Abstract

The objective of this study is to examine the relationship between soil properties and aggregate stability in oil palm plantations, influenced by varying distances from the Betara River. Soil analysis was conducted at the Soil Physics and Chemistry Laboratory, Faculty of Agriculture, Jambi University. Soil samples were collected using the Proportional Random Sampling method across plantation areas located at distances of 50 m, 500 m, 1000 m, and 1500 m from the river. The parameters observed included soil organic carbon content, soil moisture content, bulk density, total pore space, percentage of soil aggregates, and aggregate stability. Each treatment was replicated 15 times. To determine the physical properties of the soil and their relationship with river proximity, an independent sample t-test at a 5% significance level was used, followed by multiple linear regression analysis (Steel and Torrie, 1995). The results showed that the distances of 50 m and 500 m had similar values for organic matter content, bulk density, total pore space, moisture content, permeability, aggregate percentage, and aggregate stability. However, these values differed significantly from those observed at distances of 1000 m and 1500 m. Furthermore, multiple linear regression analysis revealed that organic carbon content and soil moisture were the dominant factors influencing aggregate stability, with a correlation coefficient (R) of 0.77. This study provides empirical evidence on how river proximity affects soil physical properties and aggregate stability in oil palm plantations. It highlights the importance of soil organic carbon and moisture content as key determinants of aggregate stability, offering valuable insights for land management strategies in riparian agricultural areas.

Abstract

Peatland characteristics are an important consideration in land management for agricultural development. As peat depth increases, nutrient availability and microbial activity tend to decline, while soil acidity (pH) increases. Thicker peat layers therefore have a significant influence on soil fertility. Oil palm (Elaeis guineensis Jacq.), originating from Nigeria in West Africa, is widely cultivated in Malaysia, Indonesia, Thailand, and Papua New Guinea. Oil palm plays a strategic role in national plantation development by creating employment opportunities, improving community welfare, and contributing substantially to national foreign exchange earnings, with Indonesia being one of the world’s major palm oil producers. This study was conducted at an oil palm plantation in Sungai Tawar Village, Geragai Subdistrict, East Tanjung Jabung Regency. The research was carried out over four months during 2024–2025. Soil analyses were performed at the Soil Laboratory, Faculty of Agriculture, Universitas Jambi. The study used a survey method with purposive random sampling. Observed parameters included groundwater table depth, soil organic carbon (C-organic), peat depth, macronutrient content (N, P, and K), and peat maturity. Observations were conducted on oil palm stands aged 11 and 16 years, with ten soil sampling replications for each plant age. Data interpretation to identify differences in soil depth and NPK content between oil palm ages was conducted using an independent t-test for C-organic content, N, P, and K levels, groundwater table depth, peat thickness, and peat maturity. The relationship between C-organic content and NPK was analyzed using simple linear regression. Results showed strong correlations between peat layer depth, groundwater level, and nitrogen availability, as well as between soil C-organic content and total nitrogen, available phosphorus, and total potassium across different oil palm ages.
