Laser sensors in the future? Plant mass can also be determined with laser techniques.

摘要

Site-specific fertilizer use is based on plant mass. The use of lasers in combine harvesters to measure plant mass is described. Two sensor systems (Acuity and Lase) were compared on 14 July 2006 in winter wheat and on 1 December 2006 in winter rapeseed in Germany. Reference data originated from a mechanical Crop Meter sensor. Sensors provided high correlations between average reflection height and plant mass density.
