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Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use

Compilation of crop biomass, cover crop and non-crop biomass of MCSE Treatments 1-4 and 6-8 at the LTER Main Site to provide a consolidated view of the annual biomass production of the herbaceous cropping systems. The herbaceous understory (non-crop biomass) of the Poplar treatment (T5) and the Mid-successional (TSF) site is also included. Plant biomass is listed for the "Whole" aboveground plant material for each species; for crop species, the biomass of "Seed" and/or "Stover" may also be included.

For this table, “Surface Litter” is removed from the non-crop biomass. ‘Standing Dead’ is included and represents the biomass of rooted dead plants that cannot be identified to species; it may also include plant scraps that could not be identified after sorting.

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.
