Abstrak
Ushbu maqolada Quvasoy sement zavodi ta’sir zonalarida joylashgan sug‘oriladigan tipik bo‘z tuproqlarda ishqoriy (Na, K, Rb, Cs) va ishqoriy-yer (Ca, Sr, Ba) metallarining geokimyoviy xususiyatlari o‘rganildi. Tadqiqotlarda sement zavodidan 100, 500, 1000 va 10000 m (fon) masofalarda joylashgan tuproq kesmalarining turli genetik gorizontlari va chuqurliklaridan namuna olindi. Ishqoriy va ishqoriy-yer metallarning miqdoriy o‘zgarishi fon hududiga nisbatan 100-500 m zonalarda nisbatan yuqoriligi bilan ajralib turdi. Ayrim elementlarning (K va Ca) tuproqning yuqori qatlamlarida, zavodga yaqin hududlarda texnogen to‘planish tendensiyasi aniqlandi. Na, Rb va Cs elementlarining taqsimoti texnogen omildan ko‘ra sug‘orish sharoitlari, agrotexnik tadbirlar va tuproq hosil qiluvchi ona jinslarning mineralogik tarkibi bilan kuchliroq bog‘liq ekani ko‘rsatildi.
