Soil profile description from the research site Grinderwald, part of the research unit SubSOM

We conducted a litter manipulation experiment with 13C enriched beech litter at the Grinderwald research site, 40 km north of Hannover, Germany. The study site contains a more than 100 years old beech forest on a Dystric Cambisol. At 2 time points (11.2016, 05.2018), we took soil cores down to 180 cm soil depth and divided them in 15 depth increments. These data serve as a basis for interpretation of the field experiments conducted at this site. Data were adapted from Leinemann et al. 2016. Research domain: Soil Sciences Research question: We studied the contribution of litter-derived carbon (C) in the formation of subsoil organic matter (OM).

本研究于德国汉诺威以北40公里的格林德瓦尔德（Grinderwald）研究样地，开展了一项采用13C富集山毛榉凋落物的凋落物操控实验。该研究样地位于不饱和雏形土（Dystric Cambisol）之上，发育有一片树龄逾百年的山毛榉林。分别于2个时间节点（2016年11月、2018年5月）采集深度达180 cm的土壤岩芯，并按15个深度梯度对岩芯进行分层。本数据集为该样地开展的野外实验解译提供了基础依据，数据改编自Leinemann等人2016年的研究成果。
研究领域：土壤科学
研究问题：本研究旨在探究凋落物来源碳（Carbon，简称C）在亚表层土壤有机质（Organic Matter，简称OM）形成过程中的贡献。
