Journal Title: FOLIA GEOGRAPHICA - Year 2009, Vol 49, Issue 1

Abstract

Similarly as ecosystem soil provides many services and goods that in soil science are named as soil functions. Besides biomass production, that is possible economically evaluate, the soil provides other ecological functions that are priceless for the society. Sustainability of societal development requires maintenance of soil quality and soil functions - especially the ecological ones. Principles and results of economic valuation of selected soil ecological functions are presented. A verage values of selected ecological functions of agricultural soils in Slovakia are based on previous index evaluation of these functions and defined assumptions and represent 4943 € per hectare for water retention, 4720 € per hectare for filtration of organic and inorganic pollutants and 4336 € per hectare for transformation of organic pollutants, respectively. Valuation of soil and its ecological functions seems as possible way for improvement of soil protection especially in modification of soil price at its permanent sealing but financial values should not to be used as a ground for forming ethical values, which are imminently connected with human approach towards soil and its degradation, and which are essentially needed by global society
