Oil palm plantations in Babulu District are increasing because they have high economic value. Continuous tillage of the soil can cause nutrients in the soil to decrease and be supplemented by fertilizer application by farmers. This research was conducted with the aim of mapping the soil nutrient status (N, P, K, and pH) on oil palm land in Babulu District. This research was carried out by making a map of oil palm land use in 2024 in Babulu District. Furthermore, soil sampling was carried out using the purpose random sampling method in oil palm land in Babulu District and N-total, P-available, K-available, and pH analysis was carried out at the Soil Laboratory, Faculty of Agriculture, Mulawarman University. Nutrient status mapping was made using IDW (Inverse Distance Weighting) metode which is interpolation data based on the assumption that the value of unsampled points can be predicted as a weighted average of known values. The results of the study showed that the pH status of oil palm land in Babulu District was divided into sour and very sour. The N-total status in Babulu District is divided into very low, low, and medium. The P-available status in Babulu District is divided into very low, low, high, and very high. The K-available status in Babulu District is divided into medium, high, and very high.
