TL;DR: In this article, a review highlights knowledge of the amount of carbon stored in soils globally, and the potential for carbon sequestration in soil, and discusses successful methods and models used to determine and estimate carbon pools and fluxes.

TL;DR: Validation of models for native and managed Eucalyptus stands confirm their usefulness as a management tool to predict productivity and water use in relation to species, climate and silvicultural options.

TL;DR: The decrease in Al:As with increasing tree size that was observed in the majority of species may be a homeostatic mechanism that partially compensates for decreased hydraulic conductance as trees grow in height.

TL;DR: Evidence is presented that short-term changes in g(s) are linked closely to the hydraulic properties of the conducting system to minimize loss of hydraulic conductivity through xylem by cavitation, and examples of homeostatic mechanisms that operate to ensure the long-term balance between evaporative demand and the potential hydraulic Conductivity of trees growing in different environments are described.

TL;DR: In this article, the concept of soil security is proposed to bridge the gap between what the science tells us about soil and its role in underpinning ecological and human sustainable development, and existing policy instruments for sustainable development.
