1. Introducon
1.1. Nutriscope™: A lab and Crop Advisor in Your Pocket
Nutriscope is a groundbreaking scanner designed for farmers and agricultural professionals, providing real-me insights into
plant stress, health, and overall vitality. By leveraging advanced photonics and arcial intelligence, Nutriscope measures a
broad range of parameters—once obtainable only through expensive wet labs or complex eld equipment—with just a single
click.
Measuring plant health and stress: The device captures crical plant health and stress metrics using (pH, Redox, approach) On
plant health, Nutriscope delivers a detailed nutrient analysis by quanfying essenal components such as total nitrogen,
ammonium, phosphorus, potassium, iron, sulfur, SiO₂, manganese, magnesium, calcium, boron, and chloride—data that is vital
for opmizing ferlizaon strategies and maximizing yield. On plan stress Nutricope ‘s measurements oer a comprehensive
view of plant condion, enabling the calculaon of a stress index according to bioelectronic approach measuring the
intensicaon of the living approach important when looking at agroecology pracces.
Your crop best ally: Beyond its measurement capabilies, Nutriscope is connuously enhancing its plaorm
(hps://portail.senseen.io/en) and app (Senseen Pencil) to unlock even more value for the farmer. The plaorm securely stores
your eld data and will soon integrate third-party sources, such as weather and satellite informaon, to oer broader
perspecves that support your own analyses. Addionally, an upcoming eld note feature will allow you to record geolocated
notes directly from your phone, seamlessly linking your observaons with precise eld data.
Our rst “redox” decision support system (DSS) is already deployed for select crops. This preliminary version will interpret scan
results, providing recommendaons for further diagnosc intervenons—such as checking the root system—or oering
targeted advice to opmize crop management. Our commitment to simplifying science will connue as we work toward
developing a Large Language Model (LLM) that integrates best pracces in crop management for something likes “ a crop
advisor in the pocket”.
1.2. Agroecology at Your Own Pace
Nutriscope™ adapts to your journey toward sustainable agriculture, whether you're taking your rst steps or enhancing exisng
pracces. At the heart of sustainable agriculture lies agroecology, a science-based approach that leverages natural processes
to build resilient farming systems, improve soil health, and enhance plant vitality. A key component of this approach is
understanding the biochemical interacons within plants—specically, the relaonship between pH and redox potenal, which
serves as a fundamental indicator of plant health. More scienc informaon at

Reference framework: the pH/Redox cross: Nutriscope brings this
concept to life with its innovave pH/Redox Cross measurement, a
model developed by Olivier Husson
1
based on over three decades of
research into redox regulaon in biological systems. The pH/Redox
Cross provides a framework to assess how plants respond to their
environment, helping farmers idenfy whether their crops are thriving,
experiencing stress, or struggling to maintain balance due to external
pressures.
• At the core of this model lies the Green Zone, where plants
funcon at their best, focusing energy on growth, nutrient
absorpon, and natural defenses. In this opmal state, crops
are resilient, producve, and contribute to maintaining soil
health. However, when exposed to stressors—such as
drought, nutrient imbalances, or pest infestaons—plants
shi into the Orange Zone, where they redirect energy to migate damage, leading to slower growth and increased
vulnerability to disease.

Husson, O., Sarthou, JP., Bousset, L. et al. Soil and plant health in relation to dynamic sustainment of Eh and pH
homeostasis: A review. Plant Soil 466, 391–447 (2021). https://doi.org/10.1007/s11104-021-05047-z
• If stress connues to escalate, the plant may enter the Red Zone, where excessive oxidaon disrupts its internal
balance. This can be exacerbated by human intervenons, such as the overuse of pescides, which increase oxidave
stress. In this state, plants can expend up to 80% of their energy on self-repair instead of growth, weakening their
resilience and reducing overall yield.
Our stress index: To help farmers keep their crops in the Green Zone, Nutriscope provides a stress index derived from real-me
pH and Redox measurements. By connuously monitoring these key indicators, farmers can detect early signs of stress, adjust
management pracces accordingly, and ensure crops remain in an opmal state for growth and producvity. With Nutriscope,
agroecological principles are not just a philosophy but a praccal, data-driven approach to achieving healthier crops, richer
soils, and a more sustainable future.

as they align with Nutriscope’s original calibraon, ensuring higher accuracy and reliability.
• Single Measurement Scan: This mode provides results from a single scan, but it is not recommended as it may be
less accurate due to natural variability in plant samples.
By default, the app is set to Group Measurement mode with ve scans. To adjust this number, tap the Sengs icon (gear icon)
on the top right hand corner and update the value as needed.
For best pracces on sampling methods, refer to the next secon of this document.
o If you focus on measurement parameters such as pH and Redox, we recommend choosing a seng of 5
scans minimum. Look at various protocols on our website
o If you focus on nutrients, you need to set group of 15 scans to match as best as possible the method used
by Senseen during calibraon.
o If you are looking for addional guidance, we recommend consulng the best pracces for sampling
developed by our partner Novacrops here:
▪ English
Step 8: Scan
• Name your scan (oponal): Fill the “Tag” eld to give a name to your scan
• Prepare sample: Select the leaf you want to analyze and place it in the “leaf clipper”. Close the clip and make sure
outside light cannot hinder the quality of the scan.
• Launch scan: Press “Take a measurement”. Wait for few seconds to access scan results.
• If you selected “Group measurement” repeat these steps as needed.
Best Pracces for Accurate Scanning
• Consistency: Repeat your measurement process as consistently as possible (e.g., selecng the same leaves,
measuring at the same me of day). This will provide a clearer understanding of the trends aecng your crop.
• Sensive Measurements: If measuring sensive parameters like Redox, perform measurements early in the
morning (before 9 AM) as photosynthesis can introduce signicant variaons in your readings.
• Sample Placement: Ensure the scanner is in full contact with the sample surface and prevent any external light
interference for precise measurements.
• Cleanliness: Wipe the scanner sensor with a so, lint-free cloth aer each use to prevent cross-contaminaon.
• Environment: Avoid scanning in extreme weather condions or direct sunlight, as these may aect sensor
performance.
Step 9: Analyze
Press “Save Scan” to make sure, your data is stored on the plaorm or “Delete scan” if you are not sased.
With your subscripon, all measurements are automacally saved in the cloud under the product's prole, and will also be
accessible on the Senseen’s plaorm and mobile App. The results are visualized in graphs and charts for easy interpretaon.
You can also compare them with historical data to idenfy trends or anomalies.
Once the scan is complete, the app will display the results, including key metrics such as:
o Stress parameters such PH , Redox and EC levels: Indicators of soil or crop health.
Together with Brix levels: Measure of sugar content in fruits or vegetables.
Chlorophyl can also be provided

4. Sampling Best Pracces
To maximize the accuracy and consistency of your Nutriscope™ measurements, follow our measurement protocols available
on our website in the “Scan” secon, as well as the recommended best pracces:
Use 15 scans (group measurement) when focusing on nutrient analysis for
the most reliable data.
Use minimum 5 scans (group measurement) when assessing plant stress
(e.g., Redox measurements).
Maintain consistency in your sampling pracces to track trends eecvely
over me and improve decision-making.
Sample early in the morning, before 9 AM to minimize variability caused by
photosynthesis
You can Sample young and old leaves separately if you want to analyse
nutrient movements.
Avoid sampling the leaf peole (leaf stalk) as it may aect measurement
consistency.
Do not sample from areas such as side paths or headlands, as these
locaons may not be representave of the crop.
Separate decient leaves from healthy leaves to beer understand stress
condions and nutrient imbalances.
Ensure samples are free from dew, moisture, or dirt to prevent
contaminaon and inaccurate readings.
Collect samples before foliar spray applicaon or wait at least one week

8. Theory of operaons
8.1. How does Nutriscope works
Nutriscope™ works by shining light onto a plant and measuring how much is absorbed, reected, or transmied. Just like a
ngerprint, each plant compound (chlorophyll, nutrients, stress markers) interacts with light in a unique way. Nutriscope™
analyzes these interacons to give you real-me crop health insights.
Nutriscope™ operates using a three-step process that allows for real-me, non-invasive crop health analysis:
Emission of Light onto the Plant: The device emits light from
a set of LEDs at specic UV, visible, and near-infrared (NIR)
wavelengths. These wavelengths are carefully selected to
target key biochemical properes of the plant, such as
chlorophyll content, nutrient levels, and stress markers.
Recepon of Refracted Light: As light interacts with plant
ssue, certain wavelengths are absorbed, while others are
reected. Nutriscope™’s opcal sensor precisely captures the
intensity of reected light across dierent wavelengths,
allowing for detailed spectral analysis.
Calculaon of the Absorpon Curve: Nutriscope™ determines
the absorpon curve by analyzing the dierence between
emied and received light. This curve serves as a unique
spectral ngerprint, revealing the plant's chemical
composion. Disnct peaks and valleys in the absorpon
curve—or complex paerns detected through AI-powered
analysis—indicate how specic plant compounds, such as
chlorophyll and nutrients, interact with light. By decoding
these paerns, Nutriscope™ quanes key plant health
parameters, delivering aconable insights to opmize crop
management.
The Nutriscope™ captures the absorpon curve, which
represents how dierent wavelengths interact with the
plant’s ssues. The absorpon curve is like a ngerprint
for each element or compound in a plant—it uniquely
idenes how dierent substances interact with light.
Just as every person has a unique ngerprint, chlorophyll
a, chlorophyll b, and carotenoids each have disnct
absorpon paerns at specic wavelengths (see
diagram). For example, chlorophyll a absorbs the most
light in the blue (~430 nm) and red (~665 nm) regions,
while chlorophyll b peaks around 455 nm and 640 nm,
and carotenoids absorb strongly in the blue range (~450
nm) but reect yellow and red light—which is why leaves
turn yellow in the fall. By analyzing these unique
absorpon paerns, Nutriscope™ can detect nutrient levels, stress factors, and overall plant health, giving farmers precise,
real-me insights.
8.2. How is Nutriscope calibrated?
To ensure accurate measurements, Nutriscope™ underwent a rigorous calibraon process using real-world plant samples and
advanced machine learning algorithms.
Data Collecon: Measuring the Absorpon Curve
For each crop type and measurement parameter (e.g., chlorophyll, pH, Brix levels, nutrients), we rst capture an absorpon
curve from a group of leaves—this forms a single sample. The same sample is then analyzed using independent reference
methods, such as wet lab chemical analysis or high-precision in-eld sensors.
Building the Calibraon Model
To create a robust model, we collect a few hundred samples for each crop type. 80% of the samples are used to train the
calibraon model. The remaining 20% are reserved for validaon—a "blind test" to check accuracy.
Machine Learning Calibraon
Using machine learning algorithms, Nutriscope™ learns to correlate its absorpon curves with real-world lab measurements.
The process involves:
• Idenfying paerns in the absorpon spectra across dierent crop condions.
• Mapping spectral data to actual nutrient concentraons, Brix levels, or other parameters.
• Rening the model by minimizing errors between Nutriscope™ predicons and lab results.
Accuracy Validaon
Once trained, we test the model using the
20% validaon samples that were not part of
the training set. Nutriscope™ predicts the
values for these samples, and we compare
them to their independent lab-measured
values (see example on the gure). The
dierence between Nutriscope™’s
predicons and the actual reference values
helps us esmate the accuracy and reliability
of the device.
Nutriscope™ measurements are based on
spectral analysis and machine learning.
Accuracy depends on crop type, environmental condions, and calibraon data. Nutriscope™ is connuously improving its
calibraon models. As we collect more data and rene our machine learning algorithms, we aim to increase accuracy across
all parameters. Updates and improvements will be regularly integrated into our system to ensure that users receive the most
reliable and aconable insights possible.
