Effect of elevated CO2 on carbon and nitrogen distribution within a tree (Castanea sativa Mill.) — soil system
Two-year-old sweet chestnut trees were grown outside in normal or double CO2 atmospheric concentration. In spring and in autumn of two growing seasons, a six day labelling pulse of14C labelled CO2 was used to fol...

Atmospheric Co2Increase and Plant Material Quality: Production, Nitrogen Allocation and Litter Decomposition of Sweet Chestnut
Two-year-old sweet chestnut trees were grown for two other years in a doubled CO2 atmosphere. The result was an increase by 20% of the net production and, as an effect of dilution, a decrease of the nitrogen conc...

Native carbon mineralization of an acid organic soil after use of the chloroform-fumigation method to estimate microbial biomass
Two experiments were carried out on a dysmoder humus sampled from a depth of 2–5 cm from a mixed hardwood forest. In acid soil, the chloroform fumigation-incubation method failed to estimate the microbial biom...
