Root Biomass from Cover Crops

Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use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 from the cover crops on treatments G2, G3 and G4. Measurements were started in 2013. The roots from individual cover crop plants (ex. rye) are excavated and the plant population in m2 is used to determine the BNPP in grams/meter2.

This datatable is part of the GLBRC Roots dataset. Below ground primary production for the GLBRC plots.
