Purpose: A comprehensive monitoring and evaluation study was conducted on wells, water table and drainage water for water quality index. The study aimed to achieve a sustainable integrated management for water and soil at the study area. Methodology: Assessment and evaluation of water samples were: Evaluate the physic- chemical properties; Discuss the Hydro chemical coefficient; Assessment of the appropriate use of water quality such as permeability index (PI) and Kelly's indicator (KI); Water quality identification and assessment through calculate of WQI;  It was conducted various assessments of the elements within the water, such as the contamination factor (CFi); geo-accumulation index (Igeo) and the potential ecological risk index (RI).   Findings: The results shown that the dominance of Na+ cation and Cl- anions due to the influence of marine sediments on water elements which resulted in increased the mention  ions in drainage water> water table> wells. TDS values of wells, water tables and drainage water were no detected, 2374 to 9088 and 3641.6 to 13952mg L-1, respectively and RSC values of water samples were not significant. KI indicated that the well water is safe for drinking and the water table and drainage water are not acceptable for drinking. PI indicated that the suitability of water to be used in agriculture. WQI confirmed that the water is highly appropriated for Olive's tree and Palms cultivation. CFi indicated that the wells gave low to moderate contamination of Mn, Cu and B while, the Fe, Zn and Si concentrations were low. A very high degree of contamination by Fe, Mn, Zn, Cu and B were observed in water tables; however Si concentration was low to considerable degree. Generally, drainage water gave a very high degree of contamination with Mn, Cu, and B, whereas the concentration of Fe, Zn and Si were low, moderate and considerable degree. Analytical modeling proved that the Igeo values for Mn, Zn, Cu and Si were assigned to Class 0 for water sources at study area. RI indicated the wells and water table samples (exception of Cu was moderate to high) were slightly risk as well as the RI of drainage water samples was low risk. Contribution to theory, practice and policy: The results provided the relationships between the water resources assessment and water quality management, and to ensure their environmental reflections such as (contamination factor (CFi); geo-accumulation index (Igeo); the potential ecological risk (RI)), with the safe use of water based on its properties. Keywords: Hydro chemical coefficient; permeability index (PI); Kelly's indicator (KI); water quality index (WQI); contamination factor (CFi); geo-accumulation index (Igeo); the potential ecological risk (RI).

In Egypt, the soil salinity is the mainly constraint to the development of agricultural sector. In the last few decades, the farmers and the government have made a great effort to diminish the hazard of soil salinity. The resistance of soils to salinity processes by human positive actions is known as soil resilience. This study aims to assess the soil salinity and resilience at north of Nile Delta and evaluate their impact on macro nutrients uptake by wheat plant. To fulfill these objectives, (i) field survey for identifying the main soil physical and chemical properties as well as the nutrients status in soils of the study area were carried out, (ii) explore the effects of salinity on the macronutrients uptake and ionic relations, and to (iii) status of macronutrients in soils and wheat plant in salinity environments. The results showed that the textural classes of these soils were clay were determined in cultivated land. In addition, The CEC range between 26.49 to 33.03Cmolc kg -1 , total CaCO3 was range between 0.91 to 3.04 % and the gypsum was range between 1.69 to 5.64 %. The dominant soluble cations were Na + followed by Ca +2 and Mg +2 while K + was rather low in a descending order. On the other hand, soluble anions were dominated by Cland SO4 -2 . Results on correlations of EC with macronutrients in the soils, it gives strong positively correlation and regression of EC constant with available macronutrients. The present study confirms that at all salinity levels the variation in germination, plant growth, dry matter accumulation, ionic strength and availability of nutrients in seeds and straw could be better explored in determining the tolerance capacity of the wheat cultivars.

The recent soil fertility evaluations are evidence of the serious development challenges that many agricultural regions in Egypt; and with growing food demand, soil evaluation will become even more important for the regions in the coming years. The soils studied revealed that the highest ions concentration measured in soil paste extracts were Na + and Clions. The soil pH could be categorized as slightly to moderately alkaline. Alkaline soils, that have ESP more than 15% and high pH values. In general, most soils were relatively sandy loam. Else, CEC of the soils in the study area was between 3.16 to 24.96 cmolc kg -1 . Most soil study high content of CaCO3 and considered as very slightly; slightly; moderately and highly gypsiferous. Data indicated that the available macro and micronutrients in the study area are low. Also, the exchangeable cations were significantly affected by recently environmental changes. This study was undertaken to investigate the spatial variability of selected soil properties using SFI modeling. Up to on the quantitative evaluation of SFI using spatial variability of soil data and modeling techniques is a very important operation. SFI in our study area is very poor fertility (S4= <20) according to classes and values of SFI. Pearson correlation coefficient was calculated to determine the significant positive correlation among SFI and soil pH; EC; CaCO3; OM; total N; available of P, Fe, Mn and Cu; exchangeable of Ca, Na and K. In addition, the SFI is insignificantly and positively correlated with available Zn and exchangeable Mg.
