Soil Bacterial Structure and Composition in Pure and Mixed Plantations of Eucalyptus spp. and Leguminous Trees

  • Caio Tavora Coelho da Costa RachidEmail author


The soil harbors an incredibly high biodiversity, composed by many macro- and microorganisms, where bacteria are the most abundant and diverse ones. These tiny organisms are major players in nutrient cycling and are responsible for the maintenance of soil fertility and plant productivity by direct and indirect interactions. They are able to biologically fix nitrogen, produce phytohormones, increase nutrient bioavailability, protect from pathogens, and modulate plant responses to stress among many other functions. However, they are structured in very complex communities and controlled by many different factors and their responses to land use and management in forestry systems are still in the very beginning of our understanding. In this chapter, we present briefly the role of the bacterial community in forestry ecosystems, and how it responds to intercropping of Eucalyptus and Acacia. We show that there is a strong indication that the consortium of Eucalyptus with legume trees can integrate the soil bacterial community, increasing microbial activity and system stability with direct benefits to soil biogeochemistry. We also show that the bacterial biodiversity associated with trees can be explored in a biotechnological way, representing a green technology to optimize plant growth improving the sustainability of wood production.
