ABSTRACT
The study was carried out in a greenhouse with the objective of evaluating the tolerance of seedling of arboreal species cultivated in saline-sodic soil. The soil after drying and sieving was homogenized and placed in 2U capacity pots . The experiment involved 5 species, 2 amendment (sulphuric acid) levels and 3 repetitions, totalizing 30 pots, the treatments corresponding to the omission and presence of sulphuric acid (2.4ml.vaso-1). The cultivated species were: Prosopis juliflora, Leucaena leucocephala, Mimosa caesalpiniifolia, Caesalpinia ferrea and Enterolobium contorsiliquum. 50 days after germination it was verified that the algaroba and the tamboril presented larger growths of the aerial part and that the application of the sulphuric acid in the soil accentuated this result.
