Abstract

NIKOLOV, N. S. and D. P. DIMITROV, 2011. Reducing the accumulation of lead, zinc and cadmium from triticale crop by calcaric fluvisol, using Black Sea sapropelles. Bulg. J. Agric. Sci., 17: 364-367

It was investigated the influence of Black Sea sediments (sapropelles) on the accumulation of Pb, Zn and Cd from alluvial-meadow soil (Calcaric Fluvisol). The survey was carried out with triticale crop by two years pot plants experiment. The result obtained was shown that at an amount 10 g.kg^-1 and 30 g.kg^-1, sapropelles decrease the accumulation of Pb, Zn and Cd from the tested crop at a rate from 5.30 % to 100%.

Key words: sapropelles, accumulation, alluvial-meadow soil, triticale, Pb, Zn, Cd
Abbreviations: DTPA - diethylentriaminepentaacetic acid; MCL - Maximum concentration limit
