Greenhouse Automation, Geothermal Heating and Fertigation Projects in Türkiye

Türkiye market context — greenhouse automation, geothermal-heated greenhouse and fertigation projects

Turkish protected agriculture concentrates in Antalya, Mersin, Adana and the Aegean, with a distinctive geothermal-heated cluster in Afyon, Aydın, Denizli, İzmir and Şanlıurfa where hot water supports year-round tomato production. The domestic supply chain manufactures structures, screens and irrigation components competitively, while climate computers, high-end sensing and some hydroponic components are imported. Projects range from upgrading legacy soil-grown poly houses to new high-tech glass with semi-closed climate. Export orientation toward Russia, Europe and the Gulf shapes quality and traceability requirements.

Main project types we see in this market

• •New high-tech glass or poly greenhouses with climate computers, 2–50 ha.
• •Geothermal-heated greenhouse projects with heat exchangers and distribution.
• •Automation retrofits: climate computers, screens, sensors and fertigation upgrades.
• •Substrate and hydroponic conversion from soil-grown production.
• •Cooling and ventilation upgrades for the summer window in southern provinces.
• •Packing, storage and traceability upgrades tied to export contracts.

Main crops and production systems

• •Tomato — the dominant protected crop, especially in geothermal projects.
• •Cucumber, pepper and aubergine under poly and glass.
• •Strawberry in gutters and substrate.
• •Leafy greens and herbs in hydroponic systems near cities.
• •Cut flowers in the Antalya region.
• •Rapid shift from soil to substrate in commercial new builds.

What project owners usually need

Most briefs that reach a supplier-ready state in this market cover the following scope.

• •Climate control and automation appropriate to both winter heating and summer cooling.
• •Geothermal heat exchange, distribution and corrosion management where applicable.
• •Fertigation with recirculation, EC/pH control and disinfection.
• •Screens (energy, shade) to manage heat loss and summer light.
• •Substrate systems and drainage for hydroponic conversion.
• •Traceability and quality systems aligned with export buyers.

Equipment and supplier categories

SeedMatch does not manufacture or install any of the below. These are the supplier categories a project of this type normally has to package and compare.

• •Greenhouse structures: glass, diffuse poly, gutters, vents, screens.
• •Heating: geothermal heat exchangers, boilers, pipe rail, buffer tanks.
• •Cooling and ventilation: fans, pads, fog, roof vents.
• •Climate computers, sensors, weather stations and SCADA.
• •Fertigation: dosing units, EC/pH control, drain tanks, UV or heat disinfection.
• •Substrate systems: slabs, gutters, hanging systems, crop wire.
• •Post-harvest: cold rooms, grading and packing lines.

Indicative CAPEX bands

Indicative only. Not financial advice, not agronomic advice and not engineering design. Final numbers require supplier, agronomist, engineer and local regulatory review, and change with steel prices, freight, duties and site conditions.

What affects CAPEX

• •Structure tier: poly versus glass, gutter height and span.
• •Heating source and distribution scope, particularly geothermal well and heat-exchange works.
• •Automation depth: basic controllers versus full climate computers with screens.
• •Substrate conversion, including drainage and disinfection.
• •Cooling capacity for southern summer conditions.
• •Import content for controls and sensing versus locally manufactured structures.

What affects OPEX

• •Heating energy — dramatically lower where geothermal is available.
• •Electricity for pumps, fans and controls.
• •Labour for high-wire crop work.
• •Fertilizer and substrate consumables.
• •Crop protection and biological control programmes.
• •Maintenance of screens, heat exchangers and dosing calibration.

What affects water use and crop yield

• •Heating and screening strategy control transpiration and winter production capacity.
• •Substrate plus recirculation reduces water and fertilizer use materially.
• •Geothermal water chemistry must be isolated from irrigation water — cross-contamination risks the crop.
• •Summer cooling determines whether the crop can be held or must be cleared.
• •Climate-computer setpoint quality is often worth more yield than additional hardware.

How fertigation and water efficiency affect project economics

Fertigation is where water, fertilizer and yield meet. Dosing accuracy decides how much of each fertilizer unit reaches the root zone, drainage strategy decides how much water and nutrient leaves the system, and water quality decides how much pre-treatment and maintenance the whole irrigation set will need for the next ten years.

• •Dosing accuracy: ±5% channel accuracy versus ±15% changes annual fertilizer spend and EC/pH stability, especially on high-value crops.
• •Recirculation: closed or semi-closed drain recovery can cut water and soluble fertilizer use materially, but adds disinfection (UV or heat), drain tanks and sodium management.
• •Water quality: bicarbonate, sodium, chloride, iron and boron levels drive acid dosing, filtration and whether reverse osmosis or blending is needed before the crop recipe can be met.
• •Uniformity: emitter uniformity below roughly 90% forces over-irrigation to protect the weakest block, wasting water, fertilizer and yield potential at the same time.
• •Fertilizer grade: fully water-soluble and chelated grades cost more per tonne but reduce clogging, filter cleaning and downtime versus commodity grades in drip systems.

What affects supplier selection

• •Ability to combine locally manufactured structures with imported controls.
• •Geothermal engineering references where the project uses hot water.
• •Local service network and Turkish-language technical support.
• •Documentation for export-oriented quality systems.
• •Delivery phasing that matches the planting calendar.
• •Clear scope split between structure, climate, irrigation and civil works.

What details are needed before suppliers can quote

A supplier cannot price a structure, an irrigation set or a fertigation unit from a crop name and a hectare count alone. These are the inputs that make a request quotable.

• •Province and site, with elevation and winter design temperature.
• •Hectares in phase 1 and total programme.
• •Heat source: geothermal (with well data and water chemistry), gas, biomass or none.
• •Crop and growing system, and target production calendar.
• •Water source, volume and laboratory analysis.
• •Electrical capacity and automation requirements.
• •Scope split with local contractors.
• •Budget band in USD and target commissioning quarter.

What SeedMatch does in this project type

• •Reviews the submitted project brief and flags what is missing before anything is sent out.
• •Normalises scope so every approached supplier quotes the same boundaries, exclusions and delivery terms.
• •Approaches suitable manufacturers, integrators or project partners — selected per brief, not from an open directory listing.
• •Structures returned proposals into a like-for-like comparison of scope, technical assumptions and commercial terms.
• •Stays supplier-neutral: SeedMatch does not manufacture, install, build, finance or resell any part of the project.

Who supplies the equipment?

Equipment comes from independent manufacturers, system integrators and local installation contractors. Supplier identities are shared with the buyer during a managed process, not published as an open marketplace listing, and SeedMatch is never a party to the supply contract — contracts are signed directly between the project owner and the supplier.

Why SeedMatch reviews the brief first

• •Unreviewed requests produce non-comparable quotes: different structures, different scope boundaries, different exclusions.
• •A review catches missing site data (water analysis, climate data, power availability) that would otherwise force suppliers to guess.
• •It protects the buyer's time: only suppliers plausibly able to serve the country, crop, scale and budget band are approached.
• •It protects supplier goodwill, which keeps response rates high for genuine commercial projects.

What makes a greenhouse or fertigation project quote-ready?

• •Site: country, coordinates or nearest town, plot size, orientation, access road, and whether the land is levelled.
• •Climate: design temperature extremes, humidity, wind and (where relevant) snow loads.
• •Water: source, available volume per day, and a laboratory analysis (EC, pH, Na, Cl, HCO₃, Fe, B, hardness).
• •Energy: grid capacity and reliability, diesel or gas availability, solar intent.
• •Crop plan: crop, variety class, target cycles per year and target yield.
• •Scope: which packages the supplier must quote and which the owner will contract locally.
• •Commercial: budget band, target commissioning date, incoterms, and who handles customs and civil works.

SeedMatch RFQ process

Timelines are indicative. Supplier availability, season and project complexity change response times, and SeedMatch does not guarantee that any supplier will quote.

Quote readiness checklist

• •Water laboratory analysis, less than 12 months old.
• •Site plan or coordinates with plot dimensions.
• •Climate data or nearest reference station.
• •Crop, growing system (soil, substrate, hydroponic) and target cycles.
• •Electricity capacity and backup arrangement.
• •Scope split: supply only, supply and install, or turnkey.
• •Budget band in USD and target commissioning quarter.
• •Decision process and who signs the contract.

What may block or delay supplier quotes?

• •No water analysis — fertigation and treatment scope cannot be priced.
• •Undefined scope boundary between supplier, civil works and local installation.
• •Budget band far below the technology level requested for the crop and climate.
• •Unclear land control, permits or import route for the equipment.
• •Requests below the USD 250,000 commercial threshold, or hobby-scale enquiries.

Common project risks

• •Geothermal well flow or temperature underperforming the design assumption.
• •Corrosion and scaling in geothermal heat-exchange circuits.
• •Currency volatility affecting imported control and sensing components.
• •Summer heat limiting production in southern provinces without adequate cooling.
• •Export market and logistics disruption affecting the business case.
• •Skill gaps in operating high-tech climate systems after commissioning.
