“…The increase in the pH-CaCl 2 of the soils treated with alkalinized sewage sludge ( Figure 2A) was consistent with previous studies using this type of sludge (Corrêa et al, 2007;Tamanini et al, 2008;Serrat et al, 2011) or other where: ER, element recovery (%); Czero, element content in soil without alkalinized sewage sludge application (mg kg ) (Dalpisol et al, 2017).…”

Although it is known that alkalinized sewage sludge raises the pH of acid soils, there is limited knowledge regarding its effects on other soil fertility indicators, such as P and K availability and soil organic C content. Thus, the goal of this study was to evaluate how the application of alkalinized sewage sludge affects the fertility of acid soil. Twenty sewage treatment plants were selected throughout Paraná State (Brazil), and samples of alkalinized sewage sludge and samples of the most representative agricultural soil of the region were collected (covering soils with medium, clayey or very clayey texture). Each soil was incubated for 60 days with doses of sewage sludge (0, 10, 20, 40, and 80 Mg ha -1 ) from its region and equivalent doses of limestone. The alkalinized sewage sludge was superior to limestone in the correction of soil acidity (pH, Al 3+ , and H + Al 3+ ) and P and Ca 2+ availability. The sludge also increased Mg 2+ availability in all soils, K + in seven soils and organic C in three soils. The very clayey soils (higher buffering capacity) supported higher sludge doses than did clayey and medium texture soils. The alkalinized sewage sludge application in acid soils proved to be an interesting alternative to recycling this type of waste, because it improved soil fertility and could reduce costs associated with soil management and crop fertilization.Index terms: Sanitation waste; liming; phosphorus recovery; nutrient source; organic matter. RESUMOEmbora seja conhecido a capacidade do lodo de esgoto alcalinizado em elevar o pH de solos ácidos, tem-se um limitado conhecimento sobre o efeito em outros indicadores da fertilidade do solo, como disponibilidade de P e K e, teor de C orgânico no solo. Assim, o objetivo do estudo foi avaliar como a aplicação de lodo de esgoto alcalinizado afeta a fertilidade de solos ácidos. Foram selecionadas vinte estações de tratamento de esgoto ao longo do Paraná (Brasil), onde foram coletadas amostras de lodo de esgoto alcalinizado e amostras do solo agrícola mais representativo da região (abrangendo solos com textura média, argilosa ou muito argilosa). Cada solo foi incubado por 60 dias com doses de lodo de esgoto (0, 10, 20, 40, ) da sua região e com doses equivalentes de calcário. O lodo de esgoto alcalinizado foi superior ao calcário na correção da acidez do solo (pH, Al 3+ e H+Al 3+ ) e na elevação da disponibilidade P e Ca 2+ . O lodo também aumentou a disponibilidade de Mg 2+ em todos os solos, K + em sete solos e C orgânico em três solos. Os solos muito argilosos (alta poder tampão) suportam maior dose de lodo em comparação aos solos de textura argilosa e média. A aplicação de lodo de esgoto alcalinizado em solos ácidos demonstrou ser uma interessante alternativa para reciclar esse tipo de resíduo, pois melhorou a fertilidade dos solos e pode vir a reduzir custos com manejo do solo e adubação das culturas.

“…Sewage sludge application to soils has been a well‐studied option for its final disposal as this residue acts as a soil conditioner and supplies nutrients for plants (Dalpisol et al., 2017; Laura et al., 2020). However, sewage sludge is frequently a source of metals that may enter the food chain and become the most critical long‐term hazard to humans and other living organisms (Feizi et al., 2019; Torri & Corrêa, 2012).…”

“…In Brazil, Canada, Ireland, South Africa, Turkey, and the United States, prolonged alkalinization is one of the commonest sanitation methods of sewage sludge (Healy et al., 2016; LeBlanc et al., 2008). The majority of studies on soil application of limed sewage sludge addresses soil fertility (Barbosa et al., 2017; Corrêa et al., 2012) and changes in metal concentrations in soils (Dalpisol et al., 2017; Torri & Lavado, 2002).…”

Little attention has been paid to the effects of soil mineralogy on remediation efficiency of sewage sludge. To fill this gap, we applied limed sewage sludge to Pb‐contaminated soil samples of an Oxisol rich in hematite (309 g kg−1) and gibbsite (322 g kg−1) and to an Inceptisol rich in kaolinite (683 g kg−1). Soil samples were collected from B horizon, being both of them acid, clayey, and poor in organic matter. Soil samples were incubated for 40 days and evaluated for Pb after fractioning. Limed sewage sludge neutralized the soluble and exchangeable‐Pb forms in the kaolinitic and oxidic soils primarily as a result of pH increase. It was measured increased concentrations of unavailable forms of Pb such as precipitated‐Pb, Fe and Mn oxide‐Pb, gibbsite and kaolinite‐Pb, and residual‐Pb in the kaolinitic Inceptisol. Likewise, it measured increased concentrations of precipitated‐Pb, organic matter‐Pb, Fe and Mn oxide‐Pb, and residual‐Pb in the Oxisol. Results have demonstrated that limed sewage sludge decreases concentrations of Pb fractions more susceptible to leaching or more bioavailable, while increasing Pb fractions that pose lower risks to the environment. Such results indicate that limed sewage sludge can be used for the remediation of Pb‐contaminated soils regardless of soil mineralogy.

“…A suitable and environmentally correct alternative is the application of sanitary sewage sludge in agricultural and forestry areas, as a soil conditioner and / or organic fertilizer, since it presents in its constitution macro and micronutrients, in addition high organic matter content (Dalpisol et al, 2017;Kummer et al, 2016). However, sewage sludge contains contaminants such as heavy metals, pathogenic organisms and persistent organic compounds.…”

This study aimed to evaluate the total contents of As, Cu and Zn in the profile of a Haplic Cambisol cultivated with crambe and corn and fertilized with sanitary sewage sludge and to compare them with those obtained in other forms of fertilization, as well as the content of metals in the grain of these crops. Two experiments were carried out in the field, one with maize cultivation and another with crambe, both were delineated as randomized blocks with four treatments and six replicates, which were: without fertilization, fertilization with sewage sludge dewatered and dried in the sun, with dry sewage sludge and with mineral fertilizers. At the end of the experiments soil samples were collected at 15, 50, 100, 150 and 200 cm depth for analysis of the total contents of As, Cu and Zn, as well as the grain of the crops. No differences were observed among the treatments. The total contents of As, Cu and Zn in the soil in both experiments and in the corn grains are below the limits of prevention and the maximum limit in grains established by the Brazilian resolutions. In relation to depth, the metal contents in the samples collected from the soil submitted to the fertilization treatments were similar to those quantified in the plots that did not received fertilization, but there was accumulation of Cu and Zn in the upper layers of the soil that received fertilization.
