Abstract

Sugarcane expansion in native vegetation areas and pastures causes soil carbon stocks depletion. Furthermore, previous findings of this research show that soil structural stability decreases in the land use sequence native vegetation - pasture - sugarcane. The ultimate mechanisms by which land use change for sugarcane production accelerates soil organic matter (SOM) decomposition and deteriorates soil structure have not been well elucidated. We advanced the hypothesis that the soil (macro)biota activity loss control the decrease in soil structural stability and the C-depletion in sugarcane expansion areas. Thus, the main objective of this research internship abroad is to address the role of soil macrobiota in mediating shifts in structural stability and soil organic matter allocation in the land use change for sugarcane production. More specifically, this project proposes: (i) to quantify the impacts of the land use sequence native vegetation - pasture - sugarcane on total abundance, biomass, and taxonomical richness of the soil macrofauna as from a data set already obtained; (ii) explore the relationships between macrofauna parameters, soil structure and SOM allocation through multivariate statistical methods; (iii) to study the general ecosystem functions and understanding the role that each key functional group of soil organisms play in regulating pools of SOM. As an ultimate product of the research internship, scientific manuscripts will be prepared and submitted to high impact journals. (AU)
