![]() Thermal analysis (differential scanning calorimetry (DSC) and thermogravimetry (TGA)) and nuclear magnetic resonance (solid state 13C CPMASS and NMR and 31P-NMR) spectroscopy have been applied to partially decomposed forest floor and soils of pure acacia and eucalypt, and mixed-species acacia-eucalypt stands. In the present study, OM quality and P forms in forest floor and soil were investigated to get more insight on the C and P dynamics useful to sustainable management of forest plantations. In spite of this, the relationship between SOM quality, C and other nutrient dynamics are not well understood. Therefore, SOM stability might play a crucial role in regulating soil-plant processes. In tropical environments, most of the nutrient processes are determined by the high rates of organic matter (OM) mineralization. However, some indicators suggest a perturbation in SOM and P dynamics might affect the sustainability of the system in the medium and long term. Eucalypt trees were expected to benefit from N 2 fixed by acacia. Acacia was introduced in eucalypt plantations established in the Congolese coastal plains to improve soil fertility and tree growth. Land-use change and forest management may alter soil organic matter (SOM) and nutrient dynamics, due in part to alterations in litter input and quality. ![]()
