Mangroves have been recognized globally as one of the most carbon (C) rich ecosystems although they only occupy about 0.1% of the Earth’s land surface. Mangroves are regarded as an important C sink due to their waterlogged conditions, high sedimentation rates, high primary productivity, unique root structures, and anoxic soils resulting in low C decomposition rates. In recent decades, nitrogen (N) and phosphorus (P) loadings to mangroves have substantially increased due to intensified human activities and coastal development, but the effects on soil C, N and P cycling are unclear.
