Abstract

Disturbance of native areas has a direct impact on soil organic matter (SOM) and related physical and chemical attributes, which directly affect soil quality and its capacity to provide ecosystem services. In Brazil, some researches regarding soil quality have been developed in the most traditional agricultural areas (e.g., south and central regions). However, in areas that have been under recent expansion (i.e., characterized by unique climate and soil aspects, such as in the case of MATOPIBA), there is still a great need to understand the effects of land management on ecosystem services. The main objective of this research internship is to assess the effects of the land-use change on soil quality, in Brazil's last agricultural frontier. Specifically, the main objectives of the work plan to be developed abroad are to: i) participate in the International Soil Biology Lab Skills Training Course; ii) identify the main soil attributes (chemical, physical and biological) related to soil functions in the MATOPIBA region; iii) integrate the collected data into a soil quality index (SQI). Soil sampling and analytical analyses have already been done (e.g. carbon stocks, fertility, chemical, and biological attributes). I have been invited by Wageningen University to participate in the International Soil Biology Lab Skills Training Course, which is focused on the assessment of the soil functions and its quality and to apply the acquired skills in the integration of our data into a SQI. The results obtained here will constitute a useful indicator for soil quality monitoring, and inform future decision-making associated with the expansion of Brazil's largest agricultural frontier.
