“…These results coincide with Eden et al [66], who reported a positive effect of organic waste on soil water in sandy soil, and with Ferreiro-Domínguez et al [51], who found positive effects of SS on soil pH. Soil nutrient element concentrations are important factors affecting soil health and plant growth [67]. Generally, sandy soil in semiarid areas is low in soil organic carbon, nitrogen, and phosphorus contents.…”

The application of domestic sewage sludge (SS) may affect plant growth and soil quality through altering nutrient availability. However, the effect of SS application on the plant–soil system in sandy soils is poorly understood. In this study, we established SS application treatment plots (SL, 25 t ha−1) and control treatment plots without sewage sludge application (CK, 0 t ha−1). SS was applied to the soil surface of a Mongolian pine (Pinus sylvestris var. mongolica) plantation in Horqin Sandy Land, Inner Mongolia, China, to assess its potential effects on plants and soil. We analyzed tree growth performances (tree height, basal diameter, and diameter at breast height), understory traits (species diversity, coverage, and aboveground biomass), soil physical and chemical parameters (nutrient content, dissolved organic carbon, soil water content, bulk density, pH), and proxies of ecosystem services (soil organic carbon and total nitrogen stocks). The results showed that SS addition not only significantly increased soil nutrient contents, but also markedly enhanced aboveground productivity and plant coverage. Specifically, SS addition decreased soil bulk density and increased concentrations of soil organic carbon, total nitrogen, and total phosphorus and mineral nitrogen, and it also increased soil carbon and nitrogen stocks. Furthermore, the addition of SS significantly increased soil dissolved organic carbon contents and enhanced the fluorescence intensities of dissolved organic carbon components (humic acid-like and UV fulvic acid-like) in the topsoil (0–5 cm). This study provides evidence that SS is an acceptable, and possibly preferred organic fertilizer for improving the soil quality and tree–grass growth of Mongolian pine plantations.

“…The remaining solid residue, biochar, has good potential to improve soil quality via increasing contents of soil nutrients (i.e., N, P, and K), soil microbial biomass, and soil pH [ 10 ]. The integration of sewage sludge biochar into agricultural soil can enhance soil fertility by promoting nutrient supplementation, improving soil aeration and cation exchange capacity [ 11 ]. Besides pyrolysis, co-pyrolysis of sewage sludge and biomass wastes such as crop straw and wood chips was also employed as a promising method to produce biochar with better characteristics (e.g., high stability, moderate pH, and high available phosphorus content) and low metal toxicity [ 12 ].…”

Large amounts of sewage sludge (SS) and wetland plant wastes are generated in the wastewater treatment system worldwide. The conversion of these solid wastes into biochar through co-pyrolysis could be a promising resource utilization scheme. In this study, biochar was prepared by co-pyrolysis of SS and reed (Phragmites australis, RD) using a modified muffle furnace device under different temperatures (300, 500, and 700 °C) and with different mixing ratios (25, 50, and 75 wt.% RD). The physicochemical properties of biochar and the transformation behaviors of phosphorus (P) and heavy metals during the co-pyrolysis process were studied. Compared with single SS pyrolysis, the biochar derived from SS-RD co-pyrolysis had lower yield and ash content, higher pH, C content, and aromatic structure. The addition of RD could reduce the total P content of biochar and promote the transformation from non-apatite inorganic phosphorus (NAIP) to apatite phosphorus (AP). In addition, co-pyrolysis also reduced the content and toxicity of heavy metals in biochar. Therefore, co-pyrolysis could be a promising strategy to achieve the simultaneous treatment of SS and RD, as well as the production of value-added biochar.

“…Sewage sludge is used as a fertilizer. These sources contain a large amount of nutrients, which can enhance conditions for plants' growth, but also can increase the CO 2 emission from soils (e.g., Carmo et al, 2014;Dhanker et al, 2021;Fernández-Luqueño et al, 2009;González-Ubierna et al, 2015;Lloret et al, 2016;Paramasivam et al, 2008;Paudel et al, 2018;Sheppard et al, 2005;Yerli et al, 2022). In addition, it has been found that these sources also include variety of micropollutants including the human and veterinary pharmaceuticals that can contaminate soils and plants (e.g., Carter et al, 2019;Grabic et al, 2022;Ivanová et al, 2018;Klement et al, 2020;Kodešová et al, 2019a, b;Picó et al, 2020) and can also stimulate the CO 2 emission from soils (e.g., Fér et al 2020).…”

“…Despite that these soil amendments can have a significant impact on the CO 2 emission from soils, their actual effect on measured values has not been fully revealed. It has been found that the CO 2 emission increases with the increasing dose of a sewage sludge (Dhanker et al, 2021;Fernández-Luqueño et al, 2009), or that the impact of a sludge from different resources or resulted from different stabilization treatments on the CO 2 emission can differ (Carmo et al, 2014;Fernández-Luqueño et al, 2009;González-Ubierna et al, 2015). In addition, Fernández-Luqueño et al (2009) showed that the emission of CO 2 from sludge amended soils can be also affected by plants and this effect depends on a phenological stage of the plants.…”

The goal of this study was to evaluate the effect of products from a municipal wastewater treatment plant on the H2O and CO2 effluxes from two soils. The net H2O and CO2 effluxes were measured at the surface of nine beds with two different soils (Cambisol and Arenosol) and two crops (maize or vegetables). Soils in some beds were amended with stabilized sewage sludge (bed with Cambisol and maize) or composted sewage sludge (two beds with Cambisol and both crops) or were irrigated with treated wastewater (two beds with Cambisol and both crops, and one bed with Arenosol and vegetable). Remaining beds were irrigated with tap water (two beds with Cambisol and both crops, and one bed with Arenosol and vegetable). While stabilized and composted sewage sludge positively affected the CO2 emission, the effect of treated wastewater was not confirmed. Different treatments had negligible effect on the water efflux, which was mainly affected by the plant canopy that influence the temperature of the soil surface. Statistical analyses showed that trends of the CO2 efflux with respect to various scenarios measured on different days changed during the season. No significant correlations were found between the average H2O and CO2 effluxes and measured soil properties.
