Plant Community and Ecosystem Responses to Long-term Fertilization & Disturbance at the Kellogg Biological Station, Hickory Corners, MI (1989 to 2012)

Dataset Abstract This work is part of the long-term sampling and monitoring of successional dynamics in abandoned fields – and responses to N-fertilization. Data from this research has been, and will continue to, contribute to LTER cross-site analysis of plant community dynamics, diversity-productivity, and responses to fertilization and disturbance.N-fertilized and tilled (disturbed) microplots are located in the NW corner of all treatment 7 (early successional communities) on the LTER main site. Experimental treatments are:
1) Nitrogen addition vs. no nitrogen addition and 2) Annual disturbance vs. undisturbed original data source http://lter.kbs.msu.edu/datasets/60

数据集摘要
本研究属于弃耕农田群落演替动态及氮施肥响应的长期采样监测工作的一部分。本研究产生的数据目前已，并将持续为LTER（Long-Term Ecological Research，长期生态研究计划）的跨站点分析提供支撑，该分析涵盖植物群落动态、多样性-生产力关系以及施肥与干扰响应等研究方向。
施氮并经翻耕（干扰）的微样地（microplots）设置于LTER主实验场地所有7号处理组（早期演替群落）的西北角区域。
实验处理设置为两类：1）氮添加与无氮添加；2）年度干扰与未干扰处理。
