Soil nitrogen availability vs. acidification: effects on soil respiration, heterotrophic respiration, and soil physicochemical properties in mixed temperate forests in central New York, USA (2019-2022)

In 2011, an experimental nitrogen x pH manipulation study was initiated in mixed temperate forests in central New York, USA to disentangle the often-confounded roles of nitrogen (N) and soil pH in driving various ecosystem processes. This data package contains soil physicochemical properties (soil pH, resin available nitrogen), soil temperature, in situ soil respiration, and heterotrophic respiration measured from laboratory incubations of soils collected from experimental plots. Soil pH was measured both pre-treatment (2009-2010) and after 8 and 11 years of experimental treatment. All other properties were measured between 9 and 12 years after treatment initiation.

2011年，研究团队于美国纽约中部的温带混交林内启动一项氮素与土壤pH调控野外控制实验，旨在厘清长期以来易被混淆的氮（N）与土壤pH在驱动各类生态系统过程中的作用机制。本数据集涵盖土壤理化性质（土壤pH值、树脂可提取态氮）、土壤温度、原位土壤呼吸速率，以及从实验样地采集的土壤经实验室培养后测得的异养呼吸速率。研究分别在实验处理前（2009-2010年）以及实验实施8年、11年后测定了土壤pH值；其余所有指标均在实验启动后的9至12年间完成测定。
