The investigators filed a utility model application, no. SK 5847 Y12, entitled ?Modular flood barrier structure?. Terms of the type and composition of source material, polypropylene (PP) an...

Biochar is carbonized organic matter, which is prepared by pyrolysis and it content high amount of carbon. This material is currently very often mentioned in carbon sequestration and as an additive improving physicochemical and biological soil functions, especially soil aggregation, conductivity or pH. Thus biochar could be usefully toll for decreased erosion risk. The influence of biochar on soil microorganisms is still big question. Results of scientific work differ much. Problematic component of biochar is arom...
