The effect of irrigation with magnetized water of varying salinity on some chemical properties of the soil and leachate of Kaskeis area (Aleppo governorate)

A column experiment was carried out under the conditions of the laboratory of colloids and clay minerals at the Faculty of Agricultural Engineering at the University of Aleppo, in order to know the effect caused by the magnetization of irrigation water on the chemical properties of soils irrigated with water of different salinity. The experiment was carried out on the Kskeis soil, located east of Aleppo city, and it was irrigated with three types of water of different salinity (Furat - Rasm Al-Hamis - Mishrifat Al-Zakiya). With irrigated water, the irrigation process was carried out with ten irrigations. The results indicated that the magnetization of showing off water reached its value, reached its value, reached its value, reached its value when magnetized. dS.m-1) was 4.05, while at the non-magnetized (dS.m-1) 3.7, the values of the sorbent sodium rate SAR were affected by the accumulation of salts in the subsurface layer of the studied treatments included in the study. The values of the rate of sodium adsorption SAR were also affected by the accumulation of salts in the subsurface layer of the studied treatments included in the study, and the magnetization of water contributed to the reduction of SAR values. 1.57, while it reached 1.93 in the same treatment irrigated with non-magnetized water.

The Effect of Irrigation with Sulfuric Saline Water on Some Majer Soil Properties and Productivity of Maize Crop

The research was conducted in order to study the effect of irrigation with sulfuric saline water on some major soil properties and maize production The flood irrigation process was carried out with four treatments: Treatment of witness was irrigated with fresh water, treatment No. (1) was irrigated with sulfuric saline water according to the standardized maize irrigation, and treatment No. (2) was also irrigated with salty sulfur water standardized for maize irrigation + 20% washing rate, and treatment No. (3) was irrigated with water Sulfur saline according to maize irrigation standard + 30% washing rate,The results of the study showed that there was a slight significant difference between the four treatments in terms of the apparent and real density, while there were clear significant differences between the treatments in terms of ESP%, EC and carbonates with depth, and this was the result of washing salts with the excess amount of irrigation water used for washing. The results also show that treatment No. (3) was the best of germination percentage and productivity, while treatment No. (1) achieved the lowest germination and productivity(Fresh maize cobs yield with wrappers) , as the readings were as follows: The percentage of germination in the witness was 95%, in treatment (1) 90%, and in treatment (2) 95% and in treatment (3) 97%, while the productivity was in the witness 32.4 tons / ha and in treatment (1) 30.25 tons / ha and in treatment (2) 33.6 tons / ha and in treatment (3) 39.037 tons / ha. This indicates that irrigation with sulfuric saline water according to (water ration for maize + 30% washing) achieved the best results, as the economic feasibility of using sulfuric saline water was achieved by obtaining good production, providing fresh water and preserving the major properties of the soil.

The Effect of Irrigation with Magnetized Water of Varying Salinity on Some Physicochemical Properties of Gypsiferous Soils in the Maskana (East of Aleppo Governorate)

A column experiment was carried out under the conditions of the laboratory of colloids and clay minerals at the Faculty of Agricultural Engineering at the University of Aleppo. The aim of study is know the effect caused by the magnetization of irrigation water on the physicochemical properties of soils irrigated with water of different salinity. The experiment was carried out on selected gypsiferous soils from the village of Musharafa Al-Zakiya located in the Maskana project (Aleppo governorate). And it was irrigated with three types of water of different salinity (Euphrates River water -Rasm Al-Hamis village - Musharafa Al-Zakiya village). Irrigation technology was applied With magnetized water (M) and water without magnetization (NM), a leaching factor of 15% was used with water added to the columns, and the irrigation process was repeated ten times. The results indicated that the use of the water of Rasm Al-Hamis well and the well of Mishrifa, the magnetic purity, contributed to the washing of salts by 20% and 16% for the surface and subsurface layers, respectively, compared to similar treatments irrigated with normal water, and the results of the statistical analysis indicated that the decrease in the concentration of salts in the washed columns The magnetized water was significant. As for the magnetized water of the Euphrates, it contributed to the washing of salts from the surface layer within the soil columns by about 5.5%, compared with the treatment irrigated with non-magnetized Euphrates river water, and the decrease in the concentration of salts was not significant. The data indicated in general to the significant role of the washing coefficient applied in this study in the disposal of salts, in particular soda salts, as the data showed that the magnetization of water added to the studied soil columns contributed clearly in reducing the values of the adsorbed sodium ratio (SAR) and the ratio of exchangeable sodium (ESP) compared to the non-magnetized irrigation water. The magnetization of water also contributed to improving the porosity of soil irrigated with magnetized water, compared to treatments irrigated with ordinary water.

Dissolved Nutrients Behavior Along The Salinity Gradient At The AL-Kabir Alshemali River Mouth (Mediterranean - Syria)

The study, has Focused on determination of the most important hydrochemical characteristics of water at AL-kabir alshemali estuary area by determination the concentration of nutrient ions (nitrate, nitrite, ammonia, phosphates and silicates) and the factors affecting them. Water samples were collected from several stations of that area between March 2017 and January 2018. The highest concentrations of nutrient throughout the year were reported at river estuary point (K0), a depression in their concentrations was observed in the station distanced away from the river estuary point, compatible with salinity gradient. River estuary point (K0) formed the main source of nutrients that are distributed to other stations. Nutrient concentrations showed clear gradual depression in winter down to more than 1,000 meters from the estuary point, while the gradient in summer has less extension, It was within the first 50 meters in some monthes.

Modelling the drinking Water Turbidity of Al-Sin Purification Plant using Dynamic Neural Networks

Modelling the relationship between drinking water turbidity and other indicators of water quality in Al-Sin drinking water purification plant using Dynamic Artificial neural networks could help in the implementation of the stabilization for the performance of the plant because these neural networks provide efficient tool to deal with the complex, dynamic and non-linear nature of purification processes. They have the ability to response to various instant changes in parameters influencing water purification. In this research, four models of feed-forward back-propagation dynamic neural network were designed to predict the effluent turbidity from Al-Sin drinking water purification plant. The models were built based on turbidity, pH and conductivity of raw water data while the effluent turbidity data were used for verify the performance accuracy of each network. The results of this research confirm the ability of dynamic neural networks in modeling and simulating the non-linearity behavior of water turbidity as well as to predict its values. They can be used in Al-Sin drinking water purification plant in order to achieve the stabilization of its performance.

Removing of Heavy Metals from Sewage Water Using Chitosan Extracted from Crustacean Waste

The biological role of chitosan which was prepared by chemical method from shrimp waste Penaeus semisulcatus and the outer skeleton for marine crab Portunus pelagicus in some industrial and agricultural applications were studied. The concentration of prepared chitosan was 1% (w/v) at pH (4 and 8) for 12 hours in precipitation and chelating heavy metals (Lead, Zinc, Iron, Cupper and Cadmium) from of sewage water. Concentration of elements was measured by Flame Atomic Absorption Spectrophotometer ) FAAS). The results of the study indicated that the concentration of the water elements was high before treated with chitosan. The results showed a significant (p<0.05) decrease in element concentration percentage after treated with crab chitosan. In contrast, shrimp chitosan displayed a minimum effect on decreasing the amount of heavy metals. Moreover, the results showed that the higher percentage for mineral adsorption was at pH (4 as compared with 8). The results confirmed the possibility of using chitosan in chelate and precipitate the mineral ions from polluted water.
