Vertical profiles of leaf photosynthesis and leaf traits, and soil nutrients in two tropical rainforests in French Guiana before and after a three-year nitrogen and phosphorus addition experiment

We provide a comprehensive dataset of vertical profiles of photosynthetic capacity and important leaf traits, including leaf N and P concentrations, from two three-year, large-scale fertilisation experiments conducted in two tropical rainforests in French Guiana. These data present a unique source of information to further improve model representations of the roles of N, P, and other leaf nutrients, in photosynthesis in tropical forests. To further facilitate the use of our data in syntheses and model studies, we provide an elaborate list of ancillary data, including important soil properties and nutrients, along with the leaf data. As environmental drivers are key to improve our understanding of carbon (C)-nutrient cycle interactions, this comprehensive dataset will aid to further enhance our understanding of how nutrient availability interacts with C uptake in tropical forests.本数据集包含采自法属圭亚那两处热带雨林的两项为期三年大型施肥实验的光合能力垂直剖面数据，以及叶片氮（N）、磷（P）浓度等关键叶片性状数据。该数据集为进一步优化热带森林光合过程中氮、磷及其他叶片养分的作用模型表征提供了独一无二的信息支撑。为进一步推动本数据集在综合研究与模型构建中的应用，我们同步提供了包含重要土壤属性与养分数据在内的详尽辅助数据集，并配套对应叶片观测数据。鉴于环境驱动因子是深化碳（C）-养分循环互作认知的核心要素，本综合数据集将有助于进一步阐明热带森林中养分有效性与碳吸收之间的相互作用机制。
