Plant attributes interact with fungal pathogens and nitrogen addition to drive soil enzymatic activities and their temporal variation

Nitrogen enrichment can alter soil communities and their functioning directly, via changes in nutrient availability and stoichiometry, or indirectly, by changing plant communities or the abundance of consumers. However, most studies have only focused on one of these potential drivers and we know little about the relative importance of the different mechanisms (changes in nutrient availability, in plant diversity or functional composition, or in consumer abundance) by which nitrogen enrichment affects soil functioning. In addition, soil functions could vary dramatically between seasons, however, they are typically measured only once during the peak growing season. We therefore know little about the drivers of intra-annual stability in soil functioning.
In this study, we measured activities of β-glucosidase and acid phosphatase, two extracellular enzymes that indicate soil functioning. We did so in a large grassland experiment which tested the effects, and relative importance, of nitrogen..., This is the data associated with the paper Nwe et al. \"Plant attributes interact with fungal pathogens and nitrogen addition to drive soil enzymatic activities and their temporal variation\" Functional Ecology.

氮富集可通过改变养分有效性与土壤化学计量比直接调控土壤群落及其功能，亦可通过改变植物群落结构或消费者丰度间接发挥调控作用。然而，绝大多数现有研究仅关注上述潜在驱动路径中的单一维度，我们对氮富集影响土壤功能的不同作用机制——包括养分有效性变化、植物多样性或功能组成变化、消费者丰度变化——的相对重要性仍知之甚少。此外，土壤功能存在显著的季节间波动，但现有研究通常仅在生长旺季开展单次测定，因此我们对土壤功能年内稳定性的驱动机制仍缺乏系统认知。

本研究针对表征土壤功能的两种胞外酶（extracellular enzymes）——β-葡萄糖苷酶（β-glucosidase）与酸性磷酸酶（acid phosphatase）的活性开展了测定，实验依托一项大型草地控制实验，旨在探究氮富集的作用效应及其相对重要性……本数据集关联发表于《Functional Ecology》的论文：Nwe 等题为"Plant attributes interact with fungal pathogens and nitrogen addition to drive soil enzymatic activities and their temporal variation"的研究，完整实验方法请参见该论文。
