Application of HS preparation, produced by BioCorrection A/S aided in
accumulation of nitrogen and carbon in soils, stabilization of pH near neutral values. This attests increased stability of the soil organic matter and, correspondingly, reduced emission of greenhouse gases from the soils.
Prevalence of calcium humates within the BioC-HS (Ca) preparation provides
substantial improvement of the structure of clay soils. Water-stability of aggregates is seen substantially improved, opening wide perspectives for application of the BioC-HS in remediation of this type of soils.
It was revealed that biological activity of preparations is to a large degree
dependent on the dosage: low concentrations of the preparation may be inefficient, average – can have stimulating effect and high may possess inhibiting properties. Thus, humic substance preparations may be used both for inhibition and stimulation of soil processes, related to activity of microorganisms; that is why selection of dosages and administration regimens is an important task for researchers, conducting investigation of applied aspects of utilization of humic substances.
