2006–2022年中国科学院环江喀斯特生态系统观测站农田长期观测样地土壤养分数据集

中国科学院环江喀斯特生态系统观测研究站是我国西南喀斯特地区重要的农业生态系统长期野外定位观测研究站，是依照中国生态系统研究网络（CERN）联网监测规范布置的试验样地。自2005年以来，环江站依照国家生态系统观测研究网络（CNERN）和CERN农田生态系统观测指标要求，逐一开展针对喀斯特峰丛洼地农田生态系统水分、土壤、生物、气象等环境要素的监测活动。本数据集收集、整理了环江站2006—2022年8个长期联网监测样地的土壤养分数据，包括土壤有机质、全氮、全磷、全钾、碱解氮、有效磷、速效钾、缓效钾、pH值等9项指标，均进行了严格的数据质量控制与评估，并附有完整的样地背景信息和分析方法记录。本数据集数据反映了桂西北喀斯特峰丛洼地农业区传统代表性作物早晚稻、玉米、大豆、桑叶、柑橘等农作地土壤常规养分含量动态变化，对指导喀斯特峰丛洼地农业生产、培育土壤地力具有参考依据。

Huanjiang Karst Ecosystem Observation and Research Station, Chinese Academy of Sciences is a key long-term field in-situ observation and research station for agro-ecosystems in the karst region of southwest China, and it was established as experimental plots in accordance with the networked monitoring specifications of the Chinese Ecosystem Research Network (CERN). Since 2005, Huanjiang Station has successively carried out monitoring activities targeting environmental factors including water, soil, biota, meteorology and others in the agro-ecosystems of karst peak-cluster depressions, in accordance with the observation indicator requirements for agro-ecosystems set by the National Ecosystem Observation and Research Network (CNERN) and CERN. This dataset collects and sorts out soil nutrient data from 8 long-term networked monitoring plots at Huanjiang Station from 2006 to 2022, covering 9 indicators including soil organic matter, total nitrogen, total phosphorus, total potassium, alkali-hydrolyzable nitrogen, available phosphorus, rapidly available potassium, slowly available potassium and pH value. All data have undergone strict quality control and assessment, and are accompanied by complete plot background information and analytical method records. The data in this dataset reflect the dynamic changes in conventional soil nutrient contents of croplands growing traditionally representative crops in the karst peak-cluster depression agricultural area of northwest Guangxi, including early and late rice, maize, soybean, mulberry and citrus, and provide references for guiding agricultural production and soil fertility cultivation in karst peak-cluster depression areas.
