Evaluation of mitigation of the effects of heavy metal contamination of soil by adding organic matter Ocena możliwości łagodzenia skutków zanieczyszczenia gleby metalami ciężkimi poprzez dodatek materii organicznej DOI:10.15199/62.2015.5.19


  The soil based on loamy sand was mixed up with aq. solns. of Cd(NO3)2, Pb(CH3COO)2 and ZnSO4 and then with lignitebased fertilizer, lignite, peat, farmyard manure, or dolomite. In all cases, 5 t/ha of org. C was added to the soil. The manurial value of org. substance originated from various sources (expressed as plant crop) was the highest for the lignite-based fertilizer and the lowest for peat. The addn. of org. substance to the heavy metals-contg. soil resulted in increasing content of P in maize roots. The content of Na in the maize above-ground parts did not depend on addn. of org. matter to the soil. Do gleby płowej właściwej (wg WRB, Haplic Luvisols) wytworzonej z piasku gliniastego lekkiego na glinie lekkiej wprowadzono metale ciężkie w formie soli ZnSO4, Pb(NO3)2 [...]
