Biomass of dwarf pine in the Orlické hory Mountains
In order to evaluate weight and nutrients content in dwarf pine biomass, sample trees were taken for destructive analysis in the formerly air-polluted Orlické Hory Mountains. Investigated stand of dwarf pine was planted in 1988–1989 within clear-cut at elevation 1060–1110 m (NW aspect, Sorbeto - Piceetum). Totally 29,000 kg.ha-1 of dry biomass was accumulated in the stand. Above-ground biomass accounts for 27,000 kg (needles 8,000 kg and wood 19,000 kg) and main root biomass represents ca 2,000 kg.ha-1. The biomass of dwarf pine stand contained following amounts of nutrients per hectare: 153 kg of Nitrogen (from this 64 % in needles, 27 % in wood and 8 % in roots), 14.5 kg of Phosphorus (52 % in needles), 46 kg of Potassium (52 % in needles), 22 kg of Calcium (45 % in needles) and 15 kg of Magnesium (40 % in needles and 44 % in wood).
