“…The used modeling approach was based on the simulation of the overall salinity. An alternative geochemical approach that considers the multicomponent solute reactions and transport (as implemented in the Unsatchem module of HYDRUS-1D [12]) for the calculation of soil electrical conductivity may be more appropriate for optimizing the management of irrigation with highly saline waters [11,39].…”

“…Irrigation with saline waters generally results in salinization of the topsoil [4][5][6], and, in the long term, salts leaching under the effects of rainfall can contaminate groundwater [7,8]. On the other hand, multiple authors have shown that the salinization phenomenon in the topsoil can be cyclic, and the effect of salinity on crops can be attenuated with proper management that involves appropriate irrigation for salt leaching [9][10][11]. However, in arid regions, reduction in agricultural water use is part of the water resource management policy.…”

In Tunisia, water used for irrigation is often saline, increasing the risk of salinization for soils and crops. In this study, an experiment was conducted on a tomato crop cultivated on a silty-clay soil irrigated with three different water qualities: 0, 3.5, and 7 dS·m−1. Experimental data were then used to calibrate and validate the Hydrus-1D model, which simulates water flow and salt transfer in soils. The successfully-calibrated and validated model was then used to study the combined effects of the soil osmotic and soil matrix potentials on root water uptake. The values of the root mean square error (RMSE), the coefficient of determination (CD), the modeling efficiency (EF), and the coefficient of residual mass (CRM) were close to their optimal values for both soil water content and soil electrical conductivity profiles, indicating the reliability of the model to reproduce water and salt dynamics. Relative yields (Yr), indirectly estimated using actual and potential root water uptake (transpiration), indicated that the multiplicative stress response model (using the S-shape model) satisfactorily simulates measured yields and reproduces the effects of irrigation with saline waters on crop yields. An alternative scenario using a reduction of water requirements by 50% was investigated to assess an irrigation method with considerable water savings. As the results show that relative yields, Yr, were only slightly reduced, the crop water requirements estimated by CROPWAT 8.0 must have been overestimated. The variation of the soil salinity in the root zone highlighted a high salinization risk in the short-term when water of 7 dS·m−1 is used for irrigation.

“…At location I the Na content is only 2.65 cmol (+) kg −1 , while at locations II and III the coastal sediment contains Na respectively 36.03 and 34.85 cmol (+) kg −1 , respectively. The Na content of 15 times from coastal sediment in location I is dangerous because Na has a bad effect on several soil properties [11]. Thus, in the use of coastal sediment from locations II and III, it is necessary to reduce Na by washing so that the Na content is lower.…”

Coastal sediment is a sediment resulting from sedimentation of eroded materials from up land through river flows that are deposited around the coast. It usually contains a lot of alkaline cations, especially Na so that it is good enough to decrease soil acidity. The use of coastal sediment must be considered carefully because it has a high level of salinity, which can inhibit plant growth and even cause death. Coastal sediment as an ameliorant can replace the role of lime in increasing the pH and base saturation of soil. Applying coastal sediment to sandy or post-gold mining soils can reduce soil acidity, increase soil CEC and soil base saturation, as well as the availability of nutrients, especially nutrients, phosphorus, potassium, calcium and magnesium. Improvement of some of these soil properties will encourage increased growth and crop yields in post gold mining land.

“…Soil water quality is defined by physical, chemical, and biological characteristics. Water quality problem in irrigated agriculture from soil water for an instant from water infiltration rate is relatively excessive sodium or lack of calcium in water or soil will reduce the rate of absorption, which results in plants becoming lack of water adequately from one irrigation to the rest [13]. There are several factors to be considered of water quality for irrigation, such as pH, EC and TDL and TSS.…”

Indonesia has two seasons. These are wet season and dry season; in the dry season, water from rainfall decreases and demand for water as irrigation resources decrease. Soil water is expected to supply irrigation in the agriculture sector. Water quality at Universitas Padjadjaran can be affected by poor water disposal planning and the location of the surrounding industrial estate, animal farms, farm activities and domestic wastewater. Poor water quality can affect the quality and quantity of crops. Melon is commonly not needed much water as a consumptive use but needs water in whole life and usually applied irrigated, especially if growth in the greenhouse. Poorly applied water qualities of the melon can will impact the quality and quantity to decrease. Research on the impact of soil water quality on yield and quality and consumptive use of melon was conducted at the greenhouse located in Universitas Padjadjaran Campus, West Java Province, Indonesia, from July to November 2019. The research method is descriptive analysis, and melon is planted in containers called autopot and fertigation daily applied by control of autopot smart valve. The results show that TSS of soil water were 200.2 mg/al; TDS 300.2 mg/L; EC 0.75 mS/cm; pH 7,0 and turbidity is 4.75 NTU. The quality of melon shows that water 95.19%; Fat 0.88%; ash 0.57%; protein 1.37%; carbohydrate 1.99% vitamin C 6.91% and sweeteners is 9.4 Brix. In conclusion, that soil water meets requirements as resources irrigation to applied melon.
