Hydrostructural characteristics of two African tropical soils

Autor: Rabi H. Mohtar, Erik Braudeau, M. Sene

Publikováno v: European Journal of Soil Science. 56:375-388

Summary This paper describes the characteristic shrinkage curve of a soil as it dries. It also introduces a new method to measure specific soil moisture states such as permanent wilting point and field capacity using the shrinkage curve. The model co

Soil physical degradation and changes in macrofaunal communities in Central Amazon

Publikováno v: Applied Soil Ecology. 26:157-168

In Brazilian Amazonia there are 26 million hectares of degraded pastures. One of the causes of degradation is assumed to be alterations in soil structure that is partly determined by a reduction in soil macrofauna diversity. The objective of this cas

International audience; In the highlands of southern Colombia and northern Ecuador, soils developed on volcanic ash deposits have specific properties: high water retention, high hydraulic conductivity and high carbon (C) contents. The main role of th

Effets des racines, des vers de terre et du compost sur les propriétés physiques de technosols construits

Autor: Deeb, M., Grimaldi, Michel, Lerch, T.Z., Podwojewski, Pascal, Dubs, Florence, Gigon, A., Blouin, M.

Les technosols construits sont une alternative au prélèvement de terre végétale en milieu naturel. La gestion durable de ces technosols suppose de comprendre l'évolution de leurs propriétés hydriques. Nous avons analysé les courbes de retrait

Soil water thermodynamic to unify water retention curve by pressure plates and tensiometer

Autor: Braudeau, Erik, Hovhannissian, Gaghik, Assi, A.T., Mohtar, R.H.

The pressure plate method is a standard method for measuring the pF curves, also called soil water retention curves, in a large soil moisture range from saturation to a dry state corresponding to an applied pressure of near 1500 kPa. However, the pre

Models of the water retention curve for soils with a fractal pore size distribution

Autor: Edith Perrier, Garrison Sposito, Michel Rieu, Ghislain de Marsily

Publikováno v: Water Resources Research. 32:3025-3031

The relationship between water content and water potential for a soil is termed its water retention curve. This basic hydraulic property is closely related to the soil pore size distribution, for which it serves as a conventional method of measuremen

International audience; Due to its position at the interface between the atmosphere and the vadose zone, the soil significantly contributes to the partitioning of rainfall into infiltration and overland flow, and, as a consequence, to the water feedi

Computer construction of fractal soil structures: Simulation of their hydraulic and shrinkage properties

Autor: Edith Perrier, Michel Rieu, Ghislain de Marsily, Christian Mullon

Publikováno v: Water Resources Research. 31:2927-2943

To study relationships between soil hydraulic properties and soil structural properties, a computer micro model of soil is constructed. We present first a general method of building a two-dimensional porous structure, including both pores and particl

Les sols sont définis comme étant caillouteux à partir d’une proportion supérieure à 35 % d’éléments grossiers. Les sols caillouteux - dont certains supportent des zones de grandes cultures - couvrent environ 30% de la superficie de l’Eu
