Cd is considered as toxic heavy metal and a small concentration
of it is hazardous to living beings. Cd is a non-essential element
that negatively affects plant growth and development. Itis released
into the environment by power stations, heating systems, metal
working industries, or urban traffic and agricultural activities [6–
8]. The main sources of Cd in soil include atmospheric deposition
and direct application method such as the use of phosphate
fertilizer and disposal of sewage sludge. Soil treated with
Phosphate fertilizers has Cd input, some fertilizers can contain
Cd up to 300 mg/kg and it can vary with fertilizers [9]. The
continuous fertilization with a high rate of triple super phosphate
(1175 kg/ha/year) for a period of 36 years will result in a 14 – fold
increase in Cd content in the surface soils [10]. There is also the
potential release of Cd to soil from hazardous waste sites where Cd
will bind to organic matter and immobilize cadmium [11]. In soil,
Cd tends to be more available at low pH [12]. The specific objective
of this study was first to determine the extent of accumulation of
Cd in a different type of the soils of Rohtak district, Haryana (India)
and then compared with the concentration of Cd as provided by
Central pollution control board (2007). To find the concentration of
Cd in the soil of Rohtak district, different sites were selected. The
PGPRs (Plant Growth-Promoting Rhizobacteria), Bacillus mycoides
and Micrococcus roseus strains, in addition to resistance to the
high concentration of Pb, Zn, Ni, and Cd could grow in a solid
medium of HEPES-MES (4-(2-hydroxyethyl)-1-piperazineethane-
sulfonic acid and 2-(N-morpholino) ethanesulfonic acid) [13]. To
check the remediation process, pre-cultured media was sprayed on
the soil samples and growth rate was checked at different pH.
