Peatlands provide several ecosystem products and services, highlighting their capacity to mitigate climate change through carbon storage. In this sense, this study focused on evaluating the physical characteristics and carbon content in peat soils from the communities of Nuevo Saposoa and Patria Nueva located on the Ucayali River. We evaluated (i) the depth of peat, as well as the horizontal and vertical distribution of (ii) pH, (iii) the degree of decomposition, (iv) the apparent density, (v) the proportion of organic matter and carbon and (vi) the carbon stored (stock) in peat. The depth of peat in the study area varied between 19 and 210 cm. Saposoa swamp (AS) had the greatest depth with 132.1 ± 21.8 cm. The degree of decomposition and the apparent density of peat were characterized by increasing with greater depth of the peat profile in all sampled sites. Bulk density was highest in restinga Saposoa (RS, 0.3291 ± 0.0456 g/cm3). The proportion of organic matter and carbon also increased with peat profile depth in RS and Patria Nueva (PN). The pH of RS (5.3 ± 0.2) and PN (4.6 ± 0.1) peatlands increased from the edge to the center of the peatland. The highest carbon stock was measured in PN, followed by RS and AS: 499.0 ± 76.5, 425.9 ± 351.3 and 283.1 ± 52.7 t C/ha, respectively. In general, the soil carbon stock of peatlands increased with bulk density and peat depth. The results indicate associated with carbon storage may vary among peatlands and suggest the importance of detailed studies to improve carbon mapping and quantification in Amazonian peatlands.
