Sažetak
The World Reference Base for Soil Resources (WRB) is a soil classification system accepted by the International Union of Soil Sciences (IUSS). Its final version was published in 2006. The main purpose of constructing this system was to correlate national soil classifications with the WRB, in order to make communication between scientists in the field of soil classification in the World
possible. The need for informations concerning correlations of national soil classifications with the WRB is pronounced more and more every day. Because of that, systematic field and laboratory soil research, in accordance to the new criteria and regulations given by the WRB, has recently begun in Croatia. Because of the WRB´s great importance for a wide array of scientists with a special interest in soil science, basic informations about the WRB, as well as the principles, key and rules, which have to be followed when classifying soils, are presented in the first part of this article. In its second part, the examples of classification of three characteristic soil types according to the Croatian soil classification and their correlation with the WRB are shown. Some possible problems which may occur while using the WRB classification system and some flaws detected in the classification process, as well as some suggestions for improvement of the WRB, are given in the end.
