The research aimed to construct mapping soil variability within the landscape. The research was located in Central Lampung (308 ha). The survey type was detailed using topographic maps (scales of 1:5,000) and the aerial photo interpretations. The soil samples were performed by soil pits and borings for whole survey area (1 composite sample/ha), classified and analyzed. The balancing methods used transect diagrams, delineated soil bodies and area point statistics. The research resulted that the

A combination of aerial imagery, topographical maps and field observations provide the most effective approach for soil mapping in complex landscapes with simple soil patterns. Although the soil sampling was carried out relatively systematic according to relief form and the driving lanes of tractors, there was some agreement between point statistics and map data. The difference between both methods was maximally 3 %. The result combination from both methods shows that 60 % of the landscape was classified as eroded, 35 % as normal and 5 % as colluviated. There was no balance of erosion and onsite sedimentation.
