In the present work the state of soil monitoring (SM) in Estonia, and the theoretical background and aspects of SM arrangement are analysed. In this work SM is divided into different parts, which are: taxonomic or systematic SM in the principal monitoring areas; supplementary or background monitoring carried out in complex monitoring areas; humus cover or humus status monitoring; monitoring of soil pollution or contamination; biological SM or monitoring of soil edaphon; regional or local SM; and monitoring of soil degradation. The first of these is the main or basic SM method, the others are monitoring methods for specific purposes. For SM a list of key soil species was compiled, where the soils are divided into five categories according to their relative importance. SM is arranged in a way which enables to evaluate the stages of changes taking place in soil properties and in their functioning, as well as to estimate their level of danger for environment, and to preview the development of these processes. This data is needed for the arrangement of sustainable management of soil resources, and for scientifically grounded utilisation and protection of other parts of natural ecosystem
