AbstractFull Text

Samples from 2 hardwood (Quercus robur L. and Fagus sylvatica L.) and 4 softwood (Pinus sylvestris L.; Abies Alba Mill.; Picea Abies Karst. and Larix Decidua) were exposed to outdoor and to artificial weathering. The results showed that the rate of erosion depends predominantly on the wood density...

AbstractFull Text

A study was conducted to determine the nutrient use efficiency in oak (Quercus frainetto) and pine (Pinus nigra) in north Greece. Six indices of nutrient use efficiency were evaluated: (1) nutrient concentration in aboveground biomass; (2) net primary production and annual nutrient requirements;...
