Early Successional Microplot Biomass - by Species

Plant biomass measured in response to long-term nitrogen fertilization and disturbance.

This datatable is part of the Plant Community and Ecosystem Responses to Long-term Fertilization & Disturbance dataset. 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
