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%).
