| dc.description | ABSTRACT: We assessed the impact of organic N sources on total organic carbon (TOC), particulate organic carbon (POC), and mineral-associated organic carbon (MAOC) pools in a Nitisol from Southern Brazil under contrasting soil tillage systems. The tillage systems were conventional tillage (CT) and no-tillage (NT). The tested N sources were: 140 kg N ha-1 (total N input) either as mineral fertilizer (urea; MIN), pig slurry (PS), anaerobically digested pig slurry (ADS) and composted pig slurry (CS), besides a control without fertilization (CTR). TOC stocks decreased by 1.0 and 5.1 Mg C ha-1 after two years of CT in both 0-5 and 0-30 cm soil layers, respectively. NT increased TOC stocks by 2.3 Mg C ha-1 at the soil surface and decrease by 1.7 Mg C ha-1 at the 0-30 cm soil layer. NT had higher POC and MAOC stocks than the CT soil. POC was a more sensitive pool than MAOC in response to soil tillage and fertilization practices. Long-term and continuous assessment of SOC pools is needed for evaluation of the impact of organic N sources for C sequestration in NT soil. | |
