decreased WIth IncreasIng Iron ComplexIng Index. PAtterns In Molecular PrOfiles IndicAted Dom In Paddy Soils To Become More RecalcItrAnt At Higher Soil C/n rAtio And Higher Soil Ph. furTherMore, PlAnt-derived polyPh.nols And Pyrogenic Dom Were retaIned Favorably By Iron And The ChemodiversIty Of Dom In Paddy Soil Increased WIth IncreasIng Soil C/n rAtios. These Results Provide Novel InFormAtion regardIng Dom Characteristics At a Molecular Level And Will InForm Better Global MAnagement Of Soil Carbon In Paddy Soil EcosysteMs Global. 2) Through The applicAtion Of Ft-icr-Ms, The ChemodiversIty Of Dom In Soil Subjected To Long-term OrgAnic Carbon And InOrgAnic Fertilizer Amendments Was Established. In Parallel, Bcc Was Assessed. Through This Coupled Approach It Was Established.thAt sustaIned OrgAnic Carbon Amendment Resulted In: SignificAntly (p < 0.05) Increased Total Carbon And Total nItrogen Reservoirs In Soil, Dom PrOfiles Of greAter ChemodiversIty, And Emergence Of RecalcItrAnt Dom Moieties (H/c < 1.5). In Contrast, Carbon And nItrogen Reservoirs In Soil Subjected To sustaIned InOrgAnic Fertilizer applicAtion Were Unaltered, While Soil OrgAnic Carbon ChemodiversIty Was Observed To Shift To Less RecalcItrAnt Dom Moieties (H/c rAtio > 1.5 And O/c rAtios < 0.5). furTherMore, sustaIned OrgAnic Carbon Amendment Shaped Bcc To a eutroPh.c stAte While Long-term Chemical fertilizAtion Directed The Bcc Towards An oligotroPh.c stAte. Higher connectivIty And Network complexIty Were Observed In OrgAnic Carbon Amended Soils. Dom-Bcc Network Analysis, IndicAtIng thAt Soil Microbes Had More Interaction WIth Dom Molecules followIng sustaIned OrgAnic mAtter Input. These Results Highlight The Potential For OrgAnic Carbon Amendments To Not Only Build Soil Carbon sTocks And Increase Their Resilience, But To Also Improve The Functional stAte Of Soil Microbial communIties.
