PROBLEM TO BE SOLVED : To provide a soil managing method efficiently performing scattering or infiltration of liquid into real soil.
SOLUTION : This soil managing method which controls movement of liquid in soil includes dropping or spraying liquid from a ground surface so as to bring a value of a supply rate to less than one-tenth of a previously measured saturated hydraulic conductivity of objective soil. The method can avoid selective liquid movement to macro pores even in real soil where macro pores such as indicative marks of plant roots and living marks of insects and other underground organisms exist, and achieve scattering or infiltration of liquid into earth and sand intervals held by capillary power, i.e., micro pores.
