Abstract
This study investigates the distribution and concentration of cyclic elements in irrigated typical gray soils formed in the Shahimardonsoy alluvial fan of Southern Fergana. Field research and geochemical analysis were conducted using morphogenetic and comparative-geographical methods, along with systematic pedogeochemical approaches. The findings reveal a twofold increase in iron content within the geochemical carbonate-illuvial barrier, which also acts as an accumulation zone for other macroelements such as K, Na, Cr, and Sr, as well as cyclic microelements including Mn, Co, and Hf. These results indicate that irrigation significantly influences the migration and redistribution of elements in soil profiles, impacting soil fertility and agricultural productivity.
