Aims: In the long run, reusing low-quality water in Egypt's agricultural sector directly or after mixing with fresh water to compensate for water supply constraints can be hazardous to plants and soil. As a result, some appropriate management must be considered. For this reason, a field experiment was implemented in winter seasons 2018/2019 and 2019/2020 at Sakha Agric. Res. Station Farm, Kafr El-Sheikh Gov., Egypt. This study aims to assess the impacts of zeolite and vermicompost as well their combinations on alleviation of low-quality water impacts on physicochemical properties of clayey soil and wheat productivity. Study Design: complete randomized block design with three replicates. Results: The application of 2.40 Mg Z ha-1 was found to be the most effective on soil properties and plant growth. This treatment reduced soil EC, Na+, Ca2+, Mg2+, Cl-, SO42-, and ESP values the most (52.90 percent, 83.21 percent, 30.43 percent, 6.04 percent, 91.82 percent, 19.83 percent, and 70.73 percent, respectively), while increasing the K+ value by 32.47 percent. It also achieved the highest increases in plant height, 1000-grain weight, grain, and straw yields (35.92%, 9.60%, 42.77%, and 25.61%, respectively) when compared to untreated soil. With 2.40 Mg VC ha-1, the greatest changes in bulk density, total porosity, and CEC (-9.23, 9.30, and 10.54 percent, respectively) were obtained. The applications of 1.80 Mg Z with 0.6 Mg VC ha-1 and 0.6 Mg Z ha-1 with 1.80 Mg VC ha-1, on the other hand, resulted in the greatest increases in soil moisture content, drainable pores (DP), and water holding pores (WHP). Furthermore, 0.6 Mg Z combined with 1.80 Mg VC ha-1 significantly increased the available N, P, and K in the soil. The addition of 2.4 tons Z/ha increased the WP and resulted in a high economically appealing wheat. Conclusion: It could be concluded that the application of Z and VC is a new strategy for alleviating abiotic stress and improving wheat growth. Z application was more effective than VC on improving soil physicochemical properties and improving the water productivity and achieve high economical attractiveness wheat irrigated by low-quality water.

Sustainable development goals (SDGs) 2 (zero hunger), 6 (clean water and sanitation), and 15 (life on land) are related to the human-water-soil nexus. Soil organic carbon and nutrients can be removed and transported to waterways through runoff and drainage. The main goals of this study are to quantify the water quality for irrigation and assess the dissolved organic carbon (DOC) contents in streams in the northern Nile Delta, Egypt. A 4-year water quality monitoring program is accomplished by collecting 35 irrigation and drainage water samples per year from the study area. The measured water quality parameters are as follows: salinity, pH, Na, SAR, Cl, and NO3–N. In addition, the DOC content is accessed. The salinity hazard ranged from moderate, for most irrigation samples, to high and very high for drainage samples. All collected water samples have low to medium sodium hazards. Results indicate that average DOC contents in irrigation canals are 2.32 and 2.93 mg L−1 for the summer and winter, respectively. The respective means of DOC concentration in drainage canals for the summer and winter seasons are around 3.96 and 5.09 mg L−1. This study revealed significant differences in EC, pH, Na, Cl, and SAR, as water quality parameters, between irrigation and drainage canals. Additionally, the studied agroecosystem has seasonal variability in DOC concentration in irrigation and drainage canals between summer and winter. Overall, reusing drainage water for irrigation in the study area requires the selection of suitable crops and site-specific management.
