Early Successional Microplot Biomass (Sorted to species) — Main Cropping System Experiment (MCSE)

Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use

Plant biomass measured in response to long-term nitrogen fertilization and disturbance.
Biomass was sorted to species, The remaining biomass that was not identifiable was classified as un-sorted.

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

method the sampling protocol used. "sorted to species" means that the samples were sorted to species and any remaining material is classified as unsorted. "not_sorted" means that no attempt was made to sort and the material is just classified as unsorted.
disturbed has the plot been tilled annually (true or false)
fertilized has nitrogen fertilizer been applied to the plot (true or false)
biomass g m2 dry biomass measured per square meter g/m2
area sampled area that was sampled
