“…Soil irrigation with wastewater increases the soil conductivity due to its nutrient content and organic matter and soil salinity [7]. High nitrogen contents of wastewater tend to increase the organic and inorganic nitrogen pool [8]. Similar results have also been stated by Elfanssi et al [9] who reported increase in conductivity, organic matter and N content in soil irrigated with raw wastewater.…”

Irrigation of agriculture field by untreated wastewater is a common practice in the water scarce regions in India. Increasing water crisis has forced the farmers to use untreated or partially treated wastewater in their agricultural fields. In this study, agricultural soil irrigated with textile effluent was examined at five different sites on the basis of proximity to the source and analysed for physicochemical and microbiological properties. Further, the co-relation of physicochemical properties with soil enzyme was also studied. The results revealed that soil respiration and microbial biomass carbon reduced by 53.8% and 65.9%, respectively in the contaminated site as compared to control site, emphasizing the deleterious impact of effluent on the study site. Additionally, the bacterial population and dehydrogenase enzyme reduced by 41.6%, and 71%, respectively in the effluent affected soil as compared to the control site. Soil organic carbon showed a strong positive correlation (p ≤ 0. 01) with soil enzyme activity. Other physicochemical and microbiological properties of the affected soil indicated negative impact on both soil quality and microbiota.

“…Due to increasing interest in the use of sewage for irrigation and in light of the possible effects of sewage on agricultural soils and crop production, the influence of effluent irrigation on the physical, chemical, and biological properties of soil have been well documented [ 6 , 7 , 8 ]. Previous studies have shown that sewage irrigation is frequently accompanied by increases in macro- and micro-nutrients and heavy metals in the soil [ 9 , 10 , 11 , 12 ] in addition to changes in soil microbial functional diversity and enzymatic activity [ 13 , 14 , 15 ]. Sewage irrigation can also increase the risk of crop and groundwater pollution [ 16 , 17 ] and reduce soil quality [ 18 ] and the infiltration rate [ 8 , 19 ].…”

Sewage irrigation has a strong influence on the physical, chemical, and biological properties of soil. However, the effects of sewage irrigation on the pore characteristics of soil are not well understood. This study compares the effects of sewage irrigation and groundwater irrigation on computed tomography (CT)-measured pore parameters and examines the relationships between CT-measured pore parameters and soil physicochemical and microbial properties. Intact soil cores were collected from S1 irrigated with sewage for 25 years, S2 irrigated with sewage for 52 years, and CK irrigated with groundwater. Various soil pore characteristics were determined, including the total pore number, macropore number (>1 mm diam.), coarse mesopore number (0.264–1 mm diam.), total porosity, macroporosity, coarse mesoporosity, and circularity. The results indicated that sewage irrigation significantly affected soil pore number and porosity. Compared with S1 and S2, CK exhibited a higher average total pore number (91), macropore number (40), coarse mesopore number (51), total porosity (2.08%), macroporosity (1.90%), and coarse mesoporosity (0.18%) throughout the 50–350 mm layer. At depths of 200–350 mm, S2 exhibited the lowest average total pore number (33), macropore number (13), coarse mesopore number (21), total porosity (0.42%), macroporosity (0.35%), and coarse mesoporosity (0.07%) among the three sites. In addition, the average pore numbers and porosity at depths of 200–350 mm decreased with increasing sewage irrigation time. There were significant positive correlations between pore features (including pore numbers and porosity) and soil properties (phosphorus content and fungi numbers). Our results suggest that decreased macropore numbers and macroporosity in the sewage-irrigated farmland may strongly intensify the accumulation of metals and nutrients in the upper layer. The findings of this study are useful for understanding the negative effects of sewage irrigation on soil pore structure and are critical for developing sustainable strategies in agriculture.

The concern of this study is determine the quality of soil when irrigation used treated water and wastewater in comparison with soil irrigated with tap water on some chemical and physical soil properties. The experiment components were three trials carried out under greenhouse conditions, 10 pots for each trial. The first trial irrigated with tap water, the second trial irrigated by treated water and the third trial irrigated with wastewater. The experiment conducted to study the impact of water types on some soil physical and chemical properties. The experiment included important analysis for water and soil before and after irrigation. The results showed that the values for electrical conductivity (EC) were 0.850, 308 and 324 μs/cm for the treated soil with tap water, treated water and wastewater, respectively. The variation of pH values seems to be approximately constant between the different of water used. The percent of organic matter (OM) in soils receiving treated water and wastewater 4.7% and 5.2% respectively were higher than values in soil treated with tap water 3%. The same trend was in organic carbon (OC) in soils receiving treated water and wastewater 58.5% and 89% respectively, while soil treated with tap water showed the lowest value 27.7%. Soil particle density (SPD) increased significantly in both water treatments were the values was 2 g/cm 3 in tap water but increased value 2.8 g/cm 3 and 3.3 g/cm 3 in treated water and wastewater used respectively. The Bulk Density (BD) values range 1.1 g/cm 3 in soil irrigated with tap water 1.5 g/cm 3 in soil irrigated with treated water and 1.85 g/cm 3 in soil irrigated with treated water. The results of soil analysis before and after planting showed that most of the values increased for the physical and chemical soil properties.
