Effects of whole‐tree harvesting at thinning and subsequent compensatory nutrient additions on carbon sequestration and soil acidification in a boreal forest

Autor: Hyungwoo Lim, Bengt A. Olsson, Tomas Lundmark, Jenny Dahl, Annika Nordin

Publikováno v: GCB Bioenergy, Vol 12, Iss 11, Pp 992-1001 (2020)

Abstract Residues from forest harvesting operations may be utilized as a renewable energy source. However, the sustainability of this practice has been questioned due to the losses of nutrients and exchangeable base cations, which may impair the fore

Predicted long-term effects of decomposition of leaf litter from Pinus taeda, Eucalyptus cloeziana and deciduous miombo trees on soil carbon stocks

Autor: Bengt A. Olsson, Benard S. Guedes, A. Sigrun Dahlin, Riitta Hyvönen

Publikováno v: Global Ecology and Conservation, Vol 17, Iss , Pp - (2019)

Decomposition rate of leaf litter in native miombo and in Pinus taeda and Eucalyptus cloeziana plantations was measured in the Inhamacari forest research area, Manica province, Mozambique. The Q-model and a simple first-order exponential decompositio

Net primary production in plantations of Pinus taeda and Eucalyptus cloeziana compared with a mountain miombo woodland in Mozambique

Autor: Benard S. Guedes, Bengt A. Olsson, Almeida A. Sitoe, Gustaf Egnell

Publikováno v: Global Ecology and Conservation, Vol 15, Iss , Pp - (2018)

Planting monocultures of fast-growing non-native (exotic) species is one way to slow or reverse deforestation and forest degradation in tropical zones. This study compared the effects on total net primary production (NPP) of first-rotation monocultur

Plantations of Pinus and Eucalyptus replacing degraded mountain miombo woodlands in Mozambique significantly increase carbon sequestration

Autor: Benard S. Guedes, Bengt A. Olsson, Gustaf Egnell, Almeida A. Sitoe, Erik Karltun

Publikováno v: Global Ecology and Conservation, Vol 14, Iss , Pp - (2018)

Total ecosystem carbon (C) stocks in tree biomass (aboveground and belowground), litter layer and soil (0–50 cm depth) were quantified in mountain miombo woodland and in 34-year-old first-rotation plantations of Pinus taeda and Eucalyptus grandis.

Allometric models for managing lowland miombo woodlands of the Beira corridor in Mozambique

Autor: Benard S. Guedes, Almeida A. Sitoe, Bengt A. Olsson

Publikováno v: Global Ecology and Conservation, Vol 13, Iss , Pp - (2018)

Appropriate allometric models are urgently needed to assess the status and changes in biomass and carbon of the trees in miombo woodlands occupying large geographical areas in Mozambique. This study developed two new and interchangeable allometric mo

Effects of different nutrient compensation treatments following forest fuel extraction on biomass of young Norway spruce (Picea abies (L.) Karst.)

Autor: P.-O. Brandtberg, Bengt A. Olsson, Pei Wang, Helene Lundkvist

Publikováno v: Canadian Journal of Forest Research. 53:188-202

Whole tree harvesting of forests may require compensation for losses of nutrients and alkalinity. The effects of three different practical ameliorative methods on spruce allometry, total biomass, and nutrient uptake were studied in an experiment in a
