Biomasa i przeksztalcenia systemow korzeniowych sosny zwyczajnej [Pinus sylvestris L.] w warunkach siedliskowych zrekultywowanego wyrobiska i zwalowiska gornictwa odkrywkowego

The paper analyses the biomass and the deformation of the root systems of the Scots pine growing on an afforested post−mining area. Deformation of the root systems was detected in the pines growing on excessively compacted soils of a dump and in the pines growing in a sand mine pit with a shallow groundwater table. In both cases, the ratio of root biomass to aboveground biomass was considered too low, which might indicate a risk to stand nutrition and stability.
