资源简介：
The ojectives of this study are: a) Long-term monitoring of
ANPP and peak-crop nitrogen yield in moderately grazed and
ungrazed sites. (In conjuction with neutron probe soil water
monitoring.) b) monitor temporal dynamics of life-form nitrogen
concentration. Additional Objective: monitor annual nitrogen
concentrations, yields, ANPP. Additional Objective: to capture
a digital photograph that allows researchers to interpret
biomass in g/m2 or other characteristics of the vegetation.
