Název v původním jazyce

Aboveground biomass of substitute tree species stand with respect to thinning ? European larch (Larix decidua Mill.)

Popis výsledku v původním jazyce

This study is focused on substitute European larch stands in the Krušné hory Mts. (northern part of the Czech Republic). Research was conducted within larch thinning experiment Kalek (780 m a.s.l. in the category Piceeto-Fagetum oligo-mesotrophicum ? Calamagrostis villosa). Results showed that the aboveground biomass of the investigated substitute unthinned larch stand represented approximately 102 thousand kg of dry matter per ha at the age of 20 years. Stemwood (ca 59%) is the most important part of the aboveground biomass. Needles, live and dead branches accounted approximately for 6%, 17% and 11%, respectively, and stem bark only for 7%. At the age of 20 years, the investigated substitute unthinned larch stand accumulated: nitrogen ? 307 kg, phosphorus ? 21 kg, potassium ? 136 kg, calcium ? 122 kg, magnesium ? 53 kg per hectare. Thinning with consequent removal of aboveground biomass may result in nutrient losses. Especially, the removal of whole tree biomass by thinning for chippi
