Résumé

Plant diversity has been shown to significantly increase topsoil aggregate stability of machine-graded ski slopes. We hypothesise that this effect is specific for these disturbed sites and that at sites of low and no disturbance the effect decreases.

Carbone du sol

Le carbone du sol est la matière terrestre solide stockée dans les sols au niveau mondial. Cette appellation comprend à la fois la matière organique du sol et l'ensemble du carbone inorganique constituant les minéraux carbonatés. Le carbone du sol est un puits de carbone par rapport au cycle mondial du carbone, jouant un rôle dans la biogéochimie, l'atténuation du changement climatique et dans la construction de modèles climatiques mondiaux. Le carbone du sol est présent sous deux formes : inorganique et organique.

Soil health

Soil health is a state of a soil meeting its range of ecosystem functions as appropriate to its environment. In more colloquial terms, the health of soil arises from favorable interactions of all soil components (living and non-living) that belong together, as in microbiota, plants and animals. It is possible that a soil can be healthy in terms of eco-system functioning but not necessarily serve crop production or human nutrition directly, hence the scientific debate on terms and measurements.

Soil chemistry

Soil chemistry is the study of the chemical characteristics of soil. Soil chemistry is affected by mineral composition, organic matter and environmental factors. In the early 1870s a consulting chemist to the Royal Agricultural Society in England, named J. Thomas Way, performed many experiments on how soils exchange ions, and is considered the father of soil chemistry. Other scientists who contributed to this branch of ecology include Edmund Ruffin, and Linus Pauling.
