The experiment was initiated in 2005 in a degraded and compacted area in which native species of Atlantic Forest were planted. The treatments applied were: 2.5, 5, 10, 15 and 20 t ha-1 of raw sewage sludge supplemented with K; conventional mineral fertilization; dose of K used as a supplement to the sludge, compared to a control treatment. The studied species are three pioneers, four secondary and three climax and all responded positively to application of sewage sludge, especially for the treatments with the highest doses.
