usable field capacity (100)

Representation of the aggregated usable field capacity up to a depth of 100 cm (NFK 100). Determined using the link rule 1.11 of the “Method Documentation Soil Science” (as of 2005). The basis is the normal profiles of the concept floor map 1:25.000.100厘米深度范围内聚合有效田间持水量（NFK 100）的表征。该数据集依据2005版《土壤科学方法文档》中的关联规则1.11测算得到。其数据基础为比例尺1:25000的概念底图的标准土壤剖面。
