Land application (LA) uses liquid waste from the palm oil industry to fertilize palm oil plants in palm oil plantation areas. This study aims to analyze the seepage distance of Palm Oil Mill Liquid Waste (LCPKS) from the LA channel on the physical and chemical properties of the Soil, as well as compare productivity between land given and those not given LCPKS. The research was conducted at PTPN V Artificial Sei Garden for three months, from January to March 2021; sampling was conducted on land granted by LA and NLA. LA land was taken at distances of 1 m (LA1), 2 m (LA2) and 3 m (LA3) from the LCPKS application channel with depths of 0-30 cm and 30-60 cm, which were taken zigzag three times and then analyzed in the laboratory. The physical properties of the Soil, soil chemistry and productivity obtained are intact soil extraction (bulk density, permeability, moisture content and porosity) and non-whole soil extraction (cation exchange capacity, C-Organic, N, P, K). The data obtained were analyzed using the ANOVA test and BNT test. The results showed that the closer to the flatbed, the better the physical and chemical properties of the Soil, thus affecting bulk density, permeability, moisture content, porosity, cation exchange capacity (CEC), C-Organic, Total N, P available, K available, pH, Na, Ca, and Mg and productivity on land given LCPKS is higher than not given.
