Mazkur maqolada tuproq organik moddasining (TOM) tarkibi, uning fraksiyalari hamda agroekotizim unumdorligiga ko‘rsatadigan ta’siri tizimli yondashuv asosida tahlil qilindi. Organik moddaning faol va barqaror fraksiyalari mikrobiologik transformatsiya jarayonlari orqali oziqa elementlar aylanishini boshqarishi hamda organo-mineral komplekslar hosil qilishi ilmiy adabiyotlar asosida asoslab berildi. Tadqiqot natijalari shuni ko‘rsatadiki, TOM tuproqning agregat barqarorligi, kation almashinish sig‘imi, suv rejimi va mikrobiologik faolligini belgilovchi asosiy omil hisoblanadi. Organik modda zaxirasining kamayishi degradatsion jarayonlarni kuchaytirib, hosildorlikning pasayishiga olib keladi. Shu bilan birga, TOM uglerod sekvestratsiyasi jarayonida muhim rezervuar sifatida iqlim barqarorligini ta’minlashda ham ahamiyat kasb etadi. Barqaror agrotexnik tadbirlar orqali tuproq organik moddasini boshqarish yuqori va uzoq muddatli hosildorlikni ta’minlashning asosiy strategik yo‘nalishi sifatida baholandi.
