set default values check if tuber, root to total biomass ratio = 0.7 set seed harvest index for trees and grasses to 0.02 determine shape parameters for the plant population-lai equation determine shape parameters for the leaf area development equation The other point used to determine shape parameters for radiation use efficiency is the ambient CO2 level (330 ul/l) and the biomass-energy ratio (bio_e) given for the crop/land cover. ambient CO2 "ambient" bio-e ratio/100 "elevated" bio-e ratio/100
