“…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).…”

“…Thus, sludge application can be considered beneficial because C is a key factor in soil quality (Lal, 2015). Tamanini et al (2008) similarly reported a linear increase of organic C in degraded soil after the application of alkaline sewage sludge. Marin et al (2010) using alkaline sewage sludge, and Neto et al (2016) using alkaline residues from the pharmaceutical industry did not detect an effect on soil organic C. However, the increase in organic C content ( Figure 4B) was not related to the amount of C added via the sludge (Table 2).…”

Alkalinized sewage sludge application improves fertility of acid soils

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.

“…In practice, this increase of ionic strength in the soil solution may be caused by the excessive discharge of residues and effluents, especially if the pollutant contains competitive cations in its composition . Tamanini et al (2008) observed a linear increase between total Ca and sewage sludge application rate due to rapid release of calcium hydroxide. Specific adsorption mechanisms are usually accompanied by H + ion release to the soil solution, as a result of their displacement so that the linking of high energy occurs between the surface and the metallic ions.…”

“…The pH is the primary factor that controls heavy metal adsorption and their availability (Harter, 1983;Casagrande et al, 2008). However, residues and effluents applied to the soil may contain a series of specific chemicals in solution (Tamanini et al, 2008) and the electrolytic concentration is frequently higher than that found in the soil solution (Bowman et al, 1981). The dependence of adsorption with regard to ionic strength is used to distinguish the outer-and inner-sphere adsorption mechanisms, which informs the stability and intensity of the retention process (Petruzzelli et al, 1985;Kosmulski, 1997;Criscenti and Sverjensky, 1999).…”

“…Moreover, these residues can also be used for reclamation of degraded soils (Tamanini et al, 2008). Due to the general predominance of organic matter, sewage sludge or composted domiciliary wastes increase the soil organic matter, and consequently its water holding capacity and nutrients, and stimulate the soil microbial activity (Oliveira et al, 2002;Betiol and Fernandes, 2004).…”

Soil Health refers to the ecological equilibrium and the functionality of a soil and its capacity to maintain a well balanced ecosystem with high biodiversity above and below surface, and productivity. To understand and use soil health as a tool for sustainability, physical, chemical, and biological properties must be employed to verify which respond to the soil use and management within a desired timescale. Attributes with a rapid response to natural or anthropogenic actions are considered good indicators of soil health. Among the physical indicators, soil texture, aggregation, moisture, porosity, and bulk density have been used, while among chemical indicators total C and N, mineral nutrients, organic matter, cation exchange capacity, among others are well established. However, most of them generally have a slow response, when compared to the biological ones, such as microbial biomass C and N, biodiversity, soil enzymes, soil respiration, etc., in addition to macro and mesofauna. Thus, a systemic approach based on different kinds of indicators (physical, chemical and biological) in assessing soil health would be safer than using only one kind of attribute. Many human activities have caused desertification, loss of biodiversity, disruption of aggregates, loss of organic matter and nutrients, among others. Today, it is imperious to maintain soil health and productivity with increasing emphasis on reforestation and recuperation of degraded areas through the use of organic amendments, reintroduction of plants, soil fauna and microorganisms. This review focused on an integrative view on indicators of soil health to be used as tools for prediction of sustainability in production systems.
