Abstrak
Ushbu maqolada suv toshqini natijasida tekislik hudud tuproqlarida yuvilish darajasi ortgan sayin tuproqning gumus va oziqa elementlari miqdori ham mos ravishda kamaygan. Tuproq unumdorligini qayta tiklash uchun suv toshqini natijasida yuvilgan sug‘oriladigan bo‘z-o‘tloqi tuproqlarga organik va mineral o‘g‘itlar bilan birga qo‘llanilgan. Qisqa fursatda unumdorligini qayta tiklashinishi natijasida tuproq xossalari, g‘o‘za o‘simligini koʼrsatgichi bayon etilgan. Natijada dala tajriba maydonining g‘o‘za vegetatsiyasi tugagandan keyin yuqori ko‘rsatgichdagi olingan tuproq namunalarida ya'ni zoogumus qo‘llanilganida 0-30, 30-50 smli qatlamlarda gumus miqdori 0,576-0,733%, harakatchan fosfor 23,6-41,6 mg/kg, almashunuvchi kaliy 228-277 mg/kg o‘zgarganligi aniqlandi.
