D.I.S places hydro-retaining material under crop roots at a prescribed dose and depth, with tools we design and build, then measures what the crop does with the water. Every mission is a field experiment with a control.
Each mission follows the same five steps. The figure redraws as you scroll, the way a protocol is followed at the bench.
The 3D figure needs WebGL. Each step is described alongside.
The figure opens on a finished placement: crystals banded under the roots, water held and released. Scroll to see how a mission gets there.
Soil texture and horizons, crop and rooting depth, climate, water source and irrigation system. The field is profiled before a prescription is written.
ALGO D.I.S sets dose, depth and placement for the crop and soil, and the irrigation scenario that goes with them. Issued per mission; the calculation logic stays confidential.
An injection tine places the material in a band under the active roots at the prescribed depth, per linear metre of row or per tree.
Irrigation water is absorbed by the crystals and released to the roots as the soil dries. Through the season we record volumes applied, soil moisture and growth against an untreated control.
Results against the control, with the method, the measurement and its limits stated. Every report adds samples to the field record behind ALGO D.I.S.
ALGO D.I.S is a proprietary algorithm developed by D.I.S. Choose a crop, soil and irrigation system: the diagram shows what a prescription covers and the nearest result in the field record. Output values are issued per mission.
Our injection tools are unique: D.I.S designs and builds them itself. Hydro-retaining material spread on the surface does little; these tools place it under the roots at a set depth, so the protocol repeats at field scale. Scroll to separate the parts.
Row crop injection machine
For seeded and planted field crops: maize, cotton, potato, alfalfa. Places a continuous band under the row.
| No. | Part | Function |
|---|---|---|
| 1 | Hopper | Holds the crystals |
| 2 | Metering unit | Sets dose per linear metre |
| 3 | Frame and hitch | Carries the tool bar |
| 4 | Delivery lines | Feed each tine |
| 5 | Injection tines | Place material at depth |
| 6 | Depth wheel | Holds working depth |
Tree injection machine
For orchards and palms: date palm, citrus, olive. Injects around each tree, under the active roots, without lifting the soil.
| No. | Part | Function |
|---|---|---|
| 1 | Carrier | Moves between trees |
| 2 | Tank | Holds the material |
| 3 | Pump and meter | Sets dose per tree |
| 4 | Articulated arm | Positions the lance |
| 5 | Injection lance | Places material at depth |
Landscape injection machine
Designed and developed by Yann and Sylvain Le Coz for Aquaject, the French company that owns it. PENDOUR treats every non-agricultural grassed surface in landscaping, from golf courses to sports fields and parks, and injects different types of hydro-retaining materials. Depth and quantity are set with ALGO D.I.S.
Purpose-built tools for trees, seeded crops and planted crops, supplied or deployed with a mission.
Design adaptation, specifications and industrialisation support for partners building the tools locally.
Local teams trained to calibrate, deploy and monitor, so the protocol holds when the crew changes.
Trials led by the D.I.S founders from 2020 to 2025 with a hydro-retaining material, before D.I.S was founded. Each tile gives crop, place, year, how it was measured, its source and its limits. Highlighted text is a stated limit.
ICBA confirmed the validity of the results of the trials it ran, and disclaimed other conditions.
82% less irrigation water over 294 days, with +20% average yield at 1,000 g per tree.
ICBA, Dubai · 2020–2021 · sand, subsurface drip · flow meters
Against a schedule with 25% safety and 25% leaching allowances. Yield after an age allowance the control does not match.
With irrigation cut to a 50% regime, fresh biomass loss was limited to 26–35%, against 55% untreated.
ICBA, Dubai · 2022–2023 · 36 plots · 38.7% less water over 12 months
No benefit at 100% irrigation.
48% and 38.5% less water. Yield from 18% below to 13% above the fully irrigated control, against 36–48% losses without.
ICBA, Dubai · 2022–2023 · open field and greenhouse
Result depends on tube size. Replication not stated.
Without replication. The partner farm supplied the measurement; the company wrote the report.
39% less irrigation water (864 to 528 mm) and +17.1% yield at 74 kg/ha.
Konya, Türkiye · 2025 · TİGEM farm · clay, drip · weighbridge
Single season. 0% and +8.7% at lower doses.
Irrigation reduced 36–37% on the treated sectors, with about +13% yield at 62.5 kg/ha.
Bala, Ankara, Türkiye · 2025 · clay, sprinkler, saline water
Yield by the partner's visual estimate. Monitoring failed.
Under a 50% water deficit with the same irrigation: premium calibres 38.2% of fruit against 21.2%; 12.5 against 10.7 °Brix.
Marrakech, Morocco · 2025 · ISO 17025 laboratory for quality
No yield or economic figure. One row per regime, 20 trees.
With the same irrigation on both areas: 2,529 to 4,882 kg/ha.
Hatay, Türkiye · 2025 · clay, flood · gin weighing certificates
Irrigation volume not measured. A recovery toward the regional normal, not a surplus above it.
Each mission sends paired samples, treated and control, into one record. What exists today is drawn solid. What is planned is drawn dashed.
Led by Yann Le Coz, the solution is one of six finalists of the Al Miyah Challenge for Agriculture (announced 30 April 2026). Testing at Silal Innovation Oasis, Al Ain, is in progress, outcome expected end of 2026. A recognition, not a validation of any figure.

Two brothers. One writes the prescription, the other builds the machine that applies it.
Founder. Seventeen years as a French Air Force officer and fighter pilot, then six years of field work on hydro-retaining systems in the UAE, Türkiye and Morocco. Author of ALGO D.I.S, the proprietary prescription algorithm: dose, depth, irrigation strategy, and agronomic and economic forecasts.
Co-founder. Former chief technology officer in hydro-retaining agritech. Designer of the proprietary injection tools for trees, field crops and turf, and of their mechanised deployment.
For governments, agribusinesses, material producers and research partners. Describe the field and we reply with the next step. A first season starts as a small paid trial with an untreated control.
