Studies of heavy metals in soil in the Republic of Macedonia show that there are arround 1000 ha in the region along the Zletovska river contaminated with heavy metals with a significant impact of cadmium (Boev B. and Sonja Lepitkova, 2004). Studies made in China (Zhou Qixing & Song Yufang, 2004) also showed that in its southern part there are about 230 000 ha contaminated with cadmium. These regions could be a great potential for production of agricultural crops, but because of their pollution the potential is unused. The aim of this project is to exam the ability of different soybean varieties (Glycine max) and lines from different countries, in their ability to remove cadmium from the soil. World research data shows that soy can be used as remedijator of heavy metals from soil. But studies that have been made so far do not provide for treatment of soybean seeds with a suspension of rhizobacteria. On the other hand, studies made on rhizobacteria shows that these bacteria have the ability to eliminate heavy metals from the soil (Khan et al., 2007). Therefore we believe that soybean plant with its ability of remediation of heavy metals and the opportunity to make symbiosis with rhizobacteria (Bradyrhizobium japonicum) could be the best opportunity for this purpose. According to La Rue and Paterson (1984) soybean crop in the vegetation can fixed 60-168 kg N / ha and improve soil structure.
