METHOD OF LAYING SUBSURFACE MOISTENING NETWORK Russian patent published in 2000 - IPC

FIELD: amelioration, in particular, subsurface irrigation systems. SUBSTANCE: method involves cutting slits in soil and laying distributing-and-moistening network; forming lower mark of each slit as mirror pattern of piezometric pressure along moistening network, so that slit depth at the leading and tail ends of straight part is 50-55 cm, and at distance making 0.6-0.7 of its length from leading end - it is 35-40 cm. Such laying of subsurface moistening network provides for uniform pressure along slits. EFFECT: increased efficiency by uniform moistening of soil. 2 dwg
