Central Mississippi River Basin LTAR Dataset: NFARM, Inorganic N, & C Production, 2016-2018

posted on 2023-11-30, 09:47 authored by Julie N. Weitzman, Peter M. Groffman

In situ denitrification rates in intact soil cores from the Central Mississippi River Basin (CMRB) LTAR site in MO quantified by directly measuring dinitrogen (N2) and nitrous oxide (N2O) production via the Nitrogen-Free Air Recirculation Method (N-FARM) from 2016-2018. 10-day laboratory incubations provided estimates of ancillary soil data, including microbial respiration and potential net N mineralization and nitrification.
