Use of loss-on-ignition to assess soil organic carbon in forest soils

Research output: Contribution to journalArticlepeer-review


Forest floor and mineral soils were collected from 169 conifer and hardwood forested plots across Minnesota, Wisconsin, and Michigan. Regression equations were developed between LOI and organic C for 20% of the samples (n-337) and LOI was then used to predict organic C on all of the samples. Results indicated that LOI is a good estimator of organic C in these soils, but that separate equations were needed for different soil strata. Percent organic C in forest floors was greater in conifer stands compared to hardwood (means of 35.1 and 30.1%, respectively).
