Metsätalouden vesistökuormitus: nykykäsitys ja tulevaisuuden menetelmäkehitys

Autor: Mika Nieminen, Samuli Launiainen, Paavo Ojanen, Sakari Sarkkola, Ari Laurén

Publikováno v: Metsätieteen aikakauskirja, Vol 2020 (2020)

Metsätaloutta on pidetty valtakunnallisesti melko vähäisenä vesistökuormittajana. Tämä perustui käsitykseen, että metsäojituksen ja muiden metsätalouden toimenpiteiden vaikutukset vesistökuormitukseen ovat suhteellisen lyhytaikaisia; 10�

Temperature sensitivity patterns of carbon and nitrogen processes in decomposition of boreal organic soils - Quantification in different compounds and molecule sizes based on a multifactorial experiment.

Autor: Ari Laurén, Mari Lappalainen, Antti-Jussi Kieloaho, Kristiina Karhu, Marjo Palviainen

Publikováno v: PLoS ONE, Vol 14, Iss 10, p e0223446 (2019)

Climate warming and organic matter decomposition are connected in a recursive manner; this recursion can be described by temperature sensitivity. We conducted a multifactorial laboratory experiment to quantify the temperature sensitivity of organic c

Drainage and Stand Growth Response in Peatland Forests—Description, Testing, and Application of Mechanistic Peatland Simulator SUSI

Autor: Ari Laurén, Marjo Palviainen, Samuli Launiainen, Kersti Leppä, Leena Stenberg, Iñaki Urzainki, Mika Nieminen, Raija Laiho, Hannu Hökkä

Publikováno v: Forests, Vol 12, Iss 3, p 293 (2021)

Drainage is an essential prerequisite in peatland forest management, which generally, but not always, increases stand growth. Growth response depends on weather conditions, stand and site characteristics, management and biogeochemical processes. We c

Nutrient Balance as a Tool for Maintaining Yield and Mitigating Environmental Impacts of Acacia Plantation in Drained Tropical Peatland—Description of Plantation Simulator

Autor: Ari Laurén, Marjo Palviainen, Susan Page, Chris Evans, Iñaki Urzainki, Hannu Hökkä

Publikováno v: Forests, Vol 12, Iss 3, p 312 (2021)

Responsible management of Acacia plantations requires an improved understanding of trade-offs between maintaining stand production whilst reducing environmental impacts. Intensive drainage and the resulting low water tables (WT) increase carbon emiss

Purification of Forest Clear-Cut Runoff Water Using Biochar: A Meso-Scale Laboratory Column Experiment

Autor: Elham Kakaei Lafdani, Taija Saarela, Ari Laurén, Jukka Pumpanen, Marjo Palviainen

Publikováno v: Water, Vol 12, Iss 2, p 478 (2020)

Biochar can be an effective sorbent material for removal of nutrients from water due to its high specific surface area, porous structure, and high cation and anion exchange capacity. The aim of this study was to test a biochar reactor and to evaluate

Hydrology of Drained Peatland Forest: Numerical Experiment on the Role of Tree Stand Heterogeneity and Management

Autor: Leena Stenberg, Kersti Haahti, Hannu Hökkä, Samuli Launiainen, Mika Nieminen, Ari Laurén, Harri Koivusalo

Publikováno v: Forests, Vol 9, Iss 10, p 645 (2018)

A prerequisite for sustainable peatland forestry is sufficiently low water table (WT) level for profitable tree production. This requires better understanding on controls and feedbacks between tree stand and its evapotranspiration, drainage network c
