“…In addition, cover crops be able to improve the nitrogen cycle due to increases in pH, thus potentially minimizing the need for acid-forming nitrogen fertilizers in soils, which tends to decrease soil pH (Farzadfar & Congreves, 2022;Gambart et al, 2020;Kumawat et al, 2022).…”

Objective: The aim of this study was to analyze the physical and chemical properties of soil under Nephrolepis biserrata as a ground cover crop in oil palm plantations on Ultisols, Spodosols, and Histosols. Theoretical Framework: The research design comprehensively outlines the procedures for conducting the study, including data sources, collection methods, and analysis techniques, ensuring clarity in describing variables and facilitating effective data collection and analysis. Method: The study design used a splitplot with the main plot on soil types (Ultisols, Spodosols, Histosols) and subplots on cover crop conditions (without cover crop, N. biserrata, various cover crops) covering an area of 180 ha. Results: The research findings demonstrate that the use of cover crops significantly improves both the physical and chemical properties of soil in oil palm plantations. Notably, cover crops effectively enhance various chemical properties, such as pH, organic carbon, total nitrogen, phosphorus, and exchangeable cations, across different soil types. Even in Histosols with naturally high nutrient levels, implementing cover crops yields substantial benefits, particularly in pH improvement and nutrient enrichment. Research Implications: N. biserrata demonstrated better results compared to different cover crops. However, it's crucial to carefully select appropriate cover crops to improve soil quality and support the growth of oil palm plantations, considering the specific soil type. Originality/Value: This research, focusing on the physical and chemical properties of soil under N. biserrata in Indonesian oil palm plantations, serves as a valuable reference for companies seeking to select the most suitable ground cover plants tailored to their soil types.
