Chemical and Biological Features of Soils of Urban Territories
Journal Title: International Journal of Advanced Biotechnology and Research. - Year 2016, Vol 7, Issue 2
ABSTRACT There have been observed chemical and biological qualities of urbanized soils and soil-like bodies of the city of Kazan. There has been given an assessment of their enzymological (urease ) activity of the speed of degrading of urea, of reaction of soil solution, of contents of organic carbon. It is shown that chemical and biological qualities of studied soils have been seriously transformed and significantly differ from the complex of qualities of original natural analogs. There has been discovered the increase of pH of soil solution up to 7,0-8,2, high variation in contained organic substance, available forms of elements of nutrients of plants (nitrogen, phosphorus, potassium), flexible compounds of heavy metals and variety of activity of enzyme of urease. There has been discovered the absence of dependence of enzymological activity of city soil-like compounds from their acid-alcaline conditions and contained organic body. The necessity to work out new approaches and methods of studying urban soils and with the aim to assess their ecological state and forecasting of their impact on the city environment.
