Abstract
The total annual NNM did not intensify in the CC area: in the upper 0-20 cm soil layer the NNM was 169.9 and 157.0 kg haâ1 in the (GAS) and in the CC, respectively. In both cases, the share of nitrification was 100% and NNM intensity was the highest in July. During the snow-melt in April, both in the GAS and in the CC site the leaching of total N was up to 25 kg N monthâ1, whereas in the rest of study period it was negligible in both sites. Harvesting slightly decreased N2O emission, however, it was low at both study sites (â0.55 to 19.75 and â0.77 to 7.43 kg N2O haâ1 yrâ1 in the GAS and the CC, respectively). Management of grey alder stands by traditional silvicultural methods (clear-cuts) did not to increased hazardous N losses through leaching.
