Advanced radar for measuring green area index(GAI), biomass and shoot numbers in wheat (Radwheat)

Abstract

The RADWHEAT project has developed the potential of radar sensors for the quantitative measurement of key parameters of winter wheat (GAI, shoot numbers and biomass). Measurement of these parameters are important in order to improve nitrogen and PGR decision-making accuracy using canopy management principles. Using sensors would provide potentially cheap but objective crop measurements, and would have great value for conventional 'uniform' field management as well as allowing the implementation of appropriate 'precision farming' or variable rate inputs management practices.
