Ushbu maqolada vegetatsiya tajribalari asosida og‘ir metallar bilan sun’iy ifloslantirilgan sug‘oriladigan tipik bo‘z tuproqlarda yetishtirilgan Alanga va Lazurniy sholi navlari ta’sirida og‘ir metallarning harakatchan shakllari miqdorining kamayishi tahlil qilingan. Tadqiqotlar natijasida 2021-2023-yillar davomida Cu, Pb, Ni, Cd, Cr, Co va Zn elementlarining harakatchan shakllari barcha tajriba variantlarida kamaygani aniqlandi. Lazurniy navida eng katta kamayish Zn (102,03-45,08 mg/kg), Pb (31,23-13,80 mg/kg) va Cr (16,85-7,44 mg/kg), Alanga navida esa Zn (82,19-42,01 mg/kg; 40,18 mg/kg), Pb (29,61-15,14 mg/kg; 14,47 mg/kg) hamda Cr (21,14-7,15 mg/kg; 13,99 mg/kg) elementlarida qayd etildi. Olingan natijalar har ikkala sholi navining og‘ir metallar bilan ifloslangan tuproqlarni fitoremediatsiya qilishda samarali ekanligini ko‘rsatdi.
