Molecule‐complexes on Humic‐substances by Structures with ϵ‐Donor‐ and ϵ‐Acceptor‐Qualities For many considerations with reference to the biosynthesis of humic‐substances it is useful to formulate radicals prevailing for certain phases. Some interesting conclusions can be drawn from this conception based on a great number of experiments. The formation of humic‐substances requires radicable materials, i.e. aromatic substances (initial reactants first order, e.g. lignins). The interpretation of X‐ray diffraction allows to estimate the distributation of aromatic and aliphatic share in humic‐substances. The immense possibilities of chemical reactions therefore form extremely complex materials. But their uniformity makes impossible to separate them exactly. Further, with the formation of particles possessing additional properties of mesomerism the stability of the radicals increases, whilst the humification rate decreases.
