How it works
Up to 10 measurements per 5 hectares
Clip the leaf with the device and press the button.
Data are sent automatically
Measurements go straight to your portal. Nothing to copy by hand or send to a laboratory.
Top up the sprayer
You see which nutrient is missing and add it to the next spraying, before the deficiency hurts the yield.
Short press – click; long press – hold for ~1 s. Glowing buttons are the ones you can press now.

The device is on. Before measuring it must be calibrated twice (in any order): W – insert the white plates and press W (white calibration); B – without the plates press B (black calibration, the inside of the clip is black). Only after both calibrations is it clear whether the device will measure accurately (e.g. whether the measuring tip is dirty). Then hold P for ~1 s to enter the measurement information and measure.

After the first measurements – a map for every nutrient
After analysing the measurements, we provide a field map divided by the probability of each nutrient's deficiency. Later measurements are planned from it: we recommend measuring at the specific spots where the probability of deficiency is highest.
Lighter colour – higher probability of deficiency (0–1). Real portal screens from a farm in Lithuania.
Tech specs
Already used on farms in Lithuania and Latvia and at the University of Tartu in Estonia. On one Lithuanian farm, fertilising according to the measurements raised wheat yield from 7–8 to 9 t/ha over two seasons.

Seasonal rental
Want to try it in your own fields first? Rent it for one season. If you buy later, the rental fee is credited.
RentWhen will it pay off?

of extra yield is enough to pay back the first year (€2,200).
Calculated with a wheat price of €200/t.
Frequently asked questions
How is this different from a soil test?
A soil test shows what is in the ground. SmartAgrometer shows what the plant has actually taken up and what it is missing now – while you can still add it to the sprayer.
How accurate is it?
In more than 85% of cases the results agree with laboratory chemical plant analyses. The scientific basis is published in the peer-reviewed journal Plants (2026).
How long do the measurements take?
The first time, 500–1000 ha are measured thoroughly in a day, even in awkward fields. Once the fields have been measured and analysed, later measurements take several times less: a few typical spots are enough, as fields on one farm are usually similar.
Which crops is it for?
Winter and spring wheat, barley and maize.
What do I do with the result?
The portal shows which nutrient is limiting growth and recommends what to add to the sprayer.
