Aquands have a shallow profile and an impermeable layer that restricts water movement. Land use changes alter the physical structure of Aquands and soil air fluxes. The impacts of land use changes on the soil’s biological activity, nutrients’ dyn

The Nadi soils (NS) is a local name for soils occurring at southern Chile (38° to 43° S) covering around 4250 km2 hectares. Derived from volcanic materials, have discontinuous iron-cemented layers (the placic horizon) which favour waterlogging duri

The aim of this work was to evaluate the effect of the land use change (CUS) of a Ñadi soil (Aquands) from secondary forest to naturalised grassland, on the aggregate stability (tensile strength and shrinkage capacity) and its relationship with the

Aquands are shallow depth and frequently waterlogged volcanic ash soils, presenting seasonal dynamics of water content in the soil profile. Land use change and management are expected to alter the Aquands biological activity due to their impact to wa

The aquands found in southern Chile are derived from volcanic ash and contain high levels of organic matter. Due to the presence of an impermeable stratum, they have shallow soil profiles, which induce waterlogging for several months each year. These
