Slovak agriculture has 2,44 mil. ha agricultural soil available for food and raw material production, of which 1,44 mil. ha are plough land. In comparison with the neighbouring countries (Czech Republic, Hungary, Austria) natural fertility of our soil is about 10-18% lower. It is an important fact because it reduces our competitiveness of production and food sale. In addition, in the structure of agricultural soil we register the so called threatened soil fond including immission threatened soils. The soils contaminated by exhalations produce lower crop yields, and production has to be oriented toward crops that are possible to grow but not those that are interesting to the market. As a result, property. loss arises (due to damage and losses). This loss changes, depending on soil contamination. It is in a range of 382 to 1,775 Sk. ha-1.
