Grazing and silvopastoral systems offer a productive strategy for ameliorating sodic soils by increasing soil organic carbon (SOC) and total nitrogen (tN) availability. This study evaluated cattle production alternatives over a 6-year period to enhance SOC and tN content at different soil depths. We also assessed mineral-associated organic carbon (AOC) and particulate organic carbon (POC) fractions to understand SOC dynamics. The experiment covered 9 hectares each for silvopastoral and grazing systems, both cultivated with Chloris gayana cv Epica INTA-Pemán. Neltuma alba (syn. Prosopis alba) trees were planted in 1998 in the silvopastoral area. The treatments applied were: 1) Pure Pasture (PP), 2) Silvopastoral System Under Tree Canopy (SPS-UC), and 3) Silvopastoral System Between Tree Canopies (SPS-BC). Statistical analyses focused on the significance of treatment, time, and their interaction on SOC, POC, AOC, and tN across four measurement points over the 6-year period. Differences were observed in the distribution of SOC, POC, AOC, and tN between PP and SPS. SPS-BC exhibited the lowest values for SOC and tN. Both PP and SPS-UC gained SOC within the first 50 cm of soil depth, attributed to increased AOC levels. The results sustain the potential of the silvopatoral system as a practice to restore and improve soils with sodic limitation. These findings highlight the need for extensive research to assess how diverse tree configurations influence SOC and tN dynamics, enhancing land management practices for carbon and nitrogen sequestration in sodic soils.
