The Physical Properties of Soil in Palm Oil Agroforetrial System (Elaeis Guineensis Jacq.) with Aloes (Aquilaria Malacensis Lamk.) and In Palm Oil Monoculture System

Oil palm cultivation is generally carried out in monoculture. This has an impact on decreasing soil fertility, one of which the physical properties soil. One solutions that can be done to overcome this oil plants with agroforestry system. The purpose research was compare (Elaeis gueneensis Jacq.) and aloes (Aquilaria malacensis Lamk.) conducted Bukit Kemuning Village, Tapung Hulu District, Kampar Regency for 4 months from November – Februari 2020. Determination locations system monoculture using purposive sampling method. Soil samples were taken point: circle, leaf frond piles, harvest path circle repeated 6 times each land. observation parameters are several (topsoil depth, bulk density, particle total pore space, moisture content, water holding capacity, permeability, infiltration, resistance) C-organic. Data observations parameter analyzed statistically t test. results showed increased C-organic content improved selected (increase topsoil infiltration decrease density resistance).
