Temporal changes in nutrients in forest soil and roots and root biomass of Fagus sylvatica after P and N fertilization

We report data for nutrients in the organic layer and in mineral soil of Fagus sylvatica forests after P and N fertilization. We separated soil and roots and also report data for root biomass and nutrient contents in these soil layers. In addition, relative soil water contents and pH were measured. The samples were collected in three forests and repeatedly in spring and fall from 2016 to 2018.Â本数据集报告了经磷（P）、氮（N）施肥处理后的欧洲山毛榉（Fagus sylvatica）林有机质层与矿质土壤中的养分含量数据。研究中对土壤与根系进行了分离，同时报告了各土层中的根系生物量与养分含量数据。此外，还测定了土壤相对含水量与pH值。样品于2016至2018年的春季与秋季，在3个林分中重复采集。
