Estimating soil organic carbon stocks of Swiss forest soils by robust external-drift kriging
Swiss forest soils robust external-drift kriging
2014/12/18
Accurate estimates of soil organic carbon (SOC)
stocks are required to quantify carbon sources and sinks
caused by land use change at national scale.
Modeling dissolved organic carbon in temperate forest soils: TRIPLEX-DOC model development and validation
Modeling dissolved organic carbon temperate forest soils
2014/12/18
Even though dissolved organic carbon (DOC) is
the most active carbon (C) cycling in soil organic carbon
(SOC) pools, it receives little attention from the global C
budget.
Sensitivity analysis and calibration of a soil carbon model (SoilGen2) in two contrasting loess forest soils
Sensitivity analysis calibration soil carbon model two contrasting loess forest soils
2014/12/17
To accurately estimate past terrestrial carbon pools is the key to understanding the global carbon cycle and its relationship with the climate system. SoilGen2 is a useful tool to obtain aspects of so...
A comparative study of the soil solution chemistry of two Amazonian forest soils (Central Amazonia, Brazil)
soil water chemical composition forest soils
2009/6/8
Analyses of the chemical composition of rapidly percolating soil water were used to study the genesis of a shallow podzol in a Campinarana forest and a clayey ferralsol from a typical rainforest loca...
Simulation of the long-term carbon and nitrogen dynamics in Dutch forest soils under Scots pine
long-term carbon Dutch forest soils nitrogen dynamics Scots pine
2009/6/5
Dynamics of C and N in forest soils in the Nutrient Cycling and Soil Acidification Model (NUCSAM) are described by the transformation and decomposition of three organic matter compartments, litter, fe...
Staining substances have been widely used to visualize flow paths in soils, and recently dye concentrations in soil profiles are quantified using photographs. Fluorescent dye Uranine is one of the pro...
Quantification of nitrate leaching from forest soils on a national scale in The Netherlands
soil modelling up-scaling
2009/3/6
To evaluate the effects of nitrogen (N) emission policies, reliable information on nitrate concentrations and leaching fluxes from forest ecosystems is necessary. Insight into the regional variability...
Sources of nitrous oxide emitted from European forest soils
Sources nitrous oxide European forest soils
2010/1/13
Forest ecosystems may provide strong sources of nitrous oxide (N2O), which is important for atmospheric chemical and radiative properties. Nonetheless, our understanding of controls on forest N2O emis...
Inventories of N2O and NO emissions from European forest soils
Inventories N2O NO emissions European forest soils
2010/1/12
Forest soils are a significant source for the primary and secondary greenhouse gases N2O and NO. However, current estimates are still uncertain due to the still limited number of field measurements an...
Comparison of Soil Fungi Flora in Burnt and Unburnt Forest Soils in the Vicinity of Kargıcak (Alanya, Turkey)
Burnt Forest Soil Microfungi Alanya
2010/3/22
Out of the 50 soil samples taken from burnt forest land in the vicinity of the village of Kargıcak in Alanya and from the adjacent normal forest soils by the Soil Dilution Plate Method 84 differe...
On the Evaluation of Nutrient Pools of Forest Soils
Evaluation Nutrient Pools Forest Soils
2012/2/13
The standard method of assessing the available portion of the nutrient reservoir of a forest soil is to use a neutral salt solution, such as NH4OAc, to extract the exchangeable plus dissolved ions, wh...
