The development of optical devices allowing the remote monitoring at
sub-field scale of traits specifically linked to molecular, biochemical or
physiological consequences of scarcity or excess, of specific essential ele-
ments other than nitrogen, is surely a challenge for future research. Following
on from the
spectranomic
approach developed by Asner and Martin (
2008
)as
the application of metabolomics for the assessment of biochemical traits at a
landscape scale, Brunetti et al. (
2013
) suggest an airborne hyperspectral
analysis whereby changes in absorbance and reflectance patterns of specific
chemical compounds within leaves could further improve detection of bio-
chemical phenotypes across a relatively large scale. A combination of these
approaches could define exciting new frontiers for the fine-tuning of contin-
uous and non-destructive methods of monitoring plant nutritional status in the
field. In the next years, whereby multidisciplinary studies, efforts have to be
planned to actually translate in field the knowledge accumulated that seem to
promise interesting deliverables.
