Demand is linked to the expansion of protected cultivation, repeated nutrient-solution preparation and increasingly measured root-zone dosing. Greenhouse operators and hydroponic growers are evaluating nutrient systems and biological additives that can work with existing irrigation equipment without creating mixing, sanitation or maintenance problems.

Controlled-environment agriculture strengthens demand

Greater control over irrigation and nutrient delivery is creating opportunities for specialized inputs used in soilless cultivation. On October 6, 2026, the U.S. Department of Agriculture's Agricultural Research Service (USDA-ARS) published research priorities covering climate-smart production and pest-management practices for nursery, greenhouse and protected-culture crops, including mineral inputs, substrate dynamics and water management.

These priorities reflect the operational issues that suppliers must address when developing products for protected cultivation. Nutrient concentration, source-water chemistry and compatibility with existing equipment can influence how consistently an additive performs during repeated crop cycles.

Where growth is fastest

FMI's country forecasts show that South Korea is expected to record the fastest growth among the five profiled markets between 2026 and 2036.

• South Korea — 11.7% CAGR: Public smart-greenhouse programs and monitored nutrient delivery create opportunities for products compatible with automated greenhouse equipment. The report identifies the country's 2027 ICT greenhouse construction program as a relevant development.
• United States — 11.4% CAGR: Domestic vegetable production and established specialty-input channels support opportunities for repeated nutrient use. USDA data cited by FMI indicates that domestic production supplied 93% of lettuce availability in 2025.
• Germany — 11.1% CAGR: Protected vegetable production supports recurring demand for fertigation inputs. Destatis reported 1,250 hectares of protected vegetables and output of 219,200 tonnes in 2025.
• United Kingdom — 10.7% CAGR: Protected cultivation creates demand for soluble inputs and controlled nutrient delivery, although water use and input costs can influence product trials. The report cites 866 hectares of protected vegetables and production of 258,000 tonnes in 2025.
• Japan — 9.8% CAGR: Established protected-horticulture infrastructure favors products compatible with existing injectors, sanitation procedures and crop protocols.

What leads the market

FMI identifies several leading segments across the market's product, crop, system, grower and sales-channel categories for 2026.

• Complete A/B nutrient systems — 42.1% of product-type revenue: Separating concentrated nutrient components helps manage compatibility before dilution and allows growers to adjust nutrient concentration for different crop stages.
• Leafy greens and herbs — 46.2% of crop demand: Short production cycles and repeated nutrient-solution preparation make these crops relevant for evaluating changes in nutrient availability and additive performance.
• Drip substrate systems — 40.7% of system demand: Controlled delivery allows growers to adjust nutrient concentration and irrigation frequency according to crop stage.
• Commercial greenhouses — 45.1% of grower-type revenue: Larger production areas support bulk purchasing and recurring nutrient requirements, while making formulation errors more consequential.
• Greenhouse suppliers — 41.7% of sales-channel revenue: Local product availability, source-water testing and mixing support can help growers assess new nutrient programs.

The hurdle: biological compatibility and reliable application

The main commercial challenge is ensuring that an additive remains compatible with the grower's water, nutrient solution, equipment and sanitation routine.

Water chemistry and stock concentration can affect mixing stability, while sanitation treatments may affect living microbial inputs. In recirculating systems, the same water pathway can distribute beneficial microorganisms as well as unwanted organisms. Growers therefore need application protocols that account for the specific product and production setup.

Research cited in the FMI report illustrates this issue. A study published in July 2025 examined ultraviolet water treatment and the survival of Escherichia coli in recirculating hydroponic systems. For suppliers of biological additives, such work reinforces the importance of evaluating product viability alongside the sanitation procedures used by commercial growers.

Recent developments and industry investment

Recent company developments show continued investment in biological crop solutions and specialized nutrient delivery.

• March 23, 2026: Yara International announced expanded research capabilities at its Hanninghof Research Centre in Germany, including laboratory facilities for developing and validating biological crop-nutrition and root-health formulations.
• July 8, 2025: Evogene announced completion of the transaction involving the sale of Lavie Bio's activities to ICL, adding microbial resources and biological discovery capabilities to ICL's portfolio.
• February 17, 2025: Haifa Group introduced Haifa Soluble DUO, a water-soluble fertilizer range designed to support calcium adjustment with lower accompanying nitrogen, chloride or sulfate.

FMI profiles the following companies among the notable participants: Canna, JR Peters, Masterblend, Netafim, Compo Expert, Haifa Group, Yara International and ICL Group.

The competitive field includes soilless nutrient-system specialists, fertigation providers and suppliers with biological-input capabilities. Competition depends on product compatibility, application support, distribution reach and the ability to demonstrate performance under commercial growing conditions.

Analyst perspective

“Commercial growers will repeat an additive only when mixing remains simple and crop response becomes visible within the production cycle. Products compatible with present dosing and sanitation practices will enter larger greenhouse blocks faster than complex biological programs.” — Nandini Roy Choudhury, Principal Consultant, Future Market Insights.

What this means for greenhouse operators and agricultural-input suppliers

1. Test compatibility before expanding application. Evaluate the product against source-water chemistry, nutrient concentration, injector settings and existing sanitation procedures. Confirm that the additive can be used without disrupting the current fertigation routine.
2. Measure performance within the crop cycle. Start with controlled trials that track relevant crop responses and application consistency. Compare results against the existing nutrient program before extending use across larger production blocks.
3. Prioritize practical application support. Provide crop-specific dosing instructions, mixing guidance and clear information about sanitation compatibility. For suppliers, these details can help reduce the operational uncertainty growers face when evaluating a new input.
