Drip network
The methodology we apply in Russia rests on an accumulated international portfolio — a Geoflow Türkiye network of 50+ projects over 2,000+ hectares, three decades of commercial subsurface drip practice anchored by Nano-ROOTGUARD® root-intrusion protection.
Aegean.
Tunisia. Iran.
Winery and table-grape estates. Subsurface drip removes berry-split and equalises sugar across slope rows.
Commercial orchards. Subsurface delivery at 40–60 cm serves dense mature root systems.
150 ha in Türkiye (3) and 260 ha in Tunisia (2). Subsurface improves fruit fill and oil quality.
Documented +29% grain versus rainfed at the same varieties — a striking row-crop result.
Subsurface delivery removes evaporation losses on an open summer cotton field.
Subsurface delivery plus fertigation raises Brix and reduces weed pressure.
Deep-rooted crop; subsurface delivery serves the 40–80 cm root mass.
Four layers of evidence.
Project methodology
Burial depth, lateral spacing, emitter flow, filtration, drainage — accumulated across 50+ projects and 2,000+ ha, adapted to Russian chernozem.
Emitter technology
Nano-ROOTGUARD® with 10-year warranty; ASSIF / VERED anti-siphon; pressure compensation for long laterals and slopes.
Manufacturer warranty
50 years on GEO-PVCo pipe, 10 years on GeoFlow drip — applied to a Russian project on the same terms as a Turkish or Tunisian one.
EAEU documentation
Geoflow Türkiye certificates converted into TR TS format; documentation prepared for state-support reclamation programs.
Terra-Zenith launched its first pilot projects in Russia in the 2026 season — Krasnodar Krai, Stavropol and Voronezh Oblast. Crops: grape (Taman), sunflower (Stavropol), sugar beet (Voronezh), winter wheat (Rostov).
First-season results (yield, sugar content, gluten, economics) publish in the journal as farms provide formal consent for disclosure. Until then we provide aggregated Geoflow Türkiye network data as the evidence base — more honest than claiming results that do not yet exist.
Why doesn't Terra-Zenith publish reference customer names?
Commercial confidentiality is standard practice. Names, locations and contracts are disclosed only under NDA to qualified prospective customers. Network-wide aggregated metrics are publicly available.
Do Turkish project results apply to Russian conditions?
Partly. Project methodology transfers directly with adaptation to Russian soils and climate. Specific yield numbers do not; the first Russian pilot projects in 2026 will deliver real data, published subject to farm consent.
Which certificates does Geoflow Türkiye hold?
ISO 9001; products conform to ISO 16422 and EN 17176-2; factory declarations of conformity to country-specific standards (TR TS for the EAEU). Certificate copies are included in the project package.
