Guide Explains Measuring Soil Organic Carbon

Iowa State University Extension and Outreach published a new, four-page guide, Measuring Soil Organic Carbon: A Crucial Iowa Resource, to help landowners and others better understand the importance of soil organic carbon and how to measure it. The free online publication contains photos and graphics that show how testing is done and at what depth. The publication also explains that soil organic carbon is closely related to soil organic matter, but the two are measured differently.
