Resumo: With the objective of evaluating the relevance of wastewater use in irrigation, a experiment in pots with Lolium multiflorum Lam. was carried out. The soil used (cambisoil) was acid and poor in organic matter. The wastewater used in irrigation was treated by an activated sludge process. Is was observed that wastewater used had significant increases in the yields, without really affecting its quality. But its application did not avoid neither fertilization with nitrogen, phosphorus and potassium nor liming. As far as the soil characteristics analysed after the experiment are concerned, there are several which can be considered more relevant to its fertility. Wastewater increased the electrical conductivity, nitrates, boron, magnesium and sodium levels, wheres the potassium level decreased. Wastewater dilution decreased M.O. and exchangeable Na level in the soil.
