1. Acid properties of fulvic and humic acids isolated from two acid forest soils under different vegetation cover and soil depth

Author:
López, R.; Gondar, D.; Iglesias, A.; Fiol, S.; Antelo, J.; Arce, F.

Subject:
nuclear magnetic resonance spectroscopy; acid soils; nitrogen; granite; binding properties; humic acids; soil depth; soil horizons; vegetation cover; protons; forest types; titration; fulvic acids
Abstract:
... We studied the acid-base properties of 16 fulvic acids and 16 humic acids isolated from the surface (3-15 cm) and subsurface (> 45 cm) horizons of two types of acid forest soils, derived respectively from amphibolite and granite rocks, under five different types of vegetation. The observed differences between the contents of humic substances in the two types of soils were related to the degree of ...

2. An improved force-restore method for soil temperature prediction

Author:
Gao, Z.; Horton, R.; Wang, L.; Liu, H.; Wen, J.
Source:
European journal of soil science 2008 v.59 no.5 pp. 972-981
ISSN:

Subject:
heat transfer; loess; mathematical models; plateaus; prediction; soil depth; soil quality; soil temperature; temperature profiles; thermal diffusivity; China
Abstract:
... The force-restore method originally developed to enable soil temperature predictions assumes that soil is uniform with depth (i.e. the vertical gradient of thermal diffusivity is zero in soil) and that thermal conduction is the only heat transfer mechanism necessary for prediction of soil temperature. These assumptions hamper the applicability of the force-restore method to many natural soil condi ...

3. Can we predict the provenance of a soil sample for forensic purposes by reference to a spatial database

Author:
Lark, R.M.; Rawlins, B.G.

Subject:
databases; geostatistics; information sources; kriging; prediction; probability; problem solving; provenance; soil; soil sampling; England
Abstract:
... In forensic soil science it is sometimes necessary to address a question of the form: 'what is the most likely place of origin of this soil material', where the possible provenances are in a large area. This 'intelligence' problem may be distinguished from the 'evidence' problem where we need to evaluate the grounds for believing that some soil material is derived from one site rather than another ...

Abstract:
... One of the best ways to evaluate the coupled heat and mass transfer in soil is to measure the heat flux and water distribution simultaneously. For this purpose, we developed an apparatus for measuring the one-dimensional steady-state heat flux and water distribution in unsaturated soil under reduced air pressure. The system was tested using four samples with known thermal conductivity (0.6-8.0 W m ...

5. Experimental study and modelling of the water phase change kinetics in soils

Author:
Lozano, A.-L.; Cherblanc, F.; Cousin, B.; Bénet, J.-C.

Subject:
models; phase transition; porous media; soil; vapor pressure; vapors
Abstract:
... When dealing with porous media, the liquid-gas phase-change is generally considered instantaneous, while a retardation time is observed in the case of hygroscopic soils. So far, little research has been done to characterize the non-equilibrium behaviour of water phase change. Therefore, we propose a macroscopic model of the liquid-gas phase-change rate in porous media, based on the difference of c ...

Abstract:
... Studies relating macro- and microscopic aspects of impacts of long-term contaminative practices on soils are scarce. We performed such an approach by assessing the fate of metal pollutants in an area close to Paris, where sandy Luvisols were irrigated for 100 years with urban waste water. As a result, these soils display strong accumulation of organic matter, dissolved salts and metal pollutants i ...

Abstract:
... Root exudates help drive the formation of the rhizosphere by binding soil particles, but the underlying physical mechanisms have not been quantified. This was addressed by measuring the impact of a major component of root exudates, polygalacturonic acid (PGA), on the interparticle bond energy and fracture toughness of clay. Pure kaolinite was mixed with 0, 1.2, 2.4, 4.9 or 12.2 g PGA kg⁻¹ to form ...

Abstract:
... In Brazil, most Eucalyptus stands have been planted on Cerrado (shrubby savanna) or on Cerrado converted into pasture. Case studies are needed to assess the effect of such land use changes on soil fertility and C sequestration. In this study, the influence of Cerrado land development (pasture and Eucalyptus plantations) on soil organic carbon (SOC) and nitrogen (SON) stocks were quantified in sout ...

Abstract:
... Information about soil VOC inventories and exchange rates in different soils is very scarce. Seasonality of soil VOC exchange rates is also largely unknown, despite the increasing interest in some soil volatile compounds, such as monoterpenes, because of their important role in soil ecology. We aimed to explore and quantify soil VOC exchange rates in a Mediterranean shrubland and their seasonality ...

ammonia; linear models; prediction; soil pH; variance; volatilization
Abstract:
... There are various circumstances in which it is important to know whether we can treat a model of a soil process as linear with respect to its parameters. In particular this is necessary when we decide how to apply that model so as to generate outputs at different spatial scales. Very few, if any, interesting soil models are strictly linear. However, the assumption of linearity might not be unreaso ...

Hydrochemical processes involved in the development of hydromorphic Podzols are a major concern for the upper Amazon Basin because of the extent of the areas affected by such processes and the large amounts of organic carbon and associated metals exported to the rivers. The dynamics and chemical composition of ground and surface waters were studied along an Acrisol-Podzol sequence lying in an open ...

Abstract:
... Soils containing rock fragments are widely distributed in the world. However, literature on the dynamic simulation of water movement in stony soils is scarce. In this paper, a dual-porosity model was used to simulate water infiltration into soils containing rock fragments. Sensitivity analysis of the dual-porosity model parameters demonstrates that the increase of rock fragment content clearly dec ...

Abstract:
... Amenity turf accounts for up to 4% of land-use in urban areas, providing key refuges for both above- and below-ground biodiversity. Golf courses occupy the largest surface area of all sports facilities; however, only a limited amount of microbial ecology has been carried out to investigate differences in the size and structure of microbial communities of the soil. The soil microbial community is a ...

Seasonal dynamics of soil microbial activity and cell counts were studied along an arctic-alpine altitudinal gradient. The gradient comprised 12 ridges from 1000 to 1600 m altitude. Soil samples were collected during March, May, J ...

Abstract:
... In this paper I discuss sorption curves: choosing them, fitting them, and interpreting them. The Langmuir equation is not appropriate for reaction of ions with soil. Despite some disadvantages, the Freundlich equation is the best simple equation. Fitting sorption equations causes statistical difficulties because sorption is usually calculated from the change in concentration. The two variables are ...
