桂西北峰丛洼地区域土壤有机碳组分（2015-2016年）

提供广西壮族自治区西北峰丛洼地区域不同岩性、不同土地利用类型、不同坡位的土壤轻组有机碳、重组有机碳总氮及其它理化性质，包括轻组、重组、轻组质量、重组质量、含水率、有效磷、土壤容重、pH、有机碳、氮、磷、碳氮比、碳磷比、氮磷比、钾、钠、钙、镁、土壤质地，数据量合计5489条，试验时间为2015-2016年

This dataset provides soil light fraction organic carbon (LFOC), heavy fraction organic carbon (HFOC), total nitrogen (TN), and other physicochemical property data, collected from plots with different lithologies, land use types and slope positions in the northwest peak-cluster depression area of Guangxi Zhuang Autonomous Region. The measured indicators include light fraction, heavy fraction, light fraction mass, heavy fraction mass, soil moisture content, available phosphorus, soil bulk density, pH value, soil organic carbon (SOC), total nitrogen, total phosphorus (TP), carbon-nitrogen ratio (C:N), carbon-phosphorus ratio (C:P), nitrogen-phosphorus ratio (N:P), potassium (K), sodium (Na), calcium (Ca), magnesium (Mg), and soil texture. A total of 5489 valid samples are included in this dataset, and the field experiment was conducted between 2015 and 2016.
