Changes in soil organic carbon after burning in a forest-savanna edge

open access: yesActa Agronómica, 2017
Soils are one of the largest terrestrial pools of carbon, yet there is still little understanding of spatial variability for ecosystems in the tropics. Fire plays an important role in neotropical savannas ecosystems and significantly contribute to global
