Crop and cultivation assessment
Soil, substrate or hydroponic production and the recipe structure supplied by the operation are reviewed.
CONTROLLED NUTRIENT PREPARATION AND DOSING
Greenhouse Fertigation Systems
We design greenhouse fertigation systems around the crop, cultivation method, water quality, irrigation zones and nutrient recipes to be applied.
From stock tanks and dosing pumps to EC and pH measurement and recipe automation, nutrient-solution preparation is assessed within one control structure.
- Recipe-based dosing
- EC and pH monitoring
- Zone-based application
- Automated logging and control
How Does a Greenhouse Fertigation System Work?
Fertigation applies plant nutrients with irrigation water under a defined recipe and controlled process. Concentrated fertilizers are prepared as stock solutions, while components that may react are kept in separate tanks. A and B stock tanks can be accompanied by a separate acid or pH adjustment line when the project requires it. Equipment, wetted materials and separation are selected through appropriate specialist assessment to manage incompatibility, precipitation and safe operation.
Dosing pumps or another injection method suited to the project transfer stock solutions into the main mixing water. Target values come from recipes provided by the operation, grower or relevant crop specialist. The system does not create agronomic recipes; it is configured to apply supplied targets within defined technical limits and control scenarios. Water quality and starting EC and pH values provide essential inputs for measurement and dosing design.
A Controlled Process from Recipe to Application
EC and pH sensors measure the prepared solution in the mixing unit. The controller compares readings with recipe targets and manages the appropriate dosing equipment. Separate recipes or schedules may be assigned to irrigation zones serving different crops or growth stages. The finished nutrient solution then enters the irrigation distribution system. Fertigation prepares and doses nutrients, while irrigation automation carries the solution to the selected zones.
Repeatable operation depends on regular calibration of probes and dosing equipment. Alarms may cover tank level, measurement range, flow status and EC or pH values outside set limits. Records help operators review programs and measured conditions. During commissioning, sensors, dosing lines, recipe changes, interlocks and alarm scenarios are tested together with the site’s safe operating procedures.
- Stock-solution preparationKeeping incompatible components separate in suitable tanks and materials.
- Controlled nutrient injectionManaging the selected dosing method against supplied recipe targets.
- EC and pH measurementMonitoring and controlling the values of the prepared solution.
- Recipe, zone and alarm managementAssigning programs and tracking records, status and warnings.

Designing tanks, dosing and measurement
Separation, injection method, sensor points and process flow are defined.
- 04
Selecting equipment and automation
Compatible tanks, pumps, valves, probes, controllers and alarms are specified.
- 05
Installation and irrigation integration
The preparation unit is connected to existing or new distribution through controlled interfaces.

Calibration, testing and commissioning
Measurements, dosing response, recipe changes, logging and alarm scenarios are tested.
The project schedule is established after water analysis, recipe structure, existing infrastructure, site and equipment scope are reviewed.
INTEGRATED GREENHOUSE TECHNOLOGIES
Controlled Preparation and Distribution of Nutrient Solution
A correct recipe alone is not enough. Stock tanks, dosing equipment, EC and pH sensors and irrigation zones must work together. Fertigation prepares the nutrient solution; irrigation automation distributes it to the assigned zones. Alarms and operator oversight keep both roles traceable.
- Modular DesignSuitable for projects of every scale
- Integrated SystemsWorking together in harmony
- Long-lasting StructureReliable and sustainable
What’s in the System?
Fertigation System: Controlled nutrient preparation and dosing.
How Is a Fertigation System Selected?
System architecture is selected by evaluating production data and the technical requirements of recipes supplied by the operation.
- Crop
- Growth stages affect the recipe and program structure to be applied.
- Cultivation method
- Soil, substrate and hydroponic production require different preparation and control arrangements.
- Nutrient recipes
- Targets supplied by the operation or specialist guide tank and dosing architecture.
- Water quality and starting EC/pH
- Source conditions affect the measurement and control approach.
- Irrigation flow and number of zones
- Flow and segmentation define mixing operation and recipe transitions.
- Number of stock tanks
- Chemical compatibility and concentrates determine separation requirements.
- Dosing accuracy and measurement
- Control expectations guide injection equipment and sensor selection.
- Automation, alarms and logging
- Monitored values, warnings and reporting depth are defined for the operator.
Greenhouse Fertigation Solutions
No option fits every project. Selection depends on cultivation method, capacity, water quality, recipe structure and control needs.
A/B stock-tank fertigation systems
Separate storage and suction arrangements are planned for incompatible concentrates.
Dosing-pump nutrient injection
Dosing pumps manage nutrient lines for the required flow and control range.
Venturi-based injection
Venturi is considered only when hydraulic conditions and control needs are suitable.
EC and pH controlled mixing units
Sensors and controls compare measured solution values with supplied targets.
Hydroponic nutrient preparation
Preparation, application and any return-water strategy are coordinated with the production system.
Recipe and zone-based automation
Defined recipes, schedules and zone assignments are managed through central control.
Why Is Fertigation Automation Important?
Repeatable dosing control
It supports applying defined recipes through consistent control steps.
EC and pH monitoring
Operators can follow measured solution values during operation.
Zone and recipe management
Programs can be assigned to different production areas.
Alarms, records and oversight
Out-of-range conditions become visible and operating history can be reviewed.
Accurate Measurement, Calibration and Material Compatibility
Safe, sustainable operation depends on accurate measurement, compatible wetted components and practical access for inspection, cleaning and maintenance.
- Probe checks and calibration
- EC and pH probes require regular inspection and calibration under manufacturer requirements.
- Material compatibility
- Tanks, pumps, seals and pipes must be selected for the chemicals used through specialist assessment.
- Stock-solution separation
- A and B solutions remain separate where incompatibility and precipitation risks require it.
- Safe operation and access
- Acid or pH-control lines require suitable equipment, procedures and maintenance access.
Frequently Asked Questions About Greenhouse Fertigation
What is a fertigation system?
It is a technical system that doses plant nutrients into irrigation water under defined recipe and control values.
How does greenhouse fertigation automation work?
Injection equipment transfers stock solutions into mixing water while sensors and controls monitor supplied targets.
Why are EC and pH controls important?
They help compare the prepared solution with defined targets and make conditions visible to the operator.
Why are A and B fertilizer tanks kept separate?
They separate concentrated components that could react and form precipitates if combined.
Can fertigation be added to an existing irrigation system?
Integration options can be identified after flow, pressure, zones, controls and material compatibility are reviewed.
Can fertigation be used in hydroponic production?
Yes. Preparation, measurement and any return-water strategy are designed for the hydroponic arrangement.
Can different recipes be applied to different irrigation zones?
Separate recipes or schedules can be assigned when the control and process architecture supports them.
What information is needed for a fertigation project?
Crop, cultivation method, water analysis, flow, zones, recipe structure, existing equipment and control needs are required.
