Land use management and land cover selection are crucial aspects of the principles of sustainable peatland management. Management of peatlands can significantly impact the lives of local communities and threaten their food security. Therefore, this study aims to compare the characteristics of peatlands based on land management practices in the Klampangan. The chemical properties of the soil under various management practices were evaluated and will be used for multiple considerations in the sustainable utilization of peatlands in the future. This study used a purposive sampling method by composite soil samples from depths of 0-60 cm to analyze the availability and stock of nutrients (i.e., pH H2O, pH KCl, organic C, total N, available P, exchangeable K, Ca, Mg, and Capacity Exchange Cation (CEC). The nutrient availability data were then processed using an ANOVA analysis and further tested with Duncan's test at a significance level of p < 0.05. The results showed that agroforestry land use corn (AJ) and chili (AC) on peatlands is a potential land use for maintaining and providing nutrients. The availability of nutrients did not differ significantly (p > 0.05) from monoculture/intensive cropland use. The availability of P was 5.1-5.8 times higher in agroforestry (AJ and AC) compared to DFM land use. The availability of K, Mg, and CEC bases tended to differ significantly (p < 0.05) in agroforestry land use, which also affected nutrient stocks. Correlation results showed that organic C played the most significant role (r = 0.6) in increasing CEC.
