Both SMART Fertigation and Green-DROP are built around the same core capability: delivering different irrigation rates to different zones within a single field pass.
HYDRO-AIR INTERNATIONAL IRRIGATION SYSTEMS GMBH
German SME making variable-rate irrigation and fertigation hardware for pivot and linear field machines, EU-validated through SME Instrument Phase 1 and Phase 2.
Their core work
Hydro-Air develops precision irrigation and fertigation hardware for large-scale agricultural fields, with a specific focus on subarea-specific control — meaning the system delivers water and fertilizer at different rates across different zones of the same field rather than treating the whole area uniformly. Their core product line targets pivot and linear irrigation machines, the dominant equipment type in European and export-market row-crop farming. They progressed from a feasibility-stage concept under the EU SME Instrument into a fully funded Phase 2 development project, indicating they moved from prototype to a market-ready system within the H2020 programme.
What they specialise in
SMART Fertigation explicitly targets combined irrigation and fertilization delivery via pivot and linear machines.
SMART Fertigation names pivot and linear systems as the specific hardware platform for their technology.
Green-DROP describes a 'precise subarea specific irrigation and fertilization system', positioning the company squarely in precision ag hardware.
How they've shifted over time
Hydro-Air's trajectory within H2020 is a textbook SME Instrument scale-up: a 2016 Phase 1 feasibility study (€50,000) on pivot and linear fertigation was followed in 2018 by a Phase 2 full development grant nearly twenty times larger (€968,966), suggesting the Phase 1 validated both the technical concept and the market case. The shift from the SMART Fertigation framing — which emphasised the fertigation delivery mechanism — to the Green-DROP framing, which emphasises precision and resource efficiency, may reflect a deliberate pivot in market messaging toward sustainability and input reduction rather than pure machinery innovation. No keyword data is available to confirm finer shifts in technical focus, so this reading relies on project titles and descriptions alone.
The company appears to be scaling a single well-defined product — variable-rate irrigation for large field machines — toward commercial deployment, making them a potential technology supplier rather than an ongoing R&D partner.
How they like to work
Hydro-Air coordinated both H2020 projects with no recorded consortium partners, which is characteristic of companies using the SME Instrument as a product development grant rather than a collaborative research vehicle. This means they are self-reliant on their own IP and engineering capacity, and are unlikely to be seeking joint research relationships — but could be interesting as a technology provider or subcontractor in a larger precision agriculture consortium. Anyone working with them should expect a company-to-company commercial dynamic rather than an open academic collaboration.
Based on available H2020 data, Hydro-Air has no recorded consortium partners and has not collaborated with organisations in other countries through the programme. Their network footprint is essentially zero in terms of formal R&D partnerships.
What sets them apart
Hydro-Air is a rare example of a German hardware SME that has built and EU-validated a complete variable-rate fertigation solution specifically for pivot and linear irrigation machines — a niche most agri-tech companies have not addressed at the hardware integration level. Their successful Phase 1 → Phase 2 progression under competitive EU evaluation gives independent credibility to both the technology and the business case. For a consortium needing a demonstrable field-scale precision irrigation component, they represent a potentially deployment-ready industrial partner rather than a research organisation still working at lab scale.
Highlights from their portfolio
- Green-DROPAt nearly €1 million in EC funding, this Phase 2 SME Instrument grant represents a full product development investment and is the clearest signal that Hydro-Air's core technology cleared EU-level commercial viability assessment.
- SMART FertigationThe Phase 1 feasibility project established the technical and market foundation for Green-DROP, making it the origin point of the company's EU-funded product line.
