Processes such as the construction of the Ilha Solteira Hydroelectric Plant resulted in several environmental problems, such as the fauna and flora species extinction, as well as contributed to climate change, subsoil / soil severe erosion and consequent water siltation. Conditions such as this requires a better alternative to occupation and, possible, to recovery, and then, to minimize negative impacts. To reverse such a process, interventions are needed through strategies such as revegetation and use of alternative sources of organic matter and symbiotic micro-organisms. Thus the aim of this study was to evaluate the deployment of jatropha on degraded soil and inoculated, that received macrophytes, ash (derived from burning bagasse from sugar cane) and hydrogel. The experiment was conducted at the Farm for Teaching, Research and Extension (FEPE), UNESP - Universidade Estadual Paulista, Ilha Solteira Campus, in Selvíria - MS, in an area with degraded soil, arising from construction of the Ilha Solteira Hydroelectric Plant. The experimental design was randomized blocks, each one occupying an area of 960 m2 (30 x 32m), comprising 16 rows with 10 plants per row, which on with 14 internal rows 8 plants per row. The design was a 2 x 2 x 4 factorial, ie 2 inoculation treatments (with and without preserved Cerrado soil containing soil microorganisms, including mycorrhizal fungi (AMF), 2 hydrogel treatments (with and without) and 4 residues treatments (macrophytes, ash, macrophytes+ash and control without residue), with 4 replications (blocks), and 5 evaluated plants per treatment, per replicates. Preserved Cerrado soil was used as source of micro- organisms, including FMA. The planting of Jatropha was held in December 2010 and, over 12 months. The subsoil were collected at a depth of 0-0.10 m. Evaluations were performed at 30, 120, 240 and 360 days after planting (DAP) for soil chemical properties, spore numbers, percentage of root ...
