description"Content" indicates a quantity per unit area. 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. The phrase "expressed_as" is used in the construction A_expressed_as_B, where B is a chemical constituent of A. It means that the quantity indicated by the standard name is calculated solely with respect to the B contained in A, neglecting all other chemical constituents of A. The chemical formula for the ammonium cation is NH4+. The quantity with standard name soil_mass_content_of_inorganic_nitrogen_expressed_as_nitrogen is the sum of the quantities with standard names soil_mass_content_of_inorganic_ammonium_expressed_as_nitrogen and soil_mass_content_of_inorganic_nitrate_expressed_as_nitrogen.
