Sub-Antarctic grass uptake of and growth on organic and inorganic N

These data form the basis of a study on whether sub-Antarctic Marion Island grasses acquire organic N, such as amino acids. The data included are from hydroponics experiments, testing whether the grasses acquire organic N intact and how organic versus inorganic N affects growth and biomass partitioning. There is also data from a small field experiment where 15N organic and inorganic N were provided to grasses along a gradient of iN:oN availability.

本数据集构成了对南极亚南极马里恩岛草地是否吸收有机氮（如氨基酸）的研究基础。其中包含的数据源自水培实验，旨在测试草地是否能够完整吸收有机氮，以及有机氮与无机氮对生长和生物量分配的影响。此外，还包括来自一个小型田间实验的数据，该实验中向草地提供了沿iN:oN可用性梯度的15N有机和无机氮。
