I t is well recognized that the trace element content of soils and associated grassland or forage may, under certain conditions of farming practice, influence the health of livestock and the economics of agricultural production. There is also evidence, though mainly empirical, that disease in man may at times be related to the trace metal status of the environment in which he lives. The prime s...

Trenholm for their supportive efforts throughout this learning experience. I give special thanks to Dr. Shober, my committee chair, for her encouragement, direction and commitment. I am also appreciative to Gitta Shurberg for her assistance in the field as well as laboratory. Abstract. Urban soils have highly variable chemical, physical, and biological properties compared to undisturbed natural...

Most urban greening interventions involve soil de-sealing and management to enhance fertility. Management typically requires translocating fertile topsoil the site, which comes at great environmental costs. We hypothesized that de-sealed soils would undergo an increase of their fertility without exogenous application. assessed experimental plots with topsoil, topsoil. Both treatments were veget...

Intensive and diverse human activity in large cities their environs leads to a significant change the environment: relief, hydrographic network changes, natural vegetation is destroyed or replaced by urbophytocenoses, soil cover greatly transformed, climatic characteristics change, i.e. specific type of urban microclimate formed. In cities, anthropogenic impact becomes predominant over factors ...

The aim of this article is to present a sort of state of the art from a soil classification point of view. How far are soils from their original natural state? A few years ago, the two most important soil classification systems added a classification of anthropogenic soils. Even so, although the concept of anthropogenic soil differs slightly in the two systems, it is easy to recognize these soi...

The present study deals with examining the condition of urban soils and their potential to deliver soil-related regulating ecosystem services concerning level anthropogenic pressure in different functional zones Sofia, Bulgaria. Analyses data for selected characteristics superficial 0-10 cm soil layer were performed. Soils sampled from 30 experimental plots within a geo-referred network coverin...
