Abstract

The selection of cover crops is crucial in agricultural practices to improve soil quality and plant productivity. This research aims to analyze the effects of soil cover vegetation and liquid organic fertilizer (LOF) on soil organic carbon, soil respiration, and soil moisture. The research was conducted on a smallholder plantation in Kandangan Village, Laut Tador District, Batubara Regency, from April to September 2024. The method used was a factorial Randomized Block Design (RBD) with two factors: vegetation of soil cover (vegetated, bare, and planted with pintoi beans) and LOF type (from cow feces and cow urine). Data were analyzed using ANOVA with SPSS software version. 27. Differences in vegetation and the use of LOC cow manure affected soil organic carbon and soil respiration, but did not affect soil moisture. Pintoi bean vegetated fields increased soil organic carbon more than natural vegetation/grass. In contrast, soil respiration was higher in natural and grass-vegetated areas than in pintoi bean-vegetated areas, indicating a higher vegetation density that contributed more CO2. The interaction of vegetation and LOF influenced soil organic carbon, which was highest in the pintoi bean vegetated land irrigated with cow urine LOF, while soil respiration was higher in the grass vegetated land irrigated with cow urine LOF. Cow urine LOF is better at increasing soil biological activity.
