Abstract
Soils that have been exposed to flood waters can be heavily polluted by
inorganic and organic compounds. They are mainly compounds which appear in
dissolved or suspended form flowing together with heavily laden
floodwater, as well as compounds created as a result of reactions in the
soil profile, mostly due to anaerobic transformation of organic matter.
Heavy metals brought with flood waters are absorbed by the soil and also
washed out from flood sediments by precipitation when the flood recedes.
This paper presents the results of research on the effects of
fertilization with ash from incineration or pyrolysis of biomass on the
migration process of heavy metals (Zn, Cu, Cr, Ni, Pb, Cd, Mn) in the
arable layer of soil. It has been shown that the metals in the flood
sediment migrate actively in the soil profile what leads to the enrichment
of the soils, also in the case of the soil fertilization with biomass ash.
