RESEARCH REGARDING THE INFLUENCE OF NPK AND NP FERTILIZATION ON CADMIUM CONCENTRATION FROM WHEAT ANDMAIZE GRAINS, INALONG TERM TRIAL FROM ORADEA
Journal Title: Natural Resources and Sustainable Development - Year 2013, Vol 3, Issue 1
Abstract
The paper is based on research carried out at the Agricultural Research and Development Station Oradea, in long term trial with NPK (placement year 1974) and with NP (placement year 1974). The research carried out during 2010-2012, shows that in all variants that were chemical fertilized, the concentration of cadmium from wheat grains and maize grains was far above the admitted limits. The concentration of cadmium concentration from wheat grains and maize grains increased altogether with the fertilizers’ doses. Regarding the version with NP doses, cadmium concentration from wheat and maize grains, was higher than cadmium concentration from wheat and maize grains, determined at NPK fertilized version. There is a direct interrelation between fertilizer doses of NPK and NP and cadmium concentration from wheat and maize grains; the best quantifications of this interrelation was carried out by polynomial function. During 2010, while the vegetation period of those two crops were registered precipitations over the multiannual average value (1931-2009) of this climatic parameter, cadmium concentration from wheat and maize grains was lower than during 2011 and 2012, when precipitations were registered under the multiannual average value.
