Soils were sampled from the plots with four variants of fertilisation: Nil – without fertilisation, NPK – mineral fertilisation, FYM – farmyard manure, FYM + NPK – farmyard manure with mineral fertilisation, and two variants of crop rotation: field IV – classical 9-year crop rotation, field B – 2-year rotation of alternative growing. Determination of urease, CFU of <I>Azotobacter</I> spp. and potential nitrogenase activity was conducted during the period 1999–2004. The urease activity was positively affected by manure fertilisation (FYM) and by the combination of FYM + NPK. The statistically significantly highest counts of <I>Azotobacter</I> spp. and the highest nitrogenase activity were determined on field B in variants FYM and FYM + NPK. The results show that there was a higher amount of accessible nitrogen present on field IV than on field B. This might explain the lower counts of <I>Azotobacter</I> spp. and therefore the lower nitrogenase activity. According to our results, activity of urease, CFU of <I>Azotobacter</I> spp. and potential nitrogenase activity are very closely connected with N inputs.

The Impact

: In November 2004, forest stands in the Tatra National Park (TANAP) were affected by windthrow and in July 2005, the wildfire broke out on a part of the affected area. The objective of this study is to evaluate the impact of the windthrow and fire disturbances on soil microbial activity. Basal and potential soil respiration, N-mineralisation, catalase activity, soil microbial biomass, and cellulase activity were measured in soil samples taken from the A-horizon (depth of 0–10 cm) along 100 m transects established on 4 plots (reference site, burnt, non-extracted, and extracted sites) in October 2006. Some soil microbial characteristics exhibited a high spatial variability, especially microbial biomass and N-mineralisation. Significant differences in soil microbial characteristics (especially basal soil respiration and catalase activity) between plots were found. Generally, the highest microbial activity was revealed on the plot affected by fire. Soil microbial activity was similar on the extracted and non-extracted sites.
