“…Cabral et al (2014), when applying the doses of 0, 150, 300, 450, 600 and 750 m 3 ha -1 of swine wastewater to an area of elephant grass cultivation, concluded that in the first stage there was an increase but in the second stage there was a reduction of P in the soil, and the same occurred for K + and Ca 2+ . Musazura et al (2019), when using TSE and natural water in banana and taro irrigation, did not find significant differences in N and P uptake by the two crops; however, irrigation with treated effluent increased significantly inorganic N and P, especially at the depth of 0.3 m of the soil. The authors also concluded that there was no difference between the types of irrigation related to phosphorus leaching, but obtained a higher concentration of inorganic N in TSE leachates up to 0.3 m of soil depth.…”

The use of treated sewage effluents (TSE) for irrigation purposes is a viable alternative for wastewater reuse and nutrient supply to the soil, which represent the two main environmental benefits. This work therefore evaluated the effect of the application of TSE on the quantity of nutrients added to the soil and changes in the chemical attributes of a Red-Yellow Latosol in the layer from 0.0 to 0.2 m cultivated with the bell pepper F1 Canary hybrid and surface drip irrigated. The experiment was carried out under field conditions from September 2015 to January 2016 in a randomized block statistical design with four replications, including the following treatments: river water, TSE, river water with base fertilization, TSE with base fertilization, TSE with cover fertilization, and TSE with cover and base fertilization. Irrigation of the bell pepper cultivation with TSE increased the level of potassium but did not affect the levels of phosphorus, organic matter and pH of the soil at the end of the growing cycle. The following amounts of nutrients were added to the soil by irrigation with TSE: 10 kg ha-1 of total nitrogen, 10 kg ha-1 of total potassium and 0.5 kg ha-1 of total phosphate. In general, TSE induced greater productivity of the peppers than those irrigated with river water, even when including mineral fertilization.

“…In view of this, additional studies are necessary to understand salt and nutrient concentrations influence on relationships with plants (Papaioannou et al, 2018). Although agricultural irrigation is an important destination for the TSE, its management must be environmentally sustainable (Musazura et al, 2019).…”

“…This suggests that the organic matter in the wastewater applied to a soil is hardly available to soil microorganisms (Fritz et al., 2022). Reasons for this might be the high salinity of most wastewaters (Musazura et al., 2019), but heavy metal concentrations (Diogo et al., 2010) may also contribute to this phenomenon. Wastewater may also contain high concentrations of recalcitrant purine‐ and pyrimidine‐derived biogenic heterocyclic organic N compounds depending on the feedstock for the gut microbiome (Bosshard et al., 2011; Leinweber et al., 2013).…”

Background Little is known about the effects of gypsum application to remediate saline–sodic soils in the tropics and the role of microbial indicators in soil reclamation. Aims Our study aimed at (1) remediating a highly weathered, irrigated sodic Lixisol under prolonged urban crop production by clean water and gypsum application and (2) to determine the remediation effects on soil microbial indices. Methods A three‐factorial on‐farm experiment with maize (Zea mays L.) was used to study effects on soil microbial biomass of (1) soil degradation at two levels of salinity, (2) irrigation with clean water and wastewater, and (3) the impact of added gypsum during a typical growing season. Results At the high‐degradation site, the 0.5 M K2SO4 extractable carbon (C) content was 40% higher than at the low‐degradation site. In addition, microbial biomass carbon (MBC) and microbial biomass nitrogen (MBN) were 20% lower than at the low‐degradation site, while fungal ergosterol was even 40% lower, leading to a 33% lower ergosterol/MBC ratio. Wastewater irrigation increased MBN but decreased ergosterol content at the low‐degradation site while having no effect at the high‐degradation site. Gypsum amendment led to higher MBN at the low‐degradation site but to lower MBN at the high‐degradation site. Gypsum amendment always increased the ergosterol content whereby this increase was stronger at the low‐degradation site, especially in combination with wastewater irrigation. Conclusions From a microbial perspective, high soil degradation levels should be avoided by treatment of a saline–sodic wastewater prior to its use for irrigation rather than relying on future remediation strategies of affected field sites.
