Soil improvement system - in which humus nuclei, e.g. naphthalene, anthracene or indole, are added to system contg. carbohydrates, urea and phosphoric acid

摘要

Simultaneous use of synthetic and aromatic systems in which humus nuclei ('Humuskerne'), e.g. napthalene, anthracene or indole are incorporated comprises treating them at acid pH and low redox potential. The system are soil improvement compsn. The dry components of the soil improvement compsn (I) are mixed with the system contg humus nuclei then treated with dil. H3PO4. (I) consists of carbohydrates, urea and H3PO4.
