ANDHES PRANATA. Correlation Between Soil Respiration, Organic Carbon, And Soil Reaction In Oil Palm Plantations With Interrow Seedling Planting System (ISP) and Natural Vegetation Interrow (NVI) (Supervised by NUNI GOFAR). Oil palm plantations require proper inter-row management to maintain soil quality and ensure sustainable production. Inter-row management systems such as Interrow Seedling Planting (ISP) and Natural Vegetation Interrow (NVI) are presumed to have different effects on soil biological and chemical properties, particularly soil respiration, organic carbon (C-organic) content, and soil reaction (pH). This study aimed to analyze differences in soil respiration, C-organic, and soil pH between the ISP and NVI inter-row systems, as well as to examine the relationships between soil respiration and C-organic and soil pH. The research was conducted in a four-year old oil palm plantation through soil sampling and laboratory analysis, with data analyzed using the Independent Sample t-test and correlation and regression analyses. The results showed that soil respiration in the NVI system tended to be higher than in the ISP system; however, the difference was not statistically significant. Soil C-organic content in the NVI system was significantly higher than in the ISP system, indicating the role of natural vegetation in enhancing soil organic matter accumulation. Similarly, soil pH (H₂O) values also showed significant differences between the two inter-row systems. Relationship analysis revealed that soil respiration had a positive but weak and statistically insignificant relationship with C-organic and soil pH, both partially and jointly. This indicates that soil respiration is more strongly influenced by other factors not examined in this study, such as soil moisture, temperature, microbial activity, and the availability of readily decomposable substrates. Overall, the NVI system has the potential to maintain better soil quality through increased C-organic content, although it does not result in a significant increase in soil respiration. Keywords: ISP, NVI, oil palm, organic carbon, soil pH, soil respiration.
