Lysimeter data Rostock: Soil profiles (Data collection, parent table)

The dataset contains soil profile data from three soil profiles from along a hill slope in Northern Germany. Monoliths of these profiles were later used in lysimeter experiments. Data describe the geographical position, soil- and substrate type as well as the horizon sequence of the three soil profiles. Further, they give the soil sampling depths which were used for soil parameter analyses. They are published in Baumann et al. 2020, Speciation and sorption of phosphorus in agricultural soil profiles of redoximorphic character, EGAH, doi: 10.1007/s10653-020-00561-y

Research question: Controlled drainage may affect phosphorus mobilization in soil. To assess the P mobilization potential, three soil profiles with redoximorphic features were selected along a slight hill slope. Soil profiles were characterized according to the World Reference Base and the German Soil Classification System. Three depths for subsequent soil sampling were chosen. Since soil profiles were excavated during lysimeter monolith sampling, the profiles also reflect the monolith structure in the lysimeters.

本数据集包含德国北部一处山坡沿线3个土壤剖面的剖面数据。上述剖面的原状土柱（monolith）后续被用于渗漏计（lysimeter）实验。数据涵盖了这3个土壤剖面的地理位置、土壤与基质类型，以及发生层序列；同时提供了用于土壤参数分析的土壤采样深度。本数据集相关研究成果发表于Baumann等人2020年刊发的《氧化还原敏感型农业土壤剖面中磷的形态与吸附》（Speciation and sorption of phosphorus in agricultural soil profiles of redoximorphic character），刊载于EGAH，DOI: 10.1007/s10653-020-00561-y。

研究问题：受控排水可能会影响土壤中磷的迁移活化。为评估磷的迁移活化潜力，研究人员沿一处缓坡选取了3个具有氧化还原形态特征的土壤剖面。依据世界土壤资源参比基础（World Reference Base）与德国土壤分类系统对各土壤剖面进行了表征，并选定了3个后续土壤采样的深度。由于这些土壤剖面是在渗漏计原状土柱采样过程中挖掘得到，因此其剖面结构也与渗漏计内的原状土柱结构一致。
