What is NDVI in agriculture?

NDVI (Normalized Difference Vegetation Index) is an index calculated from multispectral images captured by drone. It measures the leaf vigour of crops by comparing red and near-infrared wavelengths. A high NDVI indicates dense, healthy vegetation; a low NDVI reveals stress or an anomaly to be treated.

How does AI weed detection work?

The drone flies over the plot and captures ultra-high-resolution images. Our artificial intelligence analyses each zone, identifies and locates weeds, then generates a weed presence map. The farmer can thus target their weeding and significantly reduce their herbicide consumption.

What is NDWI and what is it used for?

NDWI (Normalized Difference Water Index) is a multispectral index that detects the water content of plants and soils. It allows water stress zones to be identified in a plot even before wilting symptoms are visible to the naked eye, so that irrigation can be adapted accurately and economically.

What does agricultural drone diagnostics actually replace?

Drone diagnostics replace partial ground observations and systematic treatments applied to an entire plot. By accurately mapping the real state of the crops — weeds, vigour, water stress — it enables targeted interventions that reduce costs, inputs, and environmental impact.

DRONE DIAGNOSTICS & AI

DRONE AND AI DIAGNOSTICS: A 360° VISION OF YOUR CROPS FOR PRECISION AGRICULTURE

AGREEGO offers a multidimensional analysis of your plots. By combining drone technology, multispectral sensors and artificial intelligence, we transform aerial imagery into actionable data. Optimise every step of your technical itinerary through proactive, sustainable and profitable management.

WHY CHOOSE DRONE DIAGNOSTICS?

Aerial drone detection offers advantages that no conventional observation can match. It allows you to cover vast areas in record time while identifying issues invisible to the naked eye through spectral analysis.

OUR DRONE & AI DIAGNOSTICS: WEED DETECTION, NDVI ANALYSIS AND NDWI MAPPING

AI Weed Detection

Our AI software from AGREEGO LAB ensures dual verification (shape + colour) for maximum reliability. Precisely identify species and infested zones for targeted interventions.

Without AI detectionLess effective

Start of cycle: without precise identification and adequate treatment, a wide diversity of weeds can develop.

Mid-cycle: generalised interventions without distinction of weeds present can reduce treatment efficacy.

End of cycle: uncontrolled weeds cause additional problems at harvest and for crop valorisation.

AI weed detection Recommended

Start of cycle: weeds are precisely detected by AI through onboard sensors.

Mid-cycle: infested zones being identified and located, treatment is thus more effective.

End of cycle: weeds have been better controlled, harvest is cleaner and yield is preserved.

Leaf Vigour (NDVI) — A Global Monitoring Tool

The NDVI diagnostic is essential for all your crops (maize, wheat, rapeseed, potato, etc.). It measures biomass and photosynthetic activity in your plots. It is the ideal tool for:

Modulating your nitrogen inputs according to the real needs of each zone.
Monitoring growth and early identification of disease or deficiency hotspots.
Optimising your yields by intervening at the right place, at the right time.

Water Stress (NDWI)

Anticipate the water needs of your crops before signs of wilting become visible. The water stress diagnostic allows you to manage your irrigation with precision and secure your yields during drought periods. For real-time monitoring, we also install permanent connected probes. This data, combined with weather forecasts and soil water content, provides personalised irrigation advice, directly accessible on our AGREEGO Cloud platform.
