IRIS uses metal-oxide coatings on a polyvinyl chloride surface that, under anaerobic conditions, are removed to varying degrees over a 4-wk incubation period, during which time the user is not cognizant of the outcome. We document the viability of an alternative IRIS approach using clear-IRIS tubes, made from cellulose acetate butyrate, that can be continuously monitored in situ with a Wi-Fi–enabled video camera. This work shows that IRIS and clear-IRIS tubes are statistically equivalent. Manganese-oxide coated clear-IRIS tubes correlated well with IRIS tubes (r =.79) and ferrous-oxide had a high correlation (r =.97). A time-series analysis showed that rain-driven soil saturation induced IRIS metal-oxide reduction and controlled the rate. Clear-IRIS tubes enable remote sensing of metal-oxide removal over time. info:eu-repo/grantAgreement/ES/MINECO/PCI2018-092999 info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 2.932 2021 SOIL SCIENCE 23 / 39 = 0.59 2021 Q3 T2 0.763 2021 Soil Science 2021 Q1 4.3 2021 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Baldwin, Andrew H.
