Impact of long-term nitrogen addition on carbon stocks in trees and soils in northern Europe
TL;DR: In this paper, the effects of fertiliser N on C stocks in trees (stems, stumps, branches, needles, and coarse roots) and soils (organic layer +0-10 cm mineral soil) were quantified by analyzing data from 15 long-term (14-30 years) experiments in Picea abies and Pinus sylvestris stands in Sweden and Finland.
Journal ArticleDOI
Carbon and nitrogen in coniferous forest soils after clear-felling and harvests of different intensity
TL;DR: In this article, three levels of logging-residue harvesting had been applied: (i) conventional stem harvest (residues left on site), (ii) harvesting all above-ground tree parts except needles, and (iii) aboveground whole-tree harvesting (no residues remaining).
Journal ArticleDOI
Decomposition and nutrient release from Picea abies (L.) Karst. and Pinus sylvestris L. logging residues
TL;DR: In this paper, the long-term dynamics of the decomposition of different fractions of forest litters were analyzed by using models derived from a theory on decomposition and element cycling in organic matter.
Journal ArticleDOI
Effects of different forest harvest intensities on the pools of exchangeable cations in coniferous forest soils
TL;DR: In this article, the effects of harvest intensity on exchangeable cations (1 M NH 4 Cl extracts) were examined in four coniferous forest soils in Sweden, 15-16 years after clear-felling.
Journal ArticleDOI
Influence of harvesting intensity of logging residues on ground vegetation in coniferous forests
Bengt A. Olsson,Håkan Staaf +1 more
TL;DR: The results suggest that the major influence of logging residues left on site was related to their nutrient contribution, which tended to decrease over time and, in a long-term perspective, it is suggested that treatment differences in species cover will be small, especially in forests developing dense canopies.
