Root biomass on T5 — 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Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use

Root biomass was sampled in 2014 on the LTER poplar trees to investigate their root distribution with depth. Three cores were taken. Core 1 was within 20 cm of the tree, Core 2 was taken half way between the trees and core 3 was taken halfway between core 1 and core 3. Each core was split into four depths and the roots were separated from the soil.

This datatable is part of the Belowground Biomass on the Main Cropping System Experiment dataset.

Belowground Biomass samples on the MSCE are infrequent due to the high labor costs.
