“…The experiments showed a great potential for both DSS and ISS wastes in the increase of fresh and dry mass of the aerial part, besides a strong correlation between the DSS and ISS doses (Figures 1D and 1E). These results corroborate and show that the use of these organic residues as alternative sources can replace commercial mineral fertilizers because they provide all essential nutrients for crop growth and productivity (BOECHAT et al, 2015).…”

“…These results are supported by the chemical characterisation of sewage sludge that altered the initial chemical characteristics of the soil. Moreover, as a result of the elevation of soil pH, there is an increase in the capacity to provide nutrients to the plants ( BOECHAT et al, 2015), and assistance in structuring the soil (BONINI et al, 2015) (Table 2). *-Significant effect at the 1% level of probability by F-test; **-Significant effect at the 5% level of probability by F-test; ns -not significant effect by F-test.…”

“…Outstanding among the wastes studied are steel mill slag and urban sewage sludges. These wastes have proved to be an excellent substitute for limestone, since besides correcting the pH they are a major source of nutrients for the plants [67][68][69][70].…”

In recent decades, projections involving population growth, changes in consumption paterns, modiications of the wastes produced, and a signiicant increase in resource extraction have caused concern in the scientiic world, in treatment companies, and in environmental and governmental agencies throughout the world, regarding the destination of the large volume of solid wastes generated, the relatively high contents of potentially toxic, carcinogenic and mutagenic substances and pathogenic microorganisms. Waste management has become very important to ensure elementary resources such as water, phosphorus, and food in the future. The recycling policy thus requires that wastes be classiied in terms of their appropriateness for new uses and also based on their origins and hazardousness of handling. These classiications are essential in order to allow a minimum of rationality in their new destinations. Currently, several studies have been performed to use solid wastes from human activities as soil conditioners and/or fertilizers for increasing crop productivity. Therefore, studies that monitor organic waste efects on agricultural soils deserve the atention of the international scientiic community, as it enables increases in the productivity of agricultural crops, iber, and biomass energy combined to reduce risks to human, plant, and animal health and environment.

“…Compared with urban sewage (reclaimed water), RDRW has the characteristics of small differences in water quality, dispersed water, high N and P content and good biodegradability, and it generally does not contain toxic substances such as heavy metals. It can be used as a fertilizer resource, and it is easier to guarantee the safety of irrigation reuse (Boechat et al, 2014;Li et al, 2015;Zalac ain et al, 2019). As a food crop with high water consumption, rice is an important contributor to the regional ecological environment, which can maximize the consumption and utilization of domestic sewage (Xiao & Li, 2021).…”

Rural domestic reclaimed water (RDRW) for agricultural irrigation is an effective way to alleviate the contradiction between the supply and demand of water. In this research, four kinds of irrigation water sources (primary and secondary treated water [R1 and R2], purified water [R3] and river water [CK]) and three kinds of water level regulations (low, medium and high water level control [W1, W2 and W3]) were set to study the impact of RDRW irrigation and its reuse on the properties of paddy soil, water and nitrogen utilization and yield of rice through a combination of field experiments and laboratory and numerical analysis methods. The results showed that compared with river water (CK) irrigation, pH (0–40 cm), electrical conductivity (EC) and organic matter (OM) content (60–80 cm) increased, and ammonium‐nitrogen (NH4+‐N) (0–20 cm) and nitrate‐nitrogen (NO3−‐N) (40–60 cm) content accumulated under RDRW irrigation. Under high water level regulation (W3), NH4+‐N and NO3−‐N content increased, showing the opposite changing trend compared with W1 and W2 regulations. With RDRW irrigation, water and nitrogen use efficiency and rice yield were significantly increased. Under RDRW irrigation, irrigation water use efficiency (IWUE), nitrogen use efficiency (NUE) and rice yield were increased by 48%–70%, 10%–22% and 5%–13%, respectively, compared with CK irrigation. In addition, path analysis established by structural equation modelling (SEM) showed that the irrigation water amount (IWA) had a significant positive impact on NUE and NH4+‐N but had a significant negative impact on IWUE and EC. NUE, IWUE, NO3−‐N and EC had a significant positive impact on yield. The path of IWA= > IWUE= > yield showed a complete mediation effect, the path of IWA= > EC= > yield and NUE= > EC= > yield both showed a partial mediation effect, and the effect size was 27.9% and 25.0%, respectively.
