• National digital map for soil cover and agricultural land categories in scale 1:10000
• GIS and programme modules of soil types  in scale 1:10000

Brief description of content:
The information is collected on the base of regulations for applying agricultural land protection law, regulations for applying ownership and agricultural land use law and regulations applied to them, administration Executive soil resources agency  regulation 

• The national digital map for soil cover and agricultural land categories in scale 1:100000 includes information about soil types, agricultural land categories, slopes and exposition above 80% of workable lands in the country, which is digitized and developed in AutoCAD Map 3. It is developed and maintained by Executive soil resources agency
• GIS consists of national digital map about soil cover at about for 5700 dka agricultural lands in scale 1:100000 and including inforamation about: soil types name; mechanical composition of surface horizon; surface horizon stoniness; type of soil forming rock; slope gradient; exposition; average bonitet grade; land use and programme modules about:
• Thematic maps visualization by:
• Soil types
• Soil groups
• Solid rock depth
• Carbonates and toxic salts
•  discharge
• erosion degree
• slopes
• expositions
• group types of enduring land use
• land belonding to one village
• complex choice (if more than one parameters is set)
• bonitet valuations and 22 crops yields for each soil type
• surface water erosion forecasting (actual and potential) based on data about erosion factors and prooved algorithms for relationships between them
• determination of amount of the pollutants (most often as heavy metals) as kg in the eroded (removed) soil and respectively amounts of the pollutants entering in river network

• Paper carrier-reports , accounts
• Map material
• Magnetic carrier- AutoCAD Map, Access, ArcView 3.1
