Soil pH and salinity significantly affect plant biogeochemical safety, ionome, and nutritional balance. Under such conditions, we established local compositional nutrient diagnosis standards using the centered log ratio (CNDclr*) means and standard deviations of the ionome from high-yield and nutritionally balanced ‘Sirvan’ wheat specimens (Triticum aestivum L. var. ‘Sirvan’). Critical nutrient indices (I2 X) and the critical yield of the wheat fields were determined based on the Cate-Nelson method. The Cate-Nelson model indicates that for yields above 6974.9 kg/ha, the CNDr2 index value must be below 17.645. According to clr indices the most critical leaf nutritional indices influencing the performance of low-yield ‘Sirvan’ wheat fields on calcareous and saline soils were identified. Among the leaf nutrient indices in low-yield populations of ‘Sirvan’ wheat fields, increasing leaf Ca, P, Mn, Cu, N, and Zn, while decreasing Mg, B, and K, and bringing them closer to zero within the range of nutritional balance, can have significant effects on yield under saline and calcareous soil conditions, countering the negative impact of high pH due to alkaline salt stress.
