Precision agriculture

Research:

Agricultural production inputs such as fertilizers and herbicides ensure our food security but also adversely affect our environment and add significantly to the production costs. This research helps developing remote sensing tools and techniques that allow farmers to reduce their fertilizer inputs while maintaining their yields.
