However, still there are few long-term studies that relate these organisms with application of organic residues in the soil. This study aimed to evaluate, in two cycles of culture of maize, the effects of the application of different doses and types of swine wastewater (ARS) combined or not with mineral fertilization on the edaphic meso and macrofauna. Four doses (0, 100, 200, 300 m3 ha-1) of ARS, treated in anaerobic digester in the first year of study and raw waste in the second year, associated or not with mineral fertilization were applied in two cycles of culture of maize totaling 24 experimental plots, being 12 using mineral fertilizer. Pit-fall traps were installed in each of the plots to be sampled soil fauna and the results were evaluated by multivariate statistical techniques (NMS and Per-MANOVA). The application of ARS both raw waste as treated in anaerobic digester and mineral fertilizacion did not influence soil fauna. Chemical soil parameters differed the edaphic meso and macrofauna only between the years / A utilização da fauna edáfica como bioindicadora de alterações antrópicas e ambientais vem crescendo nos últimos anos. No entanto, ainda são poucos os estudos à longo prazo que relacionam esses organismos com aplicação de resíduos orgânicos no solo. O objetivo desse trabalho foi avaliar, em dois ciclos da cultura do milho, os efeitos da aplicação de diferentes doses e tipos de águas residuárias da suinocultura (ARS) combinadas ou não com adubação mineral sobre a meso e macrofauna de solo. Quatro doses (0, 100, 200, 300 m3 ha-1) de ARS, tratada em biodigestor no primeiro ano de estudo e bruta no segundo ano, associadas ou não com adubação mineral foram aplicadas em dois ciclos da cultura de milho totalizando 24 parcelas experimentais, sendo 12 com utilização de adubação mineral. Armadilhas de queda foram instaladas em cada uma das parcelas para amostrar a fauna edáfica, sendo os resultados encontrados avaliados por técnicas de estatística multivariada (NMS e Per-MANOVA). A adição de ARS tanto bruta quanto tratada em biodigestor e de adubação mineral não influenciou a fauna de solo. Os parâmetros químicos do solo diferenciaram a meso e macrofauna edáfica somente entre os anos

Rapid urbanization and population growth have represented a great challenge to water resources management, since wastewater generated in urban areas forms a non-conventional source, wastewater reuse is being recognized as a sustainable water management approach. This study focuses on with the potential and practibility of implementing wastewater reuse techniques in Izmir region, especially with the aim to use treated wastewater and nutrient for agriculture. To this end, qualititative and quantitative agricultural water demand were considered. This thesis introduces a wastewater reuse planning model and optimization method with an emphasis on the wastewater treatment technology used as well as the agricultural demand in the area of the study. The model was developed with considerations over water quality, wastewater treatment and discharge. The objective of the model is to upgrade existing wastewater treatment plants or to design new treatment plants in regard to reuse wastewater in agriculture. The model is also capable of comparing treatment technologies from the point of design and cost. Three case studies were represented so as to demonstrate the modeling process and optimization studies for agricultural irrigation.
