Early Successional Microplot Biomass (Bulk samples) — 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Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use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.
Bulk biomass samples and surface litter was collected. In some years the spring burn did not leave any surface litter.
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
