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Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use
Organic matter and size fractions from 65 deep core soil samples collected from 10 of the KBS LTER scaleup fields. Within each field we identified three topographicalpositions (DE-depression/footslope, SL-backslope, and SU-summit) and had 1-2 sampling sites at each position.
Samples were collected between April 27 and May 4 2010.
This datatable is part of the Deep core soil samples from KBS LTER Scaleup fields dataset. This dataset contains soil deep core data from 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.
