Description
The results of a long-term research of the influence of various biologically active agents (a humic preparation Lignogumat and microbiological Baikal EM fertilizer) on a structural state and the enzymatic activity of ordinary carbonated black soil are presented. It has been established that biologically active substances contribute to increased enzymatic activity, humus and improve the soil structure

REGULARITIES OF THE SEASONAL DEVELOPMENT OF WOODY PLANTS AT INTRODUCTION IN ROSTOV-ON-DON
DescriptionThe article presents the average and optimal calendar dates of the main phenological phases exotic woody angiosperms in Rostov-on-Don. We assess the level of variability timing of individual phenological phases. The data obtained can be used to diagnose the prospects of exotic woody plants for the regional culture

Description
In this article we present the analysis of all the theoretic approaches for modernization and maintenance of historical centers of the cities by the design sources in the point of view of systemic approach to the investigation of the problems. It is revealed that in the concerning area there is a wide experience of investigations and also a big number of various attempts of creation and development of methodological apparatus, which determines the strategy of application of the design products to urban environment in general and to historical environment in particular. However, the complex of scientifically-based solution of the problems in indicated sphere has not developed yet, and as a consequence, the common strategy of maintenance and modernization of historical centers by the design sources are not determined yet. These results of carried out investigations can become a basis for the development of systemic approach for conflict-free penetration into natural historically formed context of the design objects and the saturation of the existing environment

Description
The accumulation features of radionuclides in the epitaphic pylaisiella moss (Pylaisia polyantha) in the territory of the city of Rostov-on-Don have been considered. The specific activities of 137Cs, 226Ra, 40K, and 232Th in the samples of moss, soils, and aerosol air have been compared. The capacity of Pylaisia polyantha to accumulate radionuclides has been estimated for four radionuclides (137Cs, 226Ra, 232Th, and 40K) with consideration for the background level. On the basis of radionuclide analysis, zones in the city of Rostov-on-Don with the highest accumulation coefficients of 137Cs, 226Ra, 40K, and 232Th were revealed. These were primarily the zones with both industrial and traffic loads and the motor transport zones

RELIABILITY OF ESTIMATION OF HEAVY METAL CONTAMINATION IN SOILS
DescriptionThere have been examined the methods for estimating the degree of heavy metal contamination in soils. There have been revealed some discrepancies that concern estimation of soil contamination degree and calculation of consolidated figures for chemical elements contamination in soils stated in effective normative documents. The formulas for estimation of summary soil contamination stated in normative documents reveals considerable discrepancies that do not let give an objective estimation of dangerous concentration of heavy metal. We offer estimation of concentration of several chemical elements not by summarizing their concentration but by estimating their excess in relation to rock or its concentration in soil taken as a background
