Dunyoda aholining o'sishi va iqlim o'zgarishlari oqibatida suvdan foydalanish hajmi ortib borayotganligi sababli, qishloq xo'jaligida suv resurslarini tejash dolzarbligi ortmoqda. Tuproq ichidan sug'orish (subsurface irrigation) texnologiyasi zamonaviy irrigatsiya usullari orasida eng samarali yechimlardan biri hisoblanadi. Ushbu maqolada tuproq ichidan sug'orish tizimining konstruksiyasi, ishlash prinsipi va boshqa an'anaviy sug'orish usullari bilan solishtirilgan holda samaradorligi chuqur tahlil qilingan. Tahlil natijalariga ko'ra, tuproq ichidan sug'orish usuli yuzaki sug'orishga nisbatan suv sarfinin 30-55% kamaytirish, suv samaradorligini 2-3 barobar oshirish va o'simlik ildiz tizimini rivojlanishini yaxshilash imkonini beradi. Maqolada, shuningdek, tuproq namligining chuqurlik bo'yicha taqsimoti, suvning yo'qotilish yo'nalishlari va iqlim sharoitlarining ushbu texnologiyaga ta'siri tahlil qilingan. Tadqiqot natijalari asosida amaliy tavsiyalar ishlab chiqilgan va kelajak tadqiqot yo'nalishlari belgilangan.
