title: [Changes in biological activity of turf-podzolic soil of different mechanical composition contaminated with heavy metals].
abstract: It has been shown that soil pollution with heavy metals (copper, nickel) lead to negative changes in parameters characterizing potential biological activity of soil (nitrogen-fixation, breath, invertase activity, bacteria and fungi count). More profound changes were observed in sandy soil compared to loamy soil. A direct relationship of these effects with the content of mobile forms of heavy metals in soil has been established. For the comparative and prognostic investigation of the danger of soil pollution with heavy metals it has been suggested to use a coefficient of differences in the content of mobile forms and a coefficient of biological effect.
