 The study examined the effects of increasing salinity of irrigation water on the nutritional content of leaves from five different soil types. Results showed that higher levels of salinity resulted in higher concentrations of macronutrients such as nitrogen, potassium, and magnesium in all soils tested. However, some micronutrient levels were affected by the increased salinity, including copper in one type of soil, iron in two types of soil, and manganese in two types of soil. Overall, this study provides valuable insight into how increased salinity affects the nutrition of crops grown in different soil types.
