Measurements of height and diameter of tree species were made for 12 months. In addition, dam water samples were collected and the following parameters were analyzed: pH, conductivity, total phosphorus and heavy metals. In July and December of 2014, turbidity, color, biochemical oxygen demand (BOD) and dissolved oxygen (DO) analyzes were made. Physico-chemical analyses of soil were also carried out. Monitoring carried out from September 2013 to August 2014 showed some plants with good response in relation to the use of green manures, but others showed high mortality during the study, as the pequi. The competition between alien and native was reduced, which increased overall survival. Elements such as manganese showed no significant difference in all treatments during evaluation’s period. Macro and micropores values were similar, but for texture, the area showed some differences. For penetration resistance tests (PR) made in an area with and without green manure, the largest PR values were found in the one without legumes species. Parameters such as electric conductivity were stable during the 12 months of study. The results for DO and BOD are outside the recommended by the Resolution 357 of the National Environmental Council.</p><p></p>
