Malaysian tropical heath forest growth and chemistry after fertilisation, 2016-2018

The dataset consists of tree diameter at breast height (DBH) of all trees > 1 cm DBH in 16 parcels of 15 m x 15 m in the tropical heath forest of the Kabili-Sepilok Forest Reserve (Sabah, Malaysia). Also included are the tropical heath forest trees’ leaf element concentration. Tree DBH has been measured three times, one before (2016) and two after (2017 and 2018) the experimental application of Nitrogen fertiliser and CaCO3 to the forest floor. The leaves were collected before (2016) and after (January 2017; July 2017; June 2018) the application of experimental nitrogen and CaCO3 fertilisation. The experimental setting consists of four replicate parcels for the control plots, four replicates for the Nitrogen treatment, four replicates for the CaCO3 treatment and four replicates the Nitrogen and CaCO3 treatments combined.

本数据集收录了位于马来西亚沙巴州卡比里-塞比洛克森林保护区（Kabili-Sepilok Forest Reserve）热带常绿灌木林中，所有胸径大于1厘米的树木的胸径数据。此外，还包括了热带常绿灌木林树木的叶片元素浓度。树木胸径数据于氮肥和CaCO3在林地表层实验应用前后三次测量，分别是在2016年之前、2017年和2018年。叶片样本采集同样分为实验氮肥和CaCO3施用前（2016年）及施用后（2017年1月；2017年7月；2018年6月）。实验设置包括四个重复的对照地块、四个重复的氮肥处理地块、四个重复的CaCO3处理地块以及四个重复的氮肥和CaCO3联合处理地块。
