1 RESUMO A escassez de agua no mundo motivada pelo rapido crescimento populacional, pela ausencia de uma politica efetiva de gerenciamento dos recursos hidricos e pela intensificacao das atividades produtivas tem motivado o desenvolvimento de praticas que viabilizem a diminuicao do consumo. O uso de agua residuaria na agricultura surge como uma alternativa viavel, visto que esta pratica diminui a captacao de aguas de boa qualidade para o consumo potavel, a contaminacao de corpos d´agua pela deposicao de esgotos, alem apresentar caracteristicas fertilizantes. O presente trabalho objetivou analisar as alteracoes quimicas de solo fertirrigado com agua residuaria cultivado com algodoeiro em regiao semiarida brasileira. Os experimentos foram desenvolvidos com esgoto urbano de lagoa de estabilizacao, em Mossoro-RN. O delineamento experimental adotado foi o de blocos casualizados com parcelas subdivididas, sendo que em nivel de parcelas foram testadas as diluicoes do efluente domestico [25% - T 1 , 50% - T 2 , 75% - T 3 e 100% de agua residuaria – T 4 e agua de abastecimento + adubacao mineral no solo – T 5 ] e as subparcelas constituiram-se de dois solos (Latossolo Vermelho Amarelo e Cambissolo). A aplicacao de agua residuaria de esgoto domestico provocou alteracoes quimicas no solo com textura mais argilosa (Cambissolo) e no latossolo apenas o calcio.  Todas as caracteristicas avaliadas no Cambissolo foram alteradas pelas proporcoes de agua residuaria, exceto o calcio.

CHEMICAL PROPERTIES OF SOIL FERTIGATED WITH URBAN SEWAGE IN THE SEMIARID BRAZILIAN REGION 2  ABSTRACT Water scarcity throughout the world driven by  rapid population growth, lack of an effective  management policy of water resources, and the growing production activities has fostered the development of practices which  make possible a decrease in  consumption. The use of wastewater in agriculture emerges as a viable alternative, as this practice reduces   the uptake of water of good quality for drinking consumption and the pollution of bodies of water by sewage  disposal. Moreover, it has fertilizing properties. In light of these considerations, the objective of this study was to analyze chemical characteristics of soil fertigated with urban sewage cultivated with cotton in the semiarid region of Brazil. The experiments were conducted with urban sewage from a  stabilization pond in Mossoro-RN. The experimental design was randomized blocks with split plots. Dilutions of wastewater reuse were tested in the plots [25% - T1, 50% - T2, 75% - T3,  100% of wastewater – T4, and water supply + mineral fertilizer in the soil  T5] and 2 soils (Oxisol and Cambisol) in the subplots.  The application of wastewater from sewage caused chemical changes in the soil  with   more clay texture (Cambisol), and calcium changes in the latosol soil.   All characteristics in the Cambisol soil   were altered  by the levels   of wastewater, except for the calcium. Keywords: environment, water reuse, sustainability.
