2014We assessed the effects of sucrose addition on the biological and chemical properties of
organic soil in clear-cut Norway spruce forests managed with or without wood-ash fertilization
and mechanical site preparation. Sucrose addition increased the abundances of
enchytraeids and tardigrades and soil moisture percentage in the clear-cut areas. Sucrose also
increased nematode abundance in the non-fertilized plots. Sucrose reduced the pool of waterextractable
NH4-N in the soil in the first year, but increased it in the second year. Sucrose
addition did not affect the decomposition rate of cellulose strips. The biomass of ground
vegetation was not affected by sucrose. Carbohydrate addition seems to enhance N immobilization
in clear-cut areas in the short term, and it is suggested that aims at reducing N loss
from disturbed forest soil do not necessarily accelerate carbon loss from the forest ecosystem.

Inspired by nature : Fiber networks functionalized with tannic acid and condensed tannin-rich extracts of Norway spruce bark show antimicrobial efficacy
Jyske, Tuula; Liimatainen, Jaana; Tienaho, Jenni; Brännström, Hanna; Aoki, Dan; Kuroda, Katsushi; Reshamwala, Dhanik; Kunnas, Susan; Halmemies, Eelis; Nakayama, Eiko; Kilpeläinen, Petri; Ora, Ari; Kaseva, Janne; Hellström, Jarkko; Marjomäki, Varpu S.; Karonen, Maarit; Fukushima, Kazuhiko (Frontiers Media SA, 2023)This study demonstrated the antibacterial and antiviral potential of condensed tannins and tannic acid when incorporated into fiber networks tested for functional material purposes. Condensed tannins were extracted from ... -
Contrasting Norway spruce disturbance dynamics in managed forests and strict forest reserves in Slovakia
Potterf, Mária; Svitok, Marek; Mezei, Pavel; Jarčuška, Benjamín; Jakuš, Rastislav; Blaženec, Miroslav; Hlásny, Tomáš (Oxford University Press (OUP), 2023)Forest disturbances are intensifying globally, yet regional drivers of these dynamics remain poorly understood. We investigated recent disturbance intensities in Norway spruce (Picea abies L.) forests in Slovakia ... -
Chemical Changes in the Industrial Extractive-Containing Sidestreams of Norway Spruce (Picea abies) During Storage
Halmemies, Eelis (Jyväskylän yliopisto, 2024)This dissertation focuses on the changes in the chemical composition of Norway spruce (Picea abies) industrial sidestreams during outside storage, with a particular focus on the behavior of hydrophilic and lipophilic ... -
Production of greenhouse gases by logging residue in boreal clear-cut forests
Laihonen, Antti; Aalto, Sanni, L.; Pihlatie, Mari; Tiirola, Marja (Springer, 2024)Forest deadwood is an important carbon reserve, estimated to contain 8% of the total forest carbon. This type of woody debris is recognized as a source of carbon dioxide (CO2), as the carbon is released back into the ... -
From Norway Spruce Bark to Carbon Foams : Characterization, and Applications
Varila, Toni; Brännström, Hanna; Kilpeläinen, Petri; Hellström, Jarkko; Romar, Henrik; Nurmi, Juha; Lassi, Ulla (Dept. of Wood and Paper Science, College of Natural Resources, North Carolina State University, 2020)Fresh bark from spruce Picea abies was milled and extracted with hot water. The extracts were purified in a number of steps in order to get tannin-extracts pure enough to prepare tannin-based carbon foams. The chemical ...
