Fertigation cost per hectare and system prices: bands by system type and how to get comparable quotes
Fertigation cost per hectare depends on system type more than on area: roughly USD 400–1,500/ha for open-field drip on a shared head station, USD 2,000–6,000/ha for polyhouses, USD 8,000–20,000/ha for high-tech free-drain greenhouses, and USD 20,000–45,000/ha for recirculating hydroponics. Head station prices run from USD 3,000 for a manual venturi unit to USD 300,000+ for recirculating systems. This page sets out the bands, the drivers behind them, and what a supplier needs before a quote means anything.
Fertigation system prices fall into clear bands: manual venturi head stations USD 3,000–9,000, semi-automatic USD 12,000–35,000, automated commercial units USD 35,000–90,000, and recirculating hydroponic systems USD 90,000–300,000+. Per hectare, planning ranges are USD 400–1,500 for open-field drip, USD 2,000–6,000 for polyhouse, USD 8,000–20,000 for high-tech greenhouse and USD 20,000–45,000 for recirculating hydroponics.

Indicative fertigation head station CAPEX bands
Bands are indicative planning ranges for the head station itself — excluding field mainlines, drip laterals, civil works, fertilizer stock and installation labour where these are contracted separately.
| Head station class | Typical scope | Indicative CAPEX | Typically suited to |
|---|---|---|---|
| Venturi-based, manual | Screen filter, 1–2 venturi channels, manual valves | USD 3,000–9,000 | Open-field blocks up to ~10 ha, single recipe |
| Semi-automatic dosing | Sand + disc filtration, 3–4 dosing pumps, EC/pH monitoring | USD 12,000–35,000 | Polyhouse and open-field with variable recipes |
| Automated head unit | 4–6 channels, closed-loop EC/pH, mixing tank, controller, remote access | USD 35,000–90,000 | Commercial greenhouse 1–5 ha, high-value crops |
| High-tech / recirculating | 6–8 channels, dual mixing, drain recovery, UV or slow-sand disinfection, climate-computer integration | USD 90,000–300,000+ | Hydroponic and semi-closed greenhouses above 2 ha |

Fertigation system cost per hectare by system type
The same head station serves very different areas, so cost per hectare is set by the system type, not by the unit price alone. These are planning ranges for the fertigation scope — head station, dosing, control and the fertigation share of the field distribution — on an irrigated hectare.
| System type | Fertigation cost per hectare | Typical head station class | What is included |
|---|---|---|---|
| Open-field drip, shared head station | USD 400 – 1,500 /ha | Venturi or semi-automatic | Filtration, 1–3 dosing channels, sector valves, monitoring only |
| Polyhouse / naturally ventilated greenhouse | USD 2,000 – 6,000 /ha | Semi-automatic to automated | Disc/media filtration, 3–4 channels, EC/pH control, sector automation |
| High-tech greenhouse, free-drain substrate | USD 8,000 – 20,000 /ha | Automated head unit | Closed-loop EC/pH, mixing tank, 4–6 channels, climate-computer integration |
| Recirculating hydroponics / semi-closed | USD 20,000 – 45,000 /ha | High-tech recirculating | Drain collection, UV or slow-sand disinfection, dual mixing, re-dosing, full logging |
Planning ranges only, never a quotation and never a SeedMatchGroup price. Peak flow, water analysis and control ambition move these figures more than area does. Final numbers require supplier, agronomist and engineering review.
Fertilizer supply cost: what the recurring line is made of
Equipment is the one-off; soluble fertilizer and acid are the recurring cost, and they behave completely differently. Fertilizer pricing moves with commodity markets, origin, packaging and shipment size, so no fixed price per tonne belongs on a planning page — but the cost structure can be scoped precisely before any supplier is approached.
- •Product form: technical-grade water-soluble NPK, straight salts and chelated micronutrients each price differently from bulk granular product.
- •Water analysis drives the recipe: bicarbonate, sodium and chloride decide acid consumption and which salts are usable at all.
- •Volume and shipment size: annual contracted tonnage and full-container shipments change landed cost far more than the unit price quoted.
- •Landed cost, not ex-works: freight, duty, inland transport, storage and registration are the difference between two offers that look identical.
- •Registration and documentation: local fertilizer registration and certificates of analysis are a condition of import in many markets.
What actually moves the price
- •Dosing channel count: each additional acid or stock channel adds a pump, sensor, tank and control logic.
- •Injection method: venturi is cheap but pressure-hungry; piston or diaphragm dosing pumps hold accuracy at variable flow.
- •Water quality: iron, manganese, hardness or high bicarbonate can force acid dosing, oxidation and extra filtration stages ahead of the unit.
- •Filtration class: screen vs disc vs media, automatic backflush, and the redundancy required for continuous irrigation.
- •Control level: monitor-only, closed-loop EC/pH, or full recipe management integrated with the climate computer.
- •Recirculation: drain collection, disinfection (UV, heat, slow sand) and re-dosing can double the head station scope.
- •Peak flow: m³/h at design pressure sizes pumps, pipe diameters, valves and the cabinet, more than area alone does.
- •Materials and certification: PP vs stainless, IP rating, CE/UL compliance and food-safety documentation for export crops.
OPEX drivers to model alongside the CAPEX
- •Pumping energy at design flow and pressure, and how many hours a day the station actually runs.
- •Sensor consumables: EC/pH probe replacement and calibration solution on a quarterly cycle.
- •Filter maintenance: backflush water losses, media replacement, disc cleaning labour.
- •Acid and fertilizer consumption, which follows water quality and crop programme rather than equipment brand.
- •Spare parts holding for dosing pumps and solenoids where downtime stops irrigation.
What suppliers need before they can quote
- •Irrigated area in hectares and whether the project is phased.
- •Design peak flow (m³/h) and required pressure at the head.
- •A recent water analysis: EC, pH, bicarbonate, hardness, iron, manganese, chloride, sodium.
- •Crop and growing system: soil, substrate, or recirculating hydroponics.
- •Number of independent irrigation sectors and valves to be controlled.
- •Desired number of stock tanks and dosing channels, including acid.
- •Power supply available at the head station and whether backup is required.
- •Automation ambition and any climate computer or SCADA it must integrate with.
Quote-readiness checklist
- •Water analysis less than 12 months old.
- •Sector map with valve count and the longest run from the head.
- •Stated recirculation decision: free-drain or recirculating.
- •Scope statement: head station only, or head station plus field distribution and installation.
- •Named project owner, budget band in USD and target commissioning window.
Common risks on fertigation projects
- •Quotes compared on channel count while filtration and control scope differ silently.
- •Water analysis taken after the equipment is specified, forcing retrofit of pre-treatment.
- •Undersized mixing tank so recipe changes lag behind irrigation demand.
- •Controllers supplied without local support or training, leaving the unit run in manual.
- •Recirculation planned in phase two but no space, drain fall or disinfection allowance left in phase one.

FAQ
Indicatively USD 3,000–9,000 for a manual venturi unit, USD 12,000–35,000 semi-automatic, USD 35,000–90,000 for an automated commercial head unit, and USD 90,000–300,000+ for recirculating hydroponic systems. Final figures require supplier and engineering review.
As a planning range: roughly USD 400–1,500 per hectare for open-field drip on a shared head station, USD 2,000–6,000 per hectare for a polyhouse, USD 8,000–20,000 per hectare for a high-tech free-drain greenhouse, and USD 20,000–45,000 per hectare for recirculating hydroponics. Peak flow, water quality and control level move those figures more than area does.
Soluble fertilizer and acid are a recurring cost that follows commodity markets, origin, packaging and shipment size, so no fixed price per tonne is meaningful on a planning page. What can be fixed in advance is the specification and the landed-cost basis — freight, duty, inland transport and documentation — so supplier offers are comparable.
Only loosely. Peak flow, dosing channel count, water quality and control level drive the price far more than area. A 2 ha hydroponic project can carry a larger head station than a 30 ha open-field block.
For open-field drip with a shared head station, the head unit typically lands in the low hundreds of USD per hectare; for greenhouse hydroponics it can exceed USD 20,000 per hectare because of dosing accuracy, disinfection and recirculation.
Closed loop is worth it where recipes change frequently, water quality varies, or crop value makes deviation costly. Stable water and a single recipe can be run reliably on monitoring plus proportional dosing.
No. SeedMatch Group is an independent project sourcing and RFQ platform. It does not manufacture, install, finance or operate equipment, and it does not publish supplier contact details.

Yes, in substrate and hydroponic systems, but recirculation adds drain collection, disinfection and re-dosing to the head station and should be scoped from the start rather than retrofitted.
Lead times vary by configuration and origin, commonly several weeks to a few months. SeedMatch does not promise availability or delivery dates on behalf of suppliers.
