Instrumental neutron activation analysis was used to determine concentrations of 28 elements in soil, roots and leaves of wheat seedlings. To enhance the uptake of the elements, wheat seeds were treated by bacteria Cellulomas sp. 32. In addition, a small amount of CaCl₂ was added to the soil. The micro-organisms affected uptake of nutrients in such a way as to increase concentrations of elements both in roots and leaves of plants. As a result, elemental composition of soil in rhizoshpere zone was also changed. On the other hand, there was no important variation found in element uptake after addition of Ca to the soil.
