Agri-environmental zone (AEZ)

A spatially homogeneous area with distinctive characteristics in terms of the present climate, soil type and slope (http://www.fao.org/nr/land/databasesinformation-systems/aez-agro-ecological-zoning-system/en/).

Cracking

Formation of vertical fissures in a soil which promote the downward preferential flow of water with or without particulate matter or salts.

Acidification

The process in which the concentration of hydrogen ions in the soil gradually increases, caused by removal of (slightly alkaline) crop produce, leaching and the use of acidifying N fertilizer types, accelerated or insufficiently compensated by the natural constituents of a soil among which the parent material.

Carbon sequestration

The capacity of a soil store carbon in a non-labile form with the aim to reduce the CO2 concentration.

Biodiversity and habitat

The multitude of soil organisms and processes, interacting in an ecosystem, making up a significant part of the soil's natural capital, providing society with a wide range of cultural services and unknown services.

Attribute

A characteristic of the soil system contributing to the generation of a soil function. One attribute can contribute to more soil functions. Attributes can be quantified with indicators A concrete aspect of the system (in the case of LANDMARK: plausibly linked to a soil function) for which indicators can be envisaged. Soil pH, NO3-transport to [...]

Agroforestry

A type of land use that combines production on the same plot of land, from annual agricultural activities (such as crops and pasture) and from delayed long-term production by trees (for example timber and services). This is obtained either by planting trees on agricultural land or by cropping (for example after thinning) on forested land. [...]
