Silicon and humic acids: modelling of interactions in soil

The physical and chemical processes proceeding at contact of humic acids with oxygen compounds of silicon are studied, and also properties of products formed thus are described. The role of the received soluble and insoluble substances in regulation of agrophysical and agrochemical properties of soils is discussed. It is shown that the balance of concentration of silicon compounds and humic acids defines soil structure, properties, formation and functioning in many respects.
