“…Bedbabis et al (2010) analyzed the effects of irrigation with treated effluents along 2 years in a sandy soil cultivated with olive trees in Tunisia and observed that the application of wastewater promoted greater accumulation of Mn and Zn in the soil, compared with the management with good water quality. Lado et al (2012), however, report that soils with similar texture irrigated with secondary effluents for 7 years showed lower Fe contents and Cu and Zn contents similar to those observed under the application of freshwater.…”

“…Great emphasis has been given to the reuse of organic and inorganic nutrients present in wastewaters for the fertilization of crops, which has allowed partially substituting, or even eliminating, the need for conventional fertilization. Many reports in the literature associate the practice of agricultural reuse with increments in crop yields (Leal et al, 2009a), adequate plant nutrition (Bedbabis et al, 2010) and beneficial alterations in soil physical-chemical characteristics, such as increase in fertility (Gwenzi & Munondo, 2008;Bame et al, 2014), reduction of acidity (Leal et al, 2009b;Tarchouna et al, 2010), increment in the contents of organic matter (Rusan et al, 2007;Xu et al, 2010) and improvement in particle aggregation.…”

The objective of this research was to investigate the effects of irrigation with treated wastewater and nitrogen (N) fertilization on the chemical characteristics of a Haplustalf soil cultivated with cotton. An experiment was conducted in a greenhouse in a completely randomized design with four replicates, and arranged in a 5 x 4 factorial. Five doses of N fertilization (0, 45, 90, 135 and 180 kg ha-1) and four sources of irrigation water (freshwater, wastewater treated by an anaerobic reactor, wastewater treated by an anaerobic reactor and post-treated by intermittent sand filter in series, wastewater treated in a septic tank and post-treated by an intermittent sand filter) were tested. Irrigation was daily performed from July 2011 to January 2012 according to the water demand of cotton resulting in a water depth of 620 mm. It was found that, compared with the conventional management with freshwater irrigation, treated wastewater provides greater accumulation of micronutrient, potassium and sodium in the soil, increasing the risk of sodification in irrigated areas.

“…O reúso controlado de efluentes é uma realidade em países como Israel, Espanha, Portugal, Itália, Tunísia e França, dentre outros, tornando-se uma substituição de fonte que disponibiliza água de qualidade para atividades essenciais da sociedade. O reúso não potável para fins agrícolas é uma prática de reciclagem de água e nutrientes que contribui para a elevação da produção agrícola e para o saneamento ambiental, especialmente em regiões semiáridas, onde o reúso de efluentes na agricultura pode ser uma solução sustentável para a escassez de água (BEDBABIS et al, 2010).…”

*autor correspondente m aqueiroz@pe.senai.br RESUMO: O reúso de água na irrigação no Brasil está deixando de ser uma alternativa e se tornando uma necessidade, devido aos baixos índices pluviométricos observados nos últimos anos. Este trabalho objetivou avaliar o impacto do reúso de efluente doméstico tratado sobre o sistema solo-planta, como única fonte de nutrientes na adubação de cobertura para a produção do tomate, aplicado por gotejamento. Adotou-se delineamento experimental em blocos casualizados, em esquema de parcelas subdivididas, tendo nas parcelas água do Rio São Francisco associada a fertilização química (T1), efluente clorado (T2) e o efluente (T3), além das cultivares de tomate IPA 7 e IPA 14-7 nas subparcelas. Ao início e final do experimento foram realizadas análises químicas do solo, visando recomendação da adubação e avaliação dos impactos do reúso sobre as propriedades químicas do solo. Foram realizadas, ainda, análises microbiológicas, para identificar a presença de coliformes totais e termotolerantes, além de Salmonellas sp., no solo, e coliformes totais e Salmonelas sp., nos frutos. As variáveis analisadas foram a produção total de tomate, teor de sólidos solúveis e pH dos frutos. Os resultados foram submetidos à análise de variância e teste de médias, adotando-se Tukey a 5% de probabilidade. Os resultados permitiram concluir que não houve contaminação microbiológica no solo e nos frutos, tendo o reúso de efluente elevado a produtividade do tomate. PALAVRAS-CHAVE:Lycopersicon esculentum, reúso de água, contaminantes. ABSTRACT: The reuse water for irrigation in Brazil is

“…Non-signifi cant injuries caused by salts and/or heavy metals were observed on the shoot growth of trees irrigated with wastewater irrigation. Application of wastewater irrigation in Tunisia significantly increased the concentration of N, P and K in the leaves, whereas heavy metals (Zn and Mn) showed a signifi cant increase only after the second year of irrigation (Bedbabis et al 2010a ). Irrigation with wastewater over 4 years did not affect free acidity, and specifi c ultraviolet absorbance on olive (Bedbabis et al 2010b ).…”

The need for irrigated agriculture is growing day by day and the largest water withdrawals from renewable water resources are for irrigation. In addition, the available water resources are decreasing and we need to use non-conventional water resources for irrigation due to looming water crisis (Raschid-Sally and Jayakody, Drivers and characteristics of wastewater agriculture in developing countries: results from a global assessment. International Water Management Institute, Colombo, 35p, (IWMI Research Report 127), 2008). However, the volume of treating and using wastewater is limited due to the lack of adequate data and knowledge and/or negative effects of improper wastewater management (i.e. use of untreated wastewater). A comprehensive evaluation of what has been done is necessary in order to explore wastewater irrigation and to avoid trial-and-error policies. Although a study of wastewater irrigation from crops, soil, groundwater, health, irrigation equipments, modern technologies, and other environmental aspects is useful, management studies in comparison with other aspects can help lead to more reliable and more extensive fi ndings and fi nally a better decision on using wastewater for irrigation. The chapter presents challenges and prospects that may help decision making for the use of wastewater in irrigation.
