"Mechanized windrowing in the top region of the Orlick\u00E9 hory Mts. has disturbed hundreds of hectares of immission clearcuts during eighties. The soil surface on the Velk\u00E1 De\u0161tn\u00E1 Mountain was disturbed in 1987. One year later the Forest Research Station at Opo\u010Dno established on this place the long-term research plot. Degree and extent of soil surface disturbance were recorded. Besides other experiments, the experimental Norway spruce plantation was established on three strips: control strip, strip treated by fertilizers or limestone (1991), and strip ameliorated by Alnus viridis plantation (1992). The effect of site degradation by mechanized windrowing has been indicated by young spruce growth for a long time period. The assessment of 17 years old spruce growth on the control strip shows significantly greater height increment on negligibly disturbed sites comparing to that on remarkably and very remarkably disturbed sites. Amelioration of spruce trees brings perspective outcomes on the strip biologically amended by Alnus viridis. High atmospheric depositions especially of nitrogen compounds, fungal disease by Ascocalyx abietina, climatic fluctuations, and high values of groundlevel ozone have brought new problems into spruce plantation performance since 1999. Nevertheless, it has been more substantially reduced by green alder."@en . . "1803-2451" .
