Notizen:
A sensor which detects the presence of green vegetation against a brown background was used to monitor the establishment of plots of Lolium perenne and Poa trivialis, either hand weeded or unweeded. The spectral assessments obtained by the meter were very closely related to the proportion of ground cover, assessed photographically, and harvested dry weight of the two species, at least up to 100 days (approx. 50% ground cover) from sowing, Such spectral assessments therefore provide a rapid, non-destructive method of monitoring changes in green-leaf biomass of establishing grasses. In a complementary investigation the meter provided accurate and objective assessments of scorch damage to grasses caused by various herbicides.
