Cover Crop 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Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use

Aboveground biomass of cover crops in the MCSE Reduced Input (T3) and Biologically Based (T4) treatments at the LTER Main Site before their incorporation into soil. Cover crops are planted the preceding year and plowed under the next spring prior to planting corn or soybean. Winter wheat is planted immediately after the soybean harvest, so wheat years have no cover crop biomass data. See Related Tables for biomass of non-cover crop species in samples.

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.
