The current ecological value has become a global trend that can be used as a reference in conservation. Soil is one of the parameters of the ecological value that stores organic matter (SOM) consists of organic elements C, N, P, and K contributing to the biogeochemical cycle. The purpose of this study is to determine the ecological value of soil organic matter in Mandala customary forests that is managed by using awiq-awiq. Data on soil organic matter content was carried out in the customary forests of Mandala, Bayan, West Nusa Tenggara, Indonesia. Soil samples taken at five points based on the height of 310-350 masl. Measurements were carried out directly and indirectly, using soil physical and chemical laboratory tests. Lab test results were then analysed using a cost-based approach to determine their ecological value. The results showed ecological values based on C, N, P and K (SOM) content of land contributed around 5609.74 USD / ha or 78,990,748, 9 IDR / ha and 5830.82 USD / ha or 82,103,776.4 IDR / ha. This value is an award given to Mandala customary forests in protecting SOM to maintain a biogeochemical cycle in forest ecosystems. However, it’s protection requires sustainable forest management.
