The availability of nutrient elements that play a role in increasing paddy productivity, especially macro nutrients such as N, P, and K. The aim of this study is to determine the soil fertility status and provide fertilization recommendations for paddy cultivation in Veteran Jaya Village, Martapura Subdistrict, Ogan Komering Ulu Timur Regency. This study used a detailed survey method with a scale of 1:10,000 by taking soil samples at the research location at a depth of 0-30 cm. Twelve soil samples were taken, with each sample representing a 1 ha land area, and then the samples were taken to the laboratory for chemical analysis of soil properties. The observed soil chemical properties are soil pH, organic C, total N, available P, and available K. The results of soil pH analysis indicate acidic criteria ranging from 4.23 to 5.09. Soil organic carbon (C) has a very low to high criteria ranging from 0.85% to 3.15%. Total nitrogen (N) has a very low to low criteria ranging from 0.02% to 0.22%. Available phosphorus (P) has a very low to low criteria ranging from 1.70 mg kg⁻¹ to 11.62 mg kg⁻¹. Available potassium (K) has a low criteria ranging from 0.19 cmol kg⁻¹ to 0.39 cmol kg⁻¹. Based on the analysis results, NPK fertilization recommendations for paddy cultivation in the research location include Urea fertilizer with a dosage ranging from 147,34 to 234,30 kg ha⁻¹, SP-36 fertilizer ranging from 23,92 to 150,14 kg ha⁻¹, and KCl fertilizer ranging from 30,41 kg ha⁻¹. Keywords: Fertilizer, Nutrient, Rainfed.
