“…Increase in TW concentration favored soil salinization ( Figure 3L), which may explain the quadratic behavior observed in clay soil. The use of untreated or improperly treated wastewater in agricultural irrigation may impair plant growth and development and the absorption of nutrients due to possible soil salinization and contamination of plants and soil with pathogens, heavy metals or other toxic elements (Bedbabis et al, 2015;Chen et al, 2016;Demir;Obayomi et al, 2019;Sou-Dakouré et al, 2013). In sandy loam soil, increased concentration of TW in the irrigation water caused a linear increase in the the accumulation of all nutrients, except for P, Fe, and Cu.…”

Wastewater can be considered an excellent nutritional and water source for cultivated plants. However, the presence of high concentrations of salts and toxic compounds can negatively affect crops. The effect of irrigation with different concentrations of treated wastewater on the accumulation of nutrients and gas exchange aspects of millet (Pennisetum glaucum (L.) R. Br.) grown in clay soil and sandy loam soil was analyzed. This study was conducted in a greenhouse (16°40’57,50” S; 43°50’26,07” O; 650 m) in a 5 x 2 factorial design, consisting of five levels of concentration of treated wastewater (0, 25, 50, 75, and 100%), combined with two types of soil (clay and sandy loam). The experiment was designed in randomized blocks with four replicates. The increase in treated wastewater concentration in irrigation water applied to clay soil and sandy loam soil favored the increase of net photosynthesis, transpiration rate, stomatal conductance, leaf chlorophyll content and accumulation of macro- and micronutrients in millet plants. Millet plants grown in clay soil showed an average increase of 23% in gas exchange capacity and 71% in accumulation of macro- and micronutrients, when compared with treatments in sandy loam soil. Therefore, treated wastewater contributes to the increase in gas exchange capacity and greater accumulation of nutrients in millet plants, which represents an alternative for reduced demand for fresh water and use of chemical fertilizers.

“…The authors verified that in well drainage, the nitrates presence in leachates can increase according to water salinity. Chen et al (2015) evaluated the risk of long-term irrigation by treated papermaking wastewater (TPW) in reed wetland from Yancheng Biosphere Reserve of China on the soil and microbial viability and therefore the suitability of TPW reuse for irrigation. The authors found that although long-term TPW irrigation may increase the soil fertility and microbial activity, heavy metals such Cd and Pb and salinity can be accumulated in the soil.…”

“…Treated wastewater reuse for irrigation, landscape and surface or groundwater replenishment purposes is being widely implemented (Abourached et al, 2016;Fiorentino et al, 2016;Chen et al, 2016). Although, the reuse practice is accompanied by a number of benefits relating to the enhancement of water balances and soil nutrition by the nutrients existing in the treated effluents, a number of unanswered questions are still related to this practice (Fatta-Kassinos et al, 2011).…”

The countless generation of waste (solid or liquid) by agro-industrial activities, has stimulated the development of researches aimed not only at the processing of these materials but also the possibility to take advantage of them in the agricultural environment. Therefore, this study aimed to evaluate the production of maize plants (Zea mays cultivar LG 6036) grown in pots containing Oxisol in addition to tannery sludge vermicompost and irrigated with treated wastewater from households. The treatments consisted of factorial 2x6 (two types of irrigation and six fertilization treatments) in a completely randomized design with five replications. At the end of the experiment, the following production components were evaluated: 100 grain weight (g) (13% moisture -dry basis), total number of grains per spike, total weight of grains per spike and total weight of the spike (g). It was observed that plants grown in soil increased with tannery sludge vermicomposting and irrigated with treated wastewater had higher yields, which indicates that these residues are important sources of nutrients for growing corn.
