Relationship between Soil Conservation Techniques, Topsoil Depth and Vegetation Density Growing in Oil Palm Plantation Areas in Plantation IV, Regional II, Marihat
Abstract
This study aimed to identify land conservation techniques and analyze the relationship between soil conservation techniques, topsoil depth, and weed density in coconut and palm oil plantations at PT Perkebunan Nusantara IV Marihat. The research was conducted in April–May 2026 using a descriptive method with a field survey approach. Samples were selected purposively based on the different conservation techniques applied to the land. Data were collected through field observations, measurements of topsoil depth, and analysis of weed vegetation using parameters such as density, frequency, dominance, important value, and the Summed Dominance Ratio (SDR). The results of the study show that the weed vegetation is dominated by Axonopus compressus, which has the highest SDR value of 0.55. Topsoil thickness ranges from 27 to 33 cm, with an average of 30 cm, indicating that the land is relatively suitable for coconut and palm oil growth. There is a relationship between vegetation density and topsoil thickness, where vegetation plays a role in covering the land, helping to reduce erosion and maintain land stability. Weed management should be selective, and sustainable land conservation practices are recommended to support productivity and ensure land sustainability.
