Indonesia's peatlands cover approximately 24.67 million hectares, storing large carbon reserves but having low fertility and acidic properties. In Perigi Village, two rice cultivation methods are applied: mounding (tapak timbun) and sonor rice farming. Both have advantages and disadvantages in supporting soil fertility and rice productivity. This study aimed to evaluate the nutrient status of peat soils under two different land-use systems: mounding (tapak timbun) and sonor rice cultivation, and to compare their effects on soil fertility levels. Peatlands are characterized by low fertility, high acidity, and nutrient limitations, thus requiring adaptive management practices to improve agricultural productivity while preserving ecosystem sustainability. The results revealed that all land-use systems exhibited highly acidic soils (pH 3.28–3.42), potentially limiting nutrient availability to plants. Total N content was highest in conventional rice cultivation (1.97%), followed by mounding (1.80%) and lowest in sonor (1.57%). Available P was highest under the sonor system (31.60 ppm), whereas exchangeable K was highest in mounding plots (0.96 cmol.kg⁻¹). These findings indicate that land-use practices significantly affect peat soil nutrient status, although soil acidity remains similar across methods. In conclusion, each system demonstrated advantages for specific nutrients: conventional rice cultivation improved N, sonor enhanced P availability, and mounding increased K levels. These results highlight the importance of combining cultivation techniques with appropriate soil amendments and organic fertilization to improve peatland fertility and support sustainable local rice production. Keywords : Peat soil, nutrient status, mounding, sonor rice cultivation.
