“…The arylsulfatase activity showed a trend of increasing and then decreasing and was the highest in the early stage of sewage sludge composting ( Figure 4 ). This trend is consistent with studies by Meena et al [ 44 ] and Ma et al [ 45 ]. The maximum arylsulfatase activity was 1.42, 1.45, 1.35, and 1.04 μg·g −1 ·h −1 in the control batch and the treatments comprising the addition of 4%, 8%, and 12% KNO 3 .…”

“…Arylsulfatase, an important enzyme involved in the sulfur metabolism during composting, releases SO 4 2− by hydrolyzing the thioester bond (SO) in organic sulfur (ROSO 3 − + H 2 O → ROH + SO 4 2− + H + ), and its activity is related to the concentrations of organic sulfur and SO 4 2− [ 43 , 44 ]. The arylsulfatase activity showed a trend of increasing and then decreasing and was the highest in the early stage of sewage sludge composting ( Figure 4 ).…”

Odor released from the sewage sludge composting process often has a negative impact on the sewage sludge treatment facility and becomes a hindrance to promoting compost technology. This study investigated the effect of adding KNO3 on the emissions of volatile sulfur compounds, such as hydrogen sulfide (H2S), dimethyl sulfide (DMS), and carbon disulfide (CS2), during sewage sludge composting and on the physicochemical properties of compost products, such as arylsulfatase activity, available sulfur, total sulfur, moisture content, and germination index. The results showed that the addition of KNO3 could inhibit the emissions of volatile sulfur compounds during composting. KNO3 can also increase the heating rate and peak temperature of the compost pile and reduce the available sulfur loss. The addition of 4% and 8% KNO3 had the best effect on H2S emissions, and it reduced the emissions of H2S during composting by 19.5% and 20.0%, respectively. The addition of 4% KNO3 had the best effect on DMS and CS2 emissions, and it reduced the emissions of DMS and CS2 by 75.8% and 63.0%, respectively. Furthermore, adding 4% KNO3 had the best effect from the perspective of improving the germination index of the compost.

“…At the end of 3 years of experiment, SOC was in the order: MSWC (4.3 g kg −1 ) > GEC (4.0 g kg −1 ) > RSC (3.9 g kg −1 ) > RDF (3.3) > Control (1.5 g kg −1 ). The highest SOC was registered in all organically amended plots as compared to 100% RDF and control treatments, it can be explained that different quantities of organic matter were incorporated into the soil, enhances the SOC concentration and it also depends on their chemical composition and decomposition rate (Meena et al, 2021; Yazdanpanah et al, 2016). Higher C:N ratio (35.1 ± 0.4) in MSWC treatment was resulted in lower rates of carbon mineralization and CO 2 production and ultimately produced more stabilized SOC.…”

Soil salinity is a severe threat in arid and semiarid agro‐ecosystem of India, and it is directly influenced by soil physical properties. Therefore, understanding the dynamic nature of salinity is the key to implementing suitable management options for re‐builing the fertility of saline soils. In this context, we conducted field experiments in saline soil, comprising five treatments (1‐5 following) and a control (C). These are: C) no amendments and chemical fertilizer; T1) recommended dose nitrogen, phosphorus, and potassium (N‐P‐K) fertilizers @60:30:30 kg ha−1; T2) 100% recommended dose of chemical fertilizers (RDF).; T3) rice straw compost (RSC) @14 Mg ha−1; T4) gypsum enriched compost (GEC) @14 Mg ha−1; and T5) municipal solid waste compost @16 Mg ha−1 (MSWC) applied for three consecutive years (2012 to 2015). Our results revealed that compost and chemical fertilizer had significant effect on soil organic carbon, soil aggregate stability indices, soil water retention, transmission characteristics, and pore size distribution. This improvement in soil physical properties imparted into better soil physical environment and significant reduction in soil salinity (75%) was apparent with application of MSWC. Multivariate analysis indicated that mean weight diameter (MWD) and retension pores (RP) were the two main soil physical properties that help to reduce soil salinity. Our results revealed that, MWD increased by 49.1% in MSWC and 37.7% in GEC over control (C) (0.53 mm). Improvement in soil environment under composted soil produced significantly higher grain yield of mustard (2.22 Mg ha−1) and pearl millet (2.29 Mg ha−1) with MSWC as compared to control (C). Organic amendments significantly improved the soil physical environment.

“…In sandy soil condition, addition of FYM and organic residues reduces the toxic metal leaching and improves the soil health (Meena et al, 2018 ). Addition of MSW compost in soil improves the plant nutrient concentration and labile part of the sulphur (Meena et al, 2021 ). Microbial population and diversity enhance the secretion of low molecular organic acids in soil and improve the plant nutrient dynamics during crop growth stages.…”

The availability of freshwater is limited for agriculture systems across the globe. A fast-growing population demands need to enhance the food grain production from a limited natural resources. Therefore, researchers and policymakers have been emphasized on the production potential of agricultural crops in a sustainable manner. On the challenging side, freshwater bodies are shrinking with the pace of time further limiting crop production. Poor-quality water may be a good alternative for fresh water in water scarce areas. It should not contain toxic pollutants beyond certain critical levels. Unfortunately, such critical limits for different pollutants as well as permissible quality parameters for different wastewater types are lacking or poorly addressed. Marginal quality water and industrial effluent used in crop production should be treated prior to application in crop field. Hence, safe reuse of wastewater for cultivation of food material is necessary to fulfil the demands of growing population across the globe in the changing scenario of climate.
