Název v původním jazyce

Canopy leaching of nutrients and metals in a mountain spruce forest

Popis výsledku v původním jazyce

Precipitation and throughfall fluxes of major ions, nutrients (C, N, P), and metals (Al, Fe, Mn), and the chemical composition of litter fall and living plant tissue in Norway spruce stands (the Bohemian Forest; Czech Republic), were used to evaluate howmicrobial processes and decay of plant tissue in canopies influence canopy leaching (CL) of elements. Proton exchange for Mg, Ca, and K in decaying biomass and co-transport of Ca and K out of plant cells with organic acid anions were the most likely processes contributing to CL of base cations. The CL of total P and N (and also nitrate) was minor. Important proportions of the N and P mineral forms were transformed to organic forms by microbial processes (primary and bacterial production). Most of particulate P and N in throughfall (90%) originated from microbial SRP and ammonium transformations, but particulate C mostly came from the fragmentation of plant tissue (58%).
