Czynniki glebowe oraz nawozowe wplywajace na przyswajanie metali ciezkich przez rosliny

Role of some soil and fertilizer factors at the uptake of heavy metals by plants was characterized in the paper. The following factors were considered: kind and contents of heavy metals in soil, soil pH-value and liming, humus content in soil and applied organic matter fertilization, content of clay minerals in soil and application of different adsorbents, content of Al-, Fe-, Mn-oxides in soil and their application, soil redox potential, nitrogen and phosphorus fertilization, and content of salts in soil solution. It was highlighted, that some of these factors are really important in fertilization technology. They may be used to reduce the bioavailability of heavy metals to plant. To these fertilizer factors the liming, application of organic matter at high humification level, application of nitrogen fertilizers, which increase the soil pH-value (N-NO₃), and application of potassium fertilizers in form of sulphate are to be included.
