Abstrak

Ushbu tadqiqot Orol dengizining qurigan tubida shakllangan qoldiq– botqoq tuproqlarning fizik-kimyoviy qatlamlanishi va sho‘rlanish dinamikasini baholashga bag‘ishlangan. Tadqiqotlar Orolbo‘yi pasttekisligining “0” nuqtasida joylashgan tajriba maydonlarida 0–200 sm chuqurlik bo‘yicha olib borildi. Natijalar tuproq profilida tuzlarning notekis taqsimlanganligini ko‘rsatdi: 0–45 sm qatlamda o‘rtacha va kuchli sho‘rlanish ustun bo‘lib, sho‘rlanish turi asosan xlorid–sulfat va magniy–natriy xususiyatiga ega. Quruq qoldiq va eruvchan ionlarning maksimal to‘planishi 0–2 sm hamda 22–29 sm qatlamlarda qayd etildi, bu bug‘lanish va grunt suvlari kapillyar ko‘tarilishi bilan izohlanadi. Almashinuvchi kationlar tarkibida Mg²+ va Na+ ustunligi tuproqning gidromorf sharoitda shakllanganligini ko‘rsatadi. Olingan natijalar Orol dengizi qurigan tubida tuproq degradatsiyasini baholash va rekultivatsiya choralarini ishlab chiqishda muhim ilmiy ahamiyatga ega.
