Lab-grade leaf nutrient analysis,
in the field, in minutes.
Rest the Metiris handheld sensor on a leaf and read N, P, K and micronutrients straight from the plant — non-destructive, with no waiting on the lab and no per-sample fee.
- Validated on 700+ field plots — ~81% agreement with the lab.
- Shipping globally
In the field with growers & research partners
The lab can't keep up with the field.
Nutrient demand shifts week to week with light, growth stage and crop load. But the feedback loop most growers rely on still runs through a laboratory: clip the leaves, ship them, and wait.
- 3–21 days of waiting. By the time a result lands, the plant has already moved on.
- €25–200+ per sample. Cost limits how often you can measure — so you don't.
- One number, a whole field. A few composite samples can't map variation across plots.
The old feedback loop
Decisions made on stale, sparse data — a step behind the crop.
Metiris closes this loop to a single visit.
Scan the plant. Read the result. Act the same visit.
No sampling kit, no shipping, no waiting. Three steps, on the spot.
Scan on the plant
Rest the handheld sensor on a leaf. A built-in spectrometer reads how light is absorbed, transmitted and reflected — fully non-destructive.
Models do the work
Deep-learning models trained on chemically validated samples translate the spectral fingerprint into nutrient concentrations, tuned to your crop and growth stage.
Act the same visit
Get nutrient status and fertiliser guidance on a clean web dashboard — so you can tune the mix before the next irrigation, not next week.
Right amount, right place, right time.
A reading whenever you want one turns nutrient management from a guess into a routine.
Tighter fertigation control
Read nutrients directly from the canopy and correct the solution on the same visit — closing the gap between a weekly lab result and the mix you actually run.
Measure as often as you want
With no per-sample lab fee, scan across rows, blocks and growth stages to map variation instead of trusting one composite sample.
Catch stress before symptoms
Spectral signatures shift before a deficiency is visible, buying you time to intervene while the fix is still cheap.
Less waste, cleaner crops
The right amount at the right time trims input cost and helps you meet retailer and regulatory limits on residues and nutrient loading.
Everything the lab gives you — minus the wait and the bill.
Same job, validated against laboratory references. Done in your own field.
Validation: across 700+ Champagne vineyard plots, Metiris nutrient readings reached ~81% agreement with laboratory measurements — the same platform now extends to greenhouse, orchard and open-field crops.
One sensor, across your crops.
Calibrated by crop and growth stage, with paid and pilot deployments running today.
Vineyards
Champagne & still wine — steer vigour, quality and VDC sustainability targets, plot by plot.
Greenhouse & CEA
Tomato, cucumber, pepper and leafy greens — tighten fertigation week to week.
Orchards
Track tree nutrition through the season and right-size inputs before harvest.
Open field
Map variation across blocks and apply nutrients where the crop actually needs them.
Prove it in your own crop.
We're onboarding a small group of growers as pilot partners. A pilot puts the sensor in your field against your own lab references — so you judge the value on your numbers, not ours.
- A Metiris handheld sensor and web dashboard for the season
- Side-by-side benchmarking against your existing lab results
- Crop- and stage-specific calibration support from our agronomy team
- A direct line to the founders — your feedback shapes the product
What we ask in return
Pilots are built to be a fair, low-risk trade. We put the hardware, the dashboard and our agronomists on your crop for the season.
A complementary founding team.
Metiris is a spin-off of Ghent University, born from the plant-phenotyping and remote-sensing research groups of Prof. Kris Audenaert and Prof. Wouter Maes. The three founders pair deep agronomy and photonics expertise with two decades of hardware, software and product experience — every skill needed to scale this from a sensor into the trusted data layer for agronomy.
Inventor of Metiris' core sensing technology and a PhD in Bioengineering. Leads the science and the vision behind reading nutrition straight from the leaf.
Ten years as a sales lead, product manager and head of product. Turns the technology into something growers actually want to pick up and use.
Twenty years in photonics, hardware and software development and production. A practiced co-founder and CTO who builds the device that goes in your hand.
"We built Metiris so a grower can trust what's happening in the crop today — not what a lab measured three weeks ago. Put it on your plants and judge it on your own numbers."— Louis Daniels, Founder & inventor
