Abstract

One of the plantation commodities that is widely developed by the people of South Solok Regency is oil palm. The condition of plantation land dominated by the less fertile Oxisol soil order cause the quality of oil palm production is not optimal. This research aims to determine of pH, CEC, sulfur of soil and the sulfur nutrient uptake in oil palm on Oxisol owned by people at several different ages. This research was carried out at the people's oil palm plantations in Sangir Jujuan District, South Solok Regency, West Sumatra Province and at the Pathology, Entomology, Microbiology and Soil Science Laboratory, Faculty of Agriculture and Animal Science, Universitas Islam Negeri Sulthan Syarif Kasim Riau. Analysis of research samples was carried out at the WBS Education Laboratory in Padang City and this research was carried out from August to September 2024. This research uses a quantitative descriptive method by conducting a location survey and taking composite soil samples and leaf samples which are analyzed in the laboratory. The results of the study showed that the soil pH was in the range of 5.21 - 6.15, with soil CEC in the range of 7.25 - 20.11 cmolc/kg, soil sulfur in the range of 0.13% - 0.26% and the level of plant sulfur nutrient absorption in the range of 0.23 - 1.8 mg/100 g of plants. It was concluded that the pH of the research soil was in an acidic to slightly acidic condition, the CEC of the soil was low, the sulfur content of the soil and the level of sulfur nutrient absorption were deficient. Keywords: oil palm, Oxisol soil, sulfur nutrient uptake.
