Abstract

Nitrogen mineralization in a Scots pine forest soil was studied by incubation of soil samples for 6-week periods. Soil samples incubated in the laboratory and in the field differed in nitrogen mineralization rate, mainly because of different temperature, moisture and substrate heterogeneity. Incubation of litter, humus and mineral soil samples in the field during two consecutive years resulted in low rates of mineralization or immobilization. The mineralization rate estimated for the whole soil profile during the growing season was far too low for maintaining the plant community with mineral nitrogen. It is suggested that the low mineralization rates in the incubated samples are caused by fine-root death, which in the present soil of high C/N ratio results in initial immobilization.
