Carbon Feedback from Forest Soils will Accelerate Global Warming,26-Year Study Projects
Carbon Feedback Forest Soils Accelerate Global Warming 26-Year Study Projects
2017/10/25
After 26 years, the world’s longest-running experiment to discover how warming temperatures affect forest soils has revealed a surprising, cyclical response: Soil warming stimulates periods of abundan...
Neutralizing acidic forest soils boosts tree growth,causes spike in nitrogen export
Neutralizing acidic soils tree growth causes spike nitrogen export
2016/7/4
A legacy of acid rain has acidified forest soils throughout the northeastern US, lowering the growth rate of trees. In an attempt to mitigate this trend, in 1999 scientists added calcium to an experim...
Degradation of Forest Soils in the Vicinity of an Industrial Zone
acidification contamination toxic elements
2015/7/28
Soils of the study area are acidified and the surface enrichment with Cd, Cu,
Pb, and Zn reflects anthropogenic contamination. Two forms of all PTEs were evaluated: potentially mobilized
(2M ...
Available nitrogen in the surface mineral layer of Serbian forest soils
A-value C/N ratio total organic C total soil N
2015/3/27
Based on a greenhouse experiment, we evaluated nitrogen availability in the surface mineral layer of soil under various deciduous forest stands by analysing the following soil characteristics: total o...
Saturated hydraulic conductance of forest soils affected by track harvesters
forest soil saturated hydraulic conductivity hauling technology Guelph permeameter
2015/3/27
The exact data from the field of soil mechanics from specific forest stands exposed to forestry mechanization operation were obtained. Field surveys were performed on four study plots within the K"...
Possibilities of using the portable falling weight deflectometer to measure the bearing capacity and compaction of forest soils
deflection E-module PFWD soil bearing capacity soil compaction soil reaction
2015/3/20
The paper discusses possibilities of using the portable falling weight deflectometer to measure the bearing capacity and compaction of forest soils. Within the study, measurements were made using manu...
Development of forest soils in the Krkonoše Mts. in the period 1980–2009
acidification air pollution Krkonoš e Mts liming multidimensional analysis soil dynamics
2015/3/19
This paper documents the development of soil conditions in the set of 32 permanent research plots in the Krkonoše (Giant) Mts. These plots represent an altitudinal gradient covering the ecosystem...
Effects of spruce, beech and mixed commercial stand on humus conditions of forest soils
tree species composition soil forest floor reserves
2015/3/16
A pedological survey was carried out in a spruce monoculture, beech stand, and in a mixed stand at a field research station in R醞ec-N靘鑙ce of the Institute of Forest Ecology (IFE), Mendel University of...
Sorption of heavy metals in organic horizons of acid forest soils at low added concentrations
acidic soils adsorption desorption organic matter risk elements
2015/3/13
The individual adsorption/desorption of Cu, Pb, and Zn in six soil samples taken from organic horizons of acid forest soils is studied in batch experiments. These three metals were chosen because of t...
Modelling the impact of acid deposition on forest soils in North Bohemian Mountains with two dynamic models: the Very Simple Dynamic Model (VSD) and the Model of Acidification of Groundwater in Catchments (MAGIC)
air pollution Black Triangle historical deposition long-term modelling mass balance soil solution soil chemistry
2015/3/13
Enormous acid deposition that culminated in the 1970s contributed largely to accelerate the process of acidification of soils in northern Bohemia. As a consequence a wide forest decline occurred short...
Fluctuations in the properties of forest soils in the Central European highlands (Czech Republic)
acidification cyclometric functions forest ecosystem soil chemistry time-series
2015/3/10
Fluctuations in forest soil properties were described using a time series analysis of the clay content, the chemical (CaO, MgO, Corg, and Ntot) and physicochemical (pH and base saturation (BS)) soil p...
Mapping the topsoil pH and humus quality of forest soils in the North Bohemian Jizerské hory Mts. region with ordinary, universal, and regression kriging: cross-validation comparison
Black Triangle digital soil mapping geostatistics map accuracy
2015/3/9
North Bohemia belongs to one of the most heavily industrialized and polluted regions in Europe. The enormous acid deposition which culminated in the 1970s has largely contributed to the accelerated ac...

acidification Hruby Jeseník kriged maps soil properties survey spatial distribution
2015/3/3
The Hruby Jeseník Natural Forest Region (NFR) is a border mountain territory which belongs to the areas most heavily impacted by air pollution in the Czech Republic. This paper compares results for so...
Variability of water repellency in sandy forest soils under broadleaves and conifers in north-western Jutland/Denmark
critical surface tension Denmark forest soils hydrophobicity water drop penetration time water repellency
2015/2/3
Soil water repellency has important consequences for ecological and hydrological properties of soils and usually retards infiltration capacity and induces preferential flow. This phenomenon has been k...
Restoration of forest soils on reforested abandoned agricultural lands
afforestation agricultural land soil restoration species composition humus forms litter formation
2015/2/2
Restoration of forest soil character after the change of agricultural land use has not been studied yet despite the large areas reforested since the late 40ies of the last century. This process takes ...
