Künstliche Huminsäuren , die in einem hydrothermalen Prozess aus Biomasse produziert werden, sind ein praktischer Weg, um ansonsten unlösliche Phosphorspezies zu lösen, wie F. Yang, M. Antonietti et al. in ihrer Zuschrift auf S. 18989 zeigen. Das Bild ist einem berühmten chinesischen Kunstwerk, “Der Mann, der die Berge brach”, entlehnt. Es symbolisiert die Zerkleinerung von Phosphatgestein zur Nährstoffversorgung...
Artificial humic acids (A‐HA) made from biomass in a hydrothermal process turn otherwise highly insoluble phosphates (e.g. iron phosphate as a model) into highly available phosphorus, which contributes to the fertility of soils and the coupled plant growth. A detailed electron microscopy study revealed etching of the primary iron phosphate crystals by the ‐COOH and phenolic groups of humic acids,...
