“…Soil is a dispersed, polyphase, and heterogeneous system and, due to its physical, chemical and biological attributes, it allows the deposition of wastewater acting as a scrubber through the interception of suspended solids and nutrient removal [1]. e presence of residual water in the soil through the irrigation of plants alters its chemical characteristics [2,3], which can lead to possible toxicity problems depending on the concentration of the chemical elements present in the effluent [4]. Accumulation of salts may occur in the soil [5][6][7], as well as the contamination of surface and underground water sources [8].…”

“…By applying the PCA technique to find variables that could be used to monitor areas treated with sewage sludge, Coscione et al [19] observed that the attributes pH, Mn 2+ , SO 4 2− , NO 3 − , NH 4 + , and organic carbon dissolved in soil solution, which are trace elements left by soil residue, were useful to identify these areas with regard to applied fertilization sewage and mineral fertilization. In a study by Chen et al [20], using PCA to verify the influence of irrigation water quality on soil attributes, reported that the ionic components of irrigation water directly influenced soil saline ions and have shown that the ionic effects of irrigation water on soil processes would be more complex than currently understood.…”

The agricultural use of domestic sewage is a viable alternative for recycling nutrients; however, there is concern regarding the impact of its use due to the concentration of chemical elements present in this type of effluent. The use of principal component analysis determines the existence or lack of anomalous samples and the relations between measured variables and their relative contribution among samples that help in monitoring the impact of the use of effluents on soil chemical components. Thus, the objective of this work was to identify nutrient ions present in the soil solution during the first ratoon sugarcane irrigated with treated domestic sewage applied by subsurface drip irrigation. The experiment was conducted under a randomized block design with 5 treatments and 5 replicates. The treatments were distributed according to the type of water applied in the irrigation system (water surface reservoir and treated domestic sewage), the installation depth of the drip tapes (0.2 or 0.4 m depth), and the treatment without irrigation. By means of soil solution, it was possible to identify an increase in the concentration of salts in the treatments irrigated with treated domestic sewage, which however did not affect the soil quality in the short term. The principal component analysis selected the variables Ca2+, Mg2+, NO3−, K+, and EC as soil solution indicators to monitor areas irrigated with treated domestic sewage.

“…Numerous studies have been carried out to verify updates to crop yields and various attributes of soil irrigated with TSE, such as the electrical conductivity (EC), sodium level (Na), pH, organic matter and others (Duarte et al, 2008;Sandri et al, 2009;Oliveira et al, 2016;Urbano et al, 2015;Silva et al, 2016;Malafaia et al, 2016;Sandri and Rosa, 2017;Soothar et al, 2018). Thus, studies indicate that one must be careful when using TSE in plant cultivation, especially with plants sensitive to saline soils.…”

“…Despite the great potential of TSE for agricultural use, if used improperly it can be harmful to the irrigation system, soil, plant, water resources and users. For example, Silva et al (2016) found that when using treated sewage in irrigation there was a greater accumulation of micronutrients, potassium and sodium in the soil in relation to water of the public supply system, increasing the risks of sodification. Tunc and Sahin (2015) reported that soil chemical, physical and hydraulic properties can be significantly affected by irrigation with wastewater.…”

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.

Irrigation with recycled domestic wastewater has been known to obtain positive effects on improving soil fertility, but it may also become a risk factor in case of causing an increase in soil salinity and/or heavy metal concentration of soil. No-tillage can retain soil moisture, helping to reduce irrigation water necessity, and thus lower amounts of heavy metals and salts are added to soil under wastewater irrigation conditions. The objective of this study was to analyze the effects of wastewater irrigation at different levels of on silage maize cultivation under conventional tillage and no-tillage conditions by comparing to full irrigation with fresh water. The two-year experiment was planned according to the split-plots design in the random blocks with three replications. The results indicated that full irrigation with wastewater increased soil salinity, organic matter content, total nitrogen, plant available phosphous, exchangeable cations, exchangeable sodium percentage and soil essential and non-essential heavy metal contents, but decreased soil pH and lime content. Increasing rates in organic matter content, total nitrogen, plant available phosphorus and exchangeable potassium were higher, but in electrical conductivity, and heavy metal accumulation were lower in soil under no-tillage as compared to conventional tillage. Contamination and enrichment factors and geographic accumulation index showed that non-essential heavy metal contamination due to cadmium and nickel, increased in full irrigation with wastewater. Irrigation with wastewater also increased heavy metal accumulation in silage maize. No-tillage can be a recommendable water management practice considering that the risks of soil salinity and heavy metal accumulation can be reduced and that soil fertility can be increased. Also, in reducing the risk of accumulation of cadmium and nickel in soil, 33% deficit irrigation with wastewater can make no-tillage more available.
