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Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use

Biomass of non-crop species during the growing season and at peak biomass in MCSE Treatments 1-5, 7, and 8 at the LTER Main Site and at the Mid-successional (TSF) site to examine temporal distribution of species and biomass. Includes two harvests in 1990, 1992,1995, and 1996 for all treatments and four harvests in 1994 for Treatment 7 only.

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.
