dc.description.abstract | Heavy metal fluxes in Norwegian agriculture were estimated on the basic of annual sludge production, phosphate fertilization and crop production in the main agricultural areas of Norway. Soil heavy metal input due to atmospheric deposition and output due to leaching were further included from different reports.
In most cases, atmospheric was shown to be the most important source for Cd, Pb, Hg, Ni, and Cr while sludge, to be the most important source of Zn and Cu in Norway. Fertilization contributed the least proportion to soil input with respect to all seven heavy metals except for use of certain types of phosphate fertilizers with high cadmium concentrations. | nb_NO |
