After entering the soil, material of biogenic origin experiences decay and microbial reworking. During these processes, the labile compounds are quickly mineralized into inorganic nitrogen forms, directly available for the production of new biomass. The more stable compounds and metabolic products accumulate to form the refractory organic pool of soils (Kelly and Stevenson, 1996). Their nitrogen will be sequestered from the overall nitrogen cycle and therefore from bioproductivity over a expended time range.
