“…The literature shows a reduction of the total porosity of the soil with the application of wastewater, as observed by GONÇALVES et al (2010) that applying treated domestic wastewater in a Rhodic Hapludox, noted a decrease in porosity in almost any soil profile. JNAD et al (2001) explained the changes in porosity by applying wastewater by several factors: (a) the accumulation of Na + in suspension (b) deposition of organic material on the surface of the pores, and (c) increase of Na + in soil and dispersion/expansion of clays.…”

The study aimed to evaluate chemical, microbiological and hydro-physical changes of a Dystrophic Yellow Latosol, receiver of different levels of manipueira (cassava wastewater) application, in the cultivation of 'Terra Maranhão' banana. The experimental design was a randomized block with three replications in a factorial scheme 3 x 4, in which it was considered three soil depths and four levels of manipueira. It was evaluated the weighted mean diameter of the aggregate, the percentage of aggregation at different periods, soil density, particle density, porosity and soil saturated hydraulic conductivity, in addition to pH of P (mg dm -3), K (mg dm-3), Ca (cmolc dm-3), Mg (cmolc dm-3), Ca+Mg (cmolc dm-3), Al (cmolc dm-3), Na (cmolc dm -3), H+Al (cmolc dm-3), CEC (cmolc dm-3), V%, OM (g kg-1), soil microbial biomass (Ug Cg-1 dry soil), acid phosphatase (Ug PNP g-1 h-1). The use of manipueira influenced some physical characteristic of the soil, but it was not possible to specify the effect of increasing application dosage. Therefore, the application did not affect the biological indicators assessed in the soil or its pH. The use of manipueira as a fertilizer in the doses used in this study showed low increase of K, P, H+Al and Al in the soil and a good increase of Mg, Ca and Ca+Mg, Na, CEC and V%.

Fonseca (2001) and Souza et al (2005) reported substantial reductions in conventional fertilizers, eliminating indeed nitrogen fertilization.…”

Fertigation with wastewaters is a great option for reuse of effluents in agriculture. Domestic effluent can be reused after primary treatment, reducing treatment costs and pollution, also providing water and nutrients to crops. This work aimed to quantify the nutrients income in coffee crop fertigated with domestic sewage. Five treatments were used. T1 received only clean water, and treatments T2, T3, T4 e T5 received 180, 350, 480 Taubaté, v. 6, n. 3, p. 77-85, 2011 . (http://dx.doi.org/10.4136/ambi-agua.540) 78
