1.8 CF Standard Names: [MassContentOfNitrogenInVegetationAndLitterAndSoilAndForestryAndAgriculturalProducts] Mass Content of Nitrogen in Vegetation And Litter And Soil And Forestry And Agricultural Products
description: "Content" indicates a quantity per unit area. "Vegetation" means any living plants e.g. trees, shrubs, grass. "Litter" is dead plant material in or above the soil. It is distinct from coarse wood debris. The precise distinction between "fine" and "coarse" is model dependent. The "soil content" of a quantity refers to the vertical integral from the surface down to the bottom of the soil model. For the content between specified levels in the soil, standard names including "content_of_soil_layer" are used. Examples of "forestry and agricultural products" are paper, cardboard, furniture, timber for construction, biofuels and food for both humans and livestock. Models that simulate land use changes have one or more pools of carbon that represent these products in order to conserve carbon and allow its eventual release into the atmosphere, for example, when the products decompose in landfill sites.
