Thermal infrared remote sensing (TIRS) has already shown strong potential for detecting water stress in crops. Although TIRS sensors installed on drones could replace those on satellites, they are not yet widely used.
The aim of this project was to study the relationship between thermal imaging data collected by drone and agrometerological indicators of water stress in potato crops to develop water stress indicators that can be measured by drone.
These indicators can be used to optimize irrigation in potato crops by enabling growers to apply the right amounts of water at the right times in the right places.
Optimal water management
With precision farming, farmers can provide the right amount of irrigation at the right times and in the right places.

By enhancing our understanding: 1) of the nitrogen supply dynamics associated with the use of mixed green and farmyard manure applications, and 2) of the timeline of nitrogen uptake by garlic; we hope to fine-tune fertilization strategies so they meet the needs of garlic crops, while minimizing phosphorus accumulation and nitrogen leaching.

The project consisted of manufacturing and testing a portable rain simulator to estimate, under various conditions, what proportion of irrigation water a crop is able to use.
