Col d'Olen, soil chemistry (extractable N-NH4) 2008-2019

Dataset provides information about soil temperature, soil C and N dynamics at different sites in the alpine tundra, along an elevational gradient from 2500 to 2900 m asl during the period 2005-2018. The soil was sampled in triplicate in each the sites and the N-NH4 concentration is measured in soil K2SO4 extracts. The ongoing studies aimed at investigating how the meteorological variables affect the biogeochemistry of seasonally snow covered areas, with a special focus on the effect of the snow cover duration on soil and water C and N dynamics during the growing season.

本数据集收录了2005-2018年期间，沿海拔2500至2900米（asl）的高山冻原不同样地的土壤温度、土壤碳（C）与氮（N）动态相关数据。所有采样点均采用三次重复采样方案，并通过硫酸钾（K₂SO₄）浸提液测定了土壤中的铵态氮（N-NH₄）浓度。本项在研研究旨在探究气象变量对季节性积雪区域生物地球化学过程的影响机制，重点关注积雪持续时间对生长季内土壤与水体碳、氮动态的调控作用。
