Climate regulation

The capacity of a soil to reduce the negative impact of increased greenhouse gas (i.e., CO2, CH4, and N2O) emissions on climate, among which its capacity to store carbon.


CO2 equivalent

A metric measure used to compare the emissions from various greenhouse gases on the basis of their global-warming potential (GWP), by converting amounts of other gases to the equivalent amount of carbon dioxide with the same global warming potential. Carbon dioxide equivalents are commonly expressed as million metric tonnes of carbon dioxide equivalents, abbreviated as Mt CO2e. The carbon dioxide equivalent for a gas is derived by multiplying the tonnes of the gas by the associated GWP: Mt CO2e = (million metric tonnes of a gas) * (GWP of the gas). For example, the GWP for methane is 21 (minus 1 unit if pertaining to biogenic CH4 as that would alternatively have become 1 CO2) and for nitrous oxide 310. This means that emissions of 1 million metric tonnes of methane and nitrous oxide respectively is equivalent to emissions of 21 and 310 million metric tonnes of carbon dioxide.


Coating

Layer of a substance completely or partly covering a surface of soil material; coatings can comprise clay, calcite, gypsum, iron, organic material, salt, etc.

Colloid

Particle, which may be a molecular aggregate, with a diameter of 0.1 to 0.001

Colluvial

Pertaining to material or processes associated with transportation and/or deposition by mass movement (direct gravitational action) and local, unconcentrated runoff on slopes and/or at the base of slopes.

Colluvium

Unconsolidated, unsorted colluvial material.

Comminuters

Organisms that shred organic material into smaller pieces.

Competitiveness of a farm

Ability of a farm to offer products and services that meet the quality standards of the local and world markets at prices that can hold its own against competing products and services and provide adequate returns on the resources employed or consumed in producing them.

Competitiveness of a region or sector

Ability to create public and private institutions, infrastructure and a macro-economic environment that allows its firms to offer products and services that meet the quality standards of the local and world markets at prices that can hold its own against competing products and services and provide adequate returns on the resources employed or consumed in producing them.

Compost

The material used to supply organic matter or plant nutrients to a soil, resulting from composting.
