The Impact of Implementing Agarwood Agroforestry System (Aquilaria malacensis Lamk.) on Soil Texture, Topsoil Depth, and Water Retention Capacity in Oil Palm Lands (Elaeis guineensis Jacq.)
Abstract
The impact of implementing an agroforestry system in oil palm plantations by integrating agarwood-producing plants (Aquilaria Malacensis Lamk.) with oil palm plants on the physical properties of the soil needs to be assessed. This study is crucial due to the shared land use by agarwood-producing and oil palm plants. The study aims to evaluate the effects of integrating agarwood-producing plants into oil palm plantations on soil physical properties, including soil texture, topsoil depth, and water retention capacity. The research was conducted from September 2024 to November 2024 in agroforestry land (1 ha) and monoculture land (1 ha) in Bukit Kemuning Village, Tapung Hulu Kampar - Riau. The study utilized survey methods and systematic sampling for soil sample collection. The findings indicated that the agroforestry system positively impacted soil physical properties, with improved soil texture (54.67% sandy clay), increased topsoil depth, and enhanced water retention capacity compared to oil palm monoculture land. This improvement can be attributed to the higher organic matter content resulting from the decomposition of agarwood plant litter. Therefore, the agroforestry system enhances soil fertility and promotes sustainable environmental management.
