Abstract
Even in temperate climate areas like Belgium, irrigation rates should be optimized in space and time to economize on water use. To study whether this can be achieved using unmanned aerial vehicle (UAV) imagery combined with real-time soil moisture data, a 7.4 ha 'Conference' pear (Pyrus communis) orchard was monitored with multispectral cameras during three consecutive years from 2018 onwards. Analysis of the normalized difference red edge (NDRE) derived from UAV imagery revealed inhomogeneities in the orchard's irrigation system. In 2019 and 2020, this information was combined with real-time soil moisture data to steer variable rate irrigation, resulting in water use reductions up to 811 m3/ha without impairing fruit yield, yet improving fruit quality.
