KTS. Japan's well-developed fertigation infrastructure in protected horticulture and fruit production provides an ideal delivery platform for liquid KTS integration.

5.5 India

India is a growing market for ATS and KTS, driven by the country's expanding high-value crop production sector, growing awareness of soil sulfur deficiency in intensively cultivated soils that have been heavily fertilized with N and P but received little sulfur supplementation, and the progressive adoption of fertigation systems in irrigated vegetable, fruit, and sugarcane production. India's large oilseed production sector — where sulfur deficiency in mustard, groundnut, and soybean crops is well-documented — represents a meaningful ATS demand opportunity. International fertilizer companies and domestic specialty fertilizer distributors are progressively introducing ATS and KTS to the Indian agricultural market.

5.6 Southeast Asia

Southeast Asia offers meaningful growth potential for liquid ATS and KTS, particularly in the region's expanding high-value export crop production sectors — including fresh vegetables, fruits, floriculture, and specialty crops — where precision nutrition programs and fertigation delivery create natural demand for compatible liquid fertilizer products. Thailand, Malaysia, Vietnam, and Indonesia collectively represent a growing addressable market as commercial agriculture sophistication increases and irrigated area expands.

5.7 Other Regions

South America — particularly Brazil and Argentina — represents a strategically important international opportunity for ATS expansion, reflecting the continent's vast agricultural area, the progressive recognition of soil sulfur depletion in weathered Cerrado and Pampas soils under intensive crop production, and the growing adoption of liquid fertilizer technology in large-scale commercial agriculture. Brazil's massive soybean and corn production sectors represent potential high-volume ATS demand markets if product adoption can be accelerated through targeted agronomic education and distribution network development. The Middle East and Africa represent longer-term opportunities in expanding irrigated horticulture and commercial crop production contexts.

The global Liquid ATS and KTS fertilizer market is notably concentrated at the top — with Tessenderlo Group holding more than 43.24% of the US market, and the top five manufacturers collectively accounting for more than 52% of total market revenue — yet remains fragmented in its mid-tier, where a number of regional producers, agricultural chemical distributors, and specialty fertilizer companies participate with comparable but smaller revenue contributions. This concentration-fragmentation duality reflects both the significant scale and supply chain advantages of the market leader and the limitations to scale in a product category where distribution logistics and regional agronomic relationships are important competitive factors. Competition is primarily based on supply chain reliability, product quality consistency, technical agronomic service support, price competitiveness, and proximity to agricultural customer delivery locations.
