Early Successional Microplot ANPP — Main Cropping System Experiment (MCSE)
This table is drawn from https://lter.kbs.msu.edu/datatables/154 and https://lter.kbs.msu.edu/datatables/685 by excluding surface litter and summing the biomass.
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
|Experiment:||Main Cropping System Experiment (MCSE)|
|Data available from:||July 1989 to September 2019|
|Core Areas||Primary Production,Disturbance|
|sample date||the date the plot was sampled|
|treatment||the field treatment that was sampled|
|replicate||the field replicate that was sampled|
|method||the sample method used. 'sorted to species' means that an attempt was made to sort the biomass to species and any remaining biomass was classified as unsorted. 'not_ sorted' indicates that no attempt was made to sort the biomass to species and all of the biomass was classified as unsorted.|
|disturbed||was the microplot tilled?|
|fertilized||was the microplot fertilized?|
|biomass g m2||the dry weight of the biomass in grams/meter squared||g/m2|
|area sampled||the area that was harvested for the sample in square meters||squaremeter|
