Fine Root Productivity (BNPP) and Carbon and Nitrogen - Perennial Crops (G5-G10)

Fine root production estimated using root in-growth cores. To determine an approximate peak standing crop, two root in-growth cores were installed at the beginning of the growing season at each sampling location; one of them was collected mid-season and the other was collected at the end of the season. BNPP (fine root biomass to given depth) was measured as well as carbon and nitrogen. Calculated grams of carbon and nitrogen in fine roots by area is also given.

KBS BNPP is averaged by station here because KBS CN data were grouped by station. BNPP data by station are available for KBS at: http://lter.kbs.msu.edu/datatables/306

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