Project Description

Project Title:  View help for Project Title Central Mississippi River Basin LTAR Dataset: NFARM, Inorganic N, & C Production, 2016-2018
Summary:  View help for Summary 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.
