gumus, kimyoviy ifloslanish, taqir-o‘tloqi, o‘tloqi-allyuvial, umumiy azot, fosfor, kaliy, pH, C:N nisbati, sanoat ifloslantiruvchilari,

Abstrakt: Ushbu tadqiqotda sanoat korxonalarining kimyoviy ifloslantiruvchilari, jumladan og‘ir metallar va boshqa toksik birikmalarning avtomorf va gidromorf tuproqlarning asosiy fizikkimyoviy xususiyatlariga ko‘rsatgan ta’siri kompleks tahlil qilindi. Tadqiqot Navoiy viloyatidagi yirik sanoat obyektlari – Sement zavodi, Navoiy Azot AJ, NKMK va GREES atrofida joylashgan taqir-o‘tloqi hamda o‘tloqi-allyuvial tuproqlarda olib borildi. Natijalar shuni ko‘rsatdiki, kimyoviy ifloslanish darajasi ortgan sari gumus miqdori va oziqa elementlarining tarkibida sezilarli o‘zgarishlar kuzatiladi. Xususan, sanoat obyektiga yaqin qatlamlarda gumus miqdori 0,91–1,09% oralig‘ida bo‘lsa, 20 000 m uzoqlikdagi FON hududida ushbu ko‘rsatkich 1,41% gacha oshadi. Umumiy azot va fosfor konsentratsiyasining pasayishi ham kuzatilgan. Gumus va azot o‘rtasidagi yuqori muvofiqlik (C:N nisbati 7–8) tuproqdagi organik moddalarning parchalanish darajasi hamda biologik faollikni baholash uchun muhim indikator sifatida tavsiya etiladi
