Top Non-crop species by Biomass — 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Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use
This datatable is derived from KBS019-004 it includes the average species proportion and the treatment species proportion. The treatment species proportion is calculated by diving the total biomass of the species for the whole treatment by the total biomass for that treatment.
This table excludes standing dead biomass (which is part of the current year's biomass) and surface litter (which may not be part of the current year's biomas).
This datatable is part of the Primary Production of Herbaceous Systems of the Main Cropping System Experiment dataset.
This dataset contains the biomass data of herbaceous systems of the Main Cropping System Experiment (MCSE), including Treatments 1-4 and 6-8 at the LTER Main Site (since 1990) and the Mid-successional (TSF) site (since 1993). Included are the data collected at or near peak biomass to estimate aboveground net primary production (ANPP). Systems with multiple harvests or with peaks occurring at different times throughout the growing season may have multiple measurements per year. See the ANPP protocol for sampling and measurement methods of these treatments.
