Ground map 1:50.000 (BK50)

The BK50 represents the results of the land survey for the scale 1:50,000. Soil type and substrate type are named for the demarcated soil societies (guide and accompanying soil forms). The detailed horizon sequence of the guide soil shapes is described with characteristic soil parameters such as: Horizontal symbols, substrates, soil types, coarse soil proportions, carbonate levels, humus levels and soil hydrological characteristics.BK50代表1:5万比例尺土地调查的成果。土壤类型与基质类型依照划定的土壤群落（标准土壤类型与伴生土壤类型）进行命名。标准土壤形态的详细土层序列通过以下特征土壤参数进行描述：土层标识符号、基质、土壤类型、粗粒占比、碳酸盐含量、腐殖质含量以及土壤水文特性。
