The environmental status of any area is determined by the environment protection value (EPV) of its soils - their properties and functioning. In this work the biological, physical, pedo-climatic and subsoil aspects of the EPV of Estonian post-lithogenic or normally developed mineral soils (72% from total area) have been analysed. The analysis embraces 25 soil groups, the properties of which are presented according to land use (forest, arable and grassland soils) and by different soil layers (humus cover, soil cover and the metric soil layer) on soil matrix tables. On the basis of the results, which were received in the course of the assessment of separate EPV aspects, the EPV class, as an integrated index for soil type, was determined. The soils studied were divided into five classes, according to (I) good, (II) relatively good, (III) satisfactory, (IV) relatively poor and (V) poor EPV.
