DOI: 10.1016/j.apsoil.2020.103655
Abstract: Abstract The “Soil Continuum Model” questions the occurrence of any independent natural process of secondary synthesis that generates compounds structurally distinct from plant or microbial metabolites. This review shows that a vast volume of interdisciplinary… read more here.
