Deep Core Soil Fractions and Organic Matter — MCSE Scale-up Experiment
Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use
Soil sand and clay fractions, organic matter content, and bulk density of deep cores (0-90+ cm) collected April 27 – May 4, 2010 from 10 MCSE Scale-up Experiment fields and divided into five depth intervals. Within each field, three topographical positions were identified (DE=depression/footslope, SL=backslope, and SU=summit) and cores were taken from 1-2 sampling sites per position.
This datatable is part of the Deep Core Soil of the MCSE Scale-up Experiment dataset.
This dataset contains the results from deep cores collected in 2010 from 10 fields of the MCSE Scale-up Experiment and presented in Kravchenko, A. N., S. S. Snapp, and G. P. Robertson. 2017. Field-scale experiments reveal persistent yield gaps in low-input and organic cropping systems. Proceedings of the National Academy of Sciences 114:926-931. https://doi.org/10.1073/pnas.1612311114
