Marie van Maarschalkerweerd, Søren Husted
2015 Frontiers in Plant Science  
At the same time, sub-optimal or excessive use of fertilizers leads to severe environmental damage in areas of intensive crop production.  ...  Spectroscopic techniques considered having major potential for plant mineral analysis, such as chlorophyll a fluorescence, X-ray fluorescence, and laser-induced breakdown spectroscopy are also described  ...  Remote Sensing The term "remote sensing" is used broadly, from the visual inspection of plants over the tractor mounted sensors described in Section "Chlorophyll Detection by Vis-NIR" and "Vis-NIR for  ...
