Abstract

Sewage sludge can be used to improve forestry soil properties, because it is rich in phosphorus, nitrogen and organic material and, thus, can enhance the growth of tree seedlings in poor quality soils. The study was performed on a site amended with industrial sewage sludge and afforested with birch and pine seedlings. To evaluate the growth of tree seedlings, tree dry biomass, height, diameter, root/shoot ratio, specific root length, shoot and root length were calculated. Higher concentrations of heavy metals and no significant increase in the biomass of trees on sewage sludge amended soil suggest an inhibitory effect of heavy metals on tree biomass growth. - (AM)
