ISRIC World Soil Information Country Series Soil inventory and soil classification in Croatia: historical review, current activities, future directions

map by air photo-interpretation and field checks of one full profile and 10 to 30 augerings per 1000 ha; the mostly compound map units refer to the sub-types of the CYS , which is a six-level hierarchy influenced by earlier European systems; keys and class descriptions are mostly qua litative; a lso, 10 800 geo-referenced profile descriptions with standard laboratory data were recorded. All polygons and profile locations have been digitised; data from 2198 profiles have been systematized in a digital database. The BSMC has been generalised to a Map of Soil Suitability for Cultivation (1:300 000) and Soil Map of Croatia (1:1M) using the FAO 1990 legend. Land use planning in Croatia is most active at the level of the 21 counties, eight of which are developing Land Information Systems at 1:100 000, including the digital BSMC newly-interpreted by soils specialists. Increasing demand can be partly met by re-interpretation and augmentation of the BSMC with a revised soil classification but may, also, require a new survey initiative.
