<![CDATA[Indonesia is an agrarian country with quite extensive land and a variety of soil types. The distribution of acidic mineral land in Indonesia covers an area of 102.8 million hectares. Mineral soil can be utilized as plantation areas, including oil palm plantations. This research aims to analyze the macro nutrient status in oil palm plantations and provide fertilization recommendations for oil palm crops in Labang Village, Belimbing District, Melawi Regency. The study uses survey methods and field sampling at depths of 0-30 cm with a diagonal system. Soil samples were taken from three locations, A, B, and C, and analyzed in the Soil Chemistry and Fertility Laboratory and the Soil Physics and Conservation Laboratory. The collected soil samples were analyzed for soil pH, organic carbon, total nitrogen, available phosphorus, exchangeable potassium, calcium, magnesium, sodium, cation exchange capacity (CEC), base saturation, and bulk density. The data were processed by comparing to criteria tables, then tabulated into soil fertility status criteria tables from PPT 1995. The macro nutrient status, including organic carbon, total nitrogen, available phosphorus, exchangeable potassium, calcium, magnesium, sodium, CEC, and base saturation, in sites A, B, and C varies with dominance of low to very low criteria. The fertilizer requirement recommendations for the research locations are as follows: Urea ranges from 2.35 to 2.66 kg per tree; SP-36 from 1.40 to 1.48 kg per tree; KCl from 5.01 to 5.41 kg per tree.
