ABSTRACT In Odisha more than 70 % soils are acidic in nature which requires amelioration measures through liming but some amount of heavy metals are present in liming materials. So in the present investigation the evaluation of heavy metals was done which accumulate through liming in the crop. The field experiment was conducted consecutively for two years (2017-2018) by taking the two crops Maize followed by greengram to study the “Chromium-Cr, Lead-Pb and Cadmium-Cd accumulation in crops through lime materials used as ameliorating material in maize-greengram cropping system grown in acid Alfisols”. Out of two test crops, maize crop accumulated both Cr and Pd where as greengram crop accumulated only Cd. In maize crop, the concentration of Cr was more in root than grain and its stover, but the uptake was more through the stover than grain and the roots. The concentration of Pb was more in the stover than root and grain. Its uptake was more through stover, grain followed by roots. The concentration and uptake of Cd were more in stover than the greengram seed. The lowest concentration and uptake of Cr and Cd were observed in the control practice without soil ameliorants. The calcium silicate having 290 mg/kg Cr and paper mill sludge having 7.0 mg/kg Cd toxic to crops and health hazard to human being also. The stromatolyte source contains very less amount of heavy metals viz. cadmium and chromium but little amount of lead which is very suitable because the concentration an uptake of heavy metals in crops is very less. Among the liming materials the concentration and uptake of chromium followed the order : CS>PMS>ST, the cadmium : PMS>ST>CS and the Lead : ST>PMS>CS. Out of three liming sources the application of Stromatolyte source with Nutrient Expert package gives better results which will be helpful for the extension workers of acid soil areas. |
