First the application of saline water will affect the soil pH which reduces the availability of several micro nutrients like Zn, Fe, Mn etc. The development of salt crust in soil due to continuous application of salty irrigation water also creates obstruction to nutrient movement in soil, thus plant roots are unable to extract the soil nutrients. Most importantly, the presence of sulphates ion in salty water favours leaching of micro-nutrients with irrigation water which promotes nutrients loss and reduces their availability to plants.

The concept is very simple. Decreasing pH leads to increasing toxicity of soil micronutrients except molybdenum. Increasing pH leads to deficiency of micronutrients except molubdenum. Saline conditions occur side by side with alkalinity in soils especially in dry areas.

So your case will lead to micronutrient deficiency

Salt water increases osmotic pressure and thus prevents water absorption and prevents the absorption of the nutrient and is a competition for the nutrient

micro nutrient having cationic property affected by the presence of chloride and sulphates of calcium and magnesium due to the presence of cationic property of the saline water which will not permit to uptake or absorb. if you add any material (organic ) to production of anionic material or leach out the cationic salt present in the soil.

Salt water affects the availability of micronutrients which in long-run affects the macronutrients absorption thus affecting health of plant

Nutrient uptake and use efficiency in salt affected soils is low due to salt stress and negative interactions with cations and anions present in high concentrations. Hence, a higher amount of nutrients is necessary in salt affected soils compared to normal soils. There are many soil factors influencing micronutrient solubility and availability for plants. The most important of these factors are pH, organic matter content, CaCO3, soil texture, cation exchange capacity, erosion, soil moisture and temperature etc. Moreover, salinity reduces the uptake of nutrients, accumulations or even affecting the nutrient partitioning within the plants or may be caused by physiological inactivation of a given nutrient resulting in an increase in the plant's internal requirements for the that essential element . One of the main consequences of high concentrations of Na+ and Cl- is the negative effect on the absorption and/or use of several essential nutrients. The logic is that the mechanisms of absorption, transport, and use of the nutrients could not operate efficiently when they are grown under salt stress. If the soil is irrigated with saline water, the cation exchange capacity of soil becomes concentrated with Sodium creating a sodic soil. The availability of N, P and K nutrients was reduced with the increasing salt concentration due to the highest immobilization of ions to the soil.Saline soils have many physical changes in them as compared with normal healthy soils. These soils have low biodiversity and are known to be dead soils. They have nutrient deficiencies and toxicities because of boron, carbonate, and aluminate ions present.
