“…Other attributes, such as organic matter and nitrogen, also showed differences in this type of experiment; however the differences are dependent on concentrations in the TSE, the application period and the respective climatic and soil conditions. Garcia et al (2012), cultivating fertirrigated forages with TSE confirmed increases in the levels of phosphorus, potassium and base saturation, a fact that in the present study only occurred with potassium.…”

The use of treated sewage effluents (TSE) for irrigation purposes is a viable alternative for wastewater reuse and nutrient supply to the soil, which represent the two main environmental benefits. This work therefore evaluated the effect of the application of TSE on the quantity of nutrients added to the soil and changes in the chemical attributes of a Red-Yellow Latosol in the layer from 0.0 to 0.2 m cultivated with the bell pepper F1 Canary hybrid and surface drip irrigated. The experiment was carried out under field conditions from September 2015 to January 2016 in a randomized block statistical design with four replications, including the following treatments: river water, TSE, river water with base fertilization, TSE with base fertilization, TSE with cover fertilization, and TSE with cover and base fertilization. Irrigation of the bell pepper cultivation with TSE increased the level of potassium but did not affect the levels of phosphorus, organic matter and pH of the soil at the end of the growing cycle. The following amounts of nutrients were added to the soil by irrigation with TSE: 10 kg ha-1 of total nitrogen, 10 kg ha-1 of total potassium and 0.5 kg ha-1 of total phosphate. In general, TSE induced greater productivity of the peppers than those irrigated with river water, even when including mineral fertilization.

A disposição de efluente doméstico no sistema solo-planta pode minimizar os custos de produção em razão do aporte de água e nutrientes para as plantas, e reduzir o impacto ambiental nos corpos hídricos. Assim, o objetivo do presente estudo foi avaliar os efeitos da aplicação de doses crescentes de efluente doméstico tratado sobre os atributos químicos do solo e sobre a produção de matéria seca de plantas de milho. O experimento foi conduzido em casa de vegetação, localizada na Universidade Estadual de Maringá. O experimento foi arranjado em delineamento inteiramente casualizado, em esquema de parcelas subdivididas, com quatro repetições. Nas parcelas foram avaliadas cinco doses de efluente doméstico (0, 150, 300, 450 e 600 m3.ha-1) e na subparcela foram avaliadas cinco profundidades (0–0,05; 0,05–0,10; 0,10–0,20; 0,20–0,40; 0,40–0,60 m). O milho foi semeado nas unidades experimentais, e 15 dias após a emergência foram aplicados os tratamentos. Os resultados mostraram que a aplicação do efluente não influenciou os valores de pH, fósforo e potássio no solo; entretanto, a concentração de sódio aumentou. Em relação à produção de matéria seca, não se constatou efeito significativo com a aplicação das doses crescentes de efluente doméstico.

“…Nitrogen were found in concentrations of 17 to 35 mg L -1 , which is suitable for most crops grown in the study environment (RIBEIRO et al, 2012;ANDRADE FILHO et al, 2013). Higher concentrations were found in sewage treatment systems in the Brazilian Southeast region (Araras, SP; Alegre, ES; and Botucatu, SP), ranging from 45 to 77 mg L -1 , (GARCIA et al, 2012;PINTO et al, 2013;SOUZA et al, 2015).…”

Wastewater Use in Agriculture: Analytical Limits of Sewage for Impact Control in Brazil

et al. 2019

View full text Add to dashboard Cite

Water deficit is a current problem of global relevance. This is a problem in Brazil, especially in the Semiarid region, which undergoes severe droughts for much of the year. This requires the search for alternatives, such as the planned wastewater use, which is a successful alternative in developed countries that is applied for various purposes, including agriculture. However, despite the increasing growth of agriculture in Brazil, there are no established control and monitoring policies to minimize its impacts on the environment and human health. The country does not have specific legislation that defines wastewater quality parameters for domestic sewage. The objective of this work was to compile international guidelines and legislations that address this issue and compare them with the national normative resolutions for quality of wastewater and its different uses. The most relevant and locally applicable parameters described in these documents were listed, and the reference limits were defined by comparing them with those found in the scientific literature applied to the Brazilian context. This compilation represents the first step towards the incorporation of regulations for water reuse, having the Brazilian Semiarid region as a first test field, but with expandable application to different regions of the country.
