Litter Decomposition and Microbial Biomass in Temperate Forests in Northwestern Turkey
The purpose of this study was to investigate the influence of microbial biomass on the litter decomposition in relation to litter quality, litterfall, canopy leaf area and soil characteristics. The mean values for litterfall were 4245, 3510 and 2935 kg ha-1 year-1 for beech, fir-beech and fir stands...
