“…As most of soil inorganic P in the SS treatments was in the moderately labile fraction, with higher P i /P o ratio (Figures 2D-F), it is expected that there will be a continuous long-term release of available inorganic P into the soil solution and taken up by plants, thus reducing the risk of loss by transforming to non-labile forms. This result was corroborated by Florentino et al (2019) who reported high soil resin-P concentration even after more than 17 years of sewage sludge application in four fields of Eucalyptus plantations, as compared to the control and mineral fertilization treatments. These findings reinforce the importance of soil inorganic moderately labile P fraction for the long-term effect of SS application on legacy P.…”

“…The management and disposal of SS are complex and expensive, and SS reuse in several fields of application has tremendously increased worldwide (Cieślik et al, 2015). SS application as soil fertilizer/amendment in agriculture is the most promising practice (Abreu-Junior et al, 2005Franco et al, 2010;Florentino et al, 2019;Nascimento et al, 2020). Depending on its origin and quality, SS may contain a huge amount of organic matter and essential elements for plants (Bettiol and Ghini, 2011), thus replacing or integrating mineral fertilizers of non-renewable origin widely used for crop cultivation (Alleoni et al, 2012;Ferraz et al, 2016;Abreu-Junior et al, 2017).…”

Phosphate fertilizers used in planted forests mainly come from scarce and nonrenewable sources, and there is a need for new sources of phosphorus (P). An alternative is the use of sewage sludge (SS), rich in organic matter, nitrogen, and P. The objectives were to evaluate the soil P availability and its effect on wood production in 22month-old Eucalyptus urograndis plantation treated with SS. A field experiment was set up in a randomized complete block design, four replicates, with the following treatments: control without fertilization; mineral fertilization (MF); 14.5 Mg ha −1 of SS + 22 kg ha −1 of P (S1P1); 29 Mg ha −1 of SS (S2); 29 Mg ha −1 of SS + 17.5 kg ha −1 of P (S2P2); and 43.5 Mg ha −1 of SS (S3), dry base. Of the total P in SS, 65% was in organic form and 42% was in labile + moderately labile forms. S2P2 and S3 positively altered the pattern of soil P distribution, with more P in the labile and moderately labile fractions than in the non-labile fraction, along 0-20 cm depths, than MF and control. There were higher microbial and available P as a function of SS dose. Wood volume and biomass were highly related to soil P availability as a function of SS dose. Within the SS treatments, S2P2 resulted in higher gains of volume and biomass of wood. The SS application at the recommend rate, supplemented with 66% of recommended P fertilizer dose in Eucalyptus plantations, can reduce the use of P fertilizer by 33% and N fertilizer by 100% and maintain comparable soil P availability and wood production.

“…In the present study, the co-compost derived from sewage sludge and biochar as one of the bulking agent. So the fluctuations can be understood as per the previous author's report Florentino et al [14], that direct application of sewage sludge on soil resulted in reduced pH due to proton release during decomposition. Conversely, Figueiredo [15] reported that pyrolysis of sewage sludge (biochar) can increase pH of the soil.…”

Depriving soil fertility serves as one major cause for reduced crop growth rate and production, which in turn affects the food productivity. Various soil conservation measures to sequester the soil nutrients are adopted in developing countries locally and conventionally. In another scenario, present day sewage treatment plants (STP) across the nation are struggling to treat the receiving water quantity effectively. The fluctuations in receiving quantity of waste water resulted in untreated excess sludge dumping in nearby places. In order to synergize the excess sludge dumping in a feasible way by land management practices, the present study aims to compare two methods of sludge incorporating into soil, namely co-composting and direct ponding. Samples were collected from two different plots receiving sludge for different duration (fresh and old) at different depths (12 cm, 24 cm and 36 cm) and analyzed for various physicochemical parameters. The study also highlights the co-composting of sewage sludge with other community wastes to contribute a better analogy on nutrient redistribution. The obtained results of 17.34 mg/l total organic carbon and 1.392 mg/l total nitrogen at 36cm depth in old sludge ponding sites reveals the improved capability of sludge leachate against the soil nutrient attenuation. It finds application in agricultural practice to promote crop growth under controlled conditions of sewage sludge amendment as ponding and co-composting.

“…In addition to providing essential nutrients, organomineral fertilizers potentially increase the soil chemical quality due to the increase of the soil's negative charges, extending the cation exchange capacity (CEC) and reducing the concentration of exchangeable aluminum (Al 3+ ) [42][43][44]. The soil organic matter correlated with the regular applications of N and P, and with high soil CEC when sewage sludge was used as the source for organomineral fertilizer [45]. The monitoring of the environmental conditions and the orientation of farmers of this raw material (sewage sludge) on public policies is also essential to avoid heavy metals and biological contaminants during the reuse and management of this environmental liability [45].…”

Sugarcane is one of the major alternatives for the biofuel sector and its large production has considerable environmental impacts. Organomineral fertilizers formulated with environmental liabilities such as filter cake and sewage sludge positively affect parameters of plant growth and development. The objective of this study was to evaluate the chemical and technological characteristics of sugarcane fertilized with pelletized organomineral fertilizers based on filter cake and sewage sludge. Eight field treatments were studied, being three levels of organomineral (50, 100, 150%) of two organic matter sources (filter cake, sewage sludge), plus a control with 100% of the recommended fertilization via mineral fertilizer and no fertilization control (0%). Sugarcane was evaluated during two consecutive harvest, and the amount of stalks per hectare (ton ha−1), the sugarcane productivity (ton ha−1), the quantity of sugar per hectare (TSH, ton ha−1), and the chemical and technological analysis of the sugarcane juice: pol (%), brix (%), purity (%) and fiber (%) were evaluated. None of the organomineral sources or doses differed from the exclusive mineral fertilization. The analysis of both harvests indicated that the first cut was the most productive since the responses of the first harvest were superior or similar to the second harvest. The recommended organomineral dose to obtaining maximum quantitative and qualitative sugarcane results was between 102 and 109% of the regular recommendation for mineral fertilization, regardless of the organic source in the first sugarcane harvest. In the second sugarcane harvest, sewage sludge source increase by 4.68 and 4.19% the total amount of sugar per hectare and the quantity of sugarcane compared to the sugarcane filter cake source. Sewage sludge and sugarcane filter cake as sources for organominerals are viable alternatives and advantageous in economic and environmental terms for the cultivation of sugarcane.
