Effect of the skid trail cross section and horizontal alignment on forest soil physical properties
soil bulk density ground-based skidding cross slope Civil3D software Bahramnia forest
2017/6/26
Horizontal alignment and cross section characteristics of a skid trail in a ground-based skidding system including curves, wheel ruts and cross slope can impact on the forest soil. In this study the m...
Detection of the effects of management and physical factors on forest soil carbon stock variability in semiarid conditions using parametric and nonparametric methods
soil organic carbon CART modelling, neural networks
2015/11/26
Forest soils in western parts of Iran are being degraded by inappropriate management. The soil organic carbon (SOC) stock was dominantly affected by this type of degradation. On the other hand, SOC is...
The impacts of ground-based logging equipment on forest soil
dry bulk density moisture content
2015/5/5
Soil properties can be affected by heavy equipment used for skidding but these impacts vary greatly
with site conditions and operational practices. We assessed the effects of ground-based skidding o...
Comparison of the impact of blue spruce and reed Calamagrostis villosa on forest soil chemical properties
Calamagrostis villos upper soil layers quality and quantity Jizersk?hory Mts
2015/3/16
The impact of blue spruce (Picea pungens) and reed Calamagrostis villosa) cover on quantity and quality of upper soil layers was investigated. The research was conducted in the Jizersk?hory Mts., Czec...
Spatial variability of water repellency in pine forest soil
spatial variability water repellency WDPT test infiltration sorptivity
2015/2/3
The variability of water repellency of pine-forest arenic regosols and its influence on infiltration processes were measured in southwest Slovakia. The water drop penetration time (WDPT) tests of soil...
Molecular size distribution and hydrophilic and hydrophobic properties of humic acids isolated from forest soil
forest soil humic acids HPSEC hydrophobic fractions hydrophilic fractions
2015/1/30
The aim of the present paper was to determine hydrophilic and hydrophobic properties and the degree of polydispersity of humic acids depending on their degree of maturity and the properties of the pla...
PRESERVATION OF FOREST SOIL AND VEGETATION IN THE CAPERCAILLIE (Tetrao Urogallus L.) HABITAT WITHIN THE EASTERN KARAVANKE RANGE AND THE EASTERN KAMNIK-SAVINJA ALPS IN SLOVENIA
carbonate and non-carbonate bedrock secondary forest soil characteristics
2009/11/26
In the high-montane zone of the eastern Karavanke range and the eastern Kamnik-Savinja Alps of Slovenia, the soil and vegetation conditions on nine representative plots in the Capercaillie (Tetrao uro...

Soil Profile Alteration in a Brown Forest Soil under High-Input Tea Cultivation.
Comparison of simulated forest soil response to acid deposition reduction with two models of differing complexity
forest soil \acid deposition reduction
2009/6/5
Great effort has been dedicated to developing soil acidification models for use on different scales. This paper focuses on the changes in model performance of a site scale soil acidification model (NU...

acidification manipulation nitrogen deposition drainage microcosms forest
2009/3/5
An experiment comparing effects of sulphuric acid and reduced N deposition on soil water quality and on chemical and physical growth indicators for forest ecosystems is described. Six H2SO4 and (NH4)...
Diurnal Variations of Greenhouse Gas Fluxes from Mixed Broad-1eaved and Coniferous Forest Soil in Dinghushan
greenhouse gas emission absorption flux diurnal variation broad-leaved and coniferous forest Dinghushan Chinese Academy of Sciences
