the subject innovation relates to an air supply and nutrients of the soil, and more particularly of soil physical three-phase non-that is, the solid phase ( ), liquid ( ), so as to keep the ratio of the gas phase ( ) at best, fresh air (oxygen) to the air in the soil can be smoothly supplied to provide the required nutrients in the soil and to a feeding device. A tree in saengyukji is embedded in ( ), for guiding air in the soil or the air supply and nutrients to the basement and the feeding device 10, is buried in saengyukji, incoming air and nutrients provides a path for the penetration into the soil nutrient supply to the air (11) Provided on one side end of the air supply nutrients 11 are exposed to the surface of saengyukji, riding surface horizontally flowing air was converted to the inclined direction of air leading to the air nutrient supply 11 supply guide portion (12) Provided at the other end of the air supply nutrients 11, the incoming air and nutrients and water discharge portion for discharging portion directly under (14) characterized in that it comprises a hayeoseo This devise is buried in saengyukji ( ) trees are vegetated by induction or facilitate the supply of air and nutrients into the ground, preventing soil loss ( ) and degradation ( ) of this with its own nutrients and, through them, and adjacent to the roots of trees and fresh supply air and without a rapid loss of valuable nutrients, can be another harsh urban environment through which to allow the growth of trees to reduce the mortality. Therefore, even in hazardous environments of the city is expected to contribute to the environment greener sikineunde record.본 고안은 토양의 공기 및 영양분 공급장치에 관한 것으로, 더욱 상세하게는 토양의 물리적인 삼상비 즉, 고상(固相), 액상(液相), 기상(氣相)의 비율을 최적으로 유지하도록, 토양에 신선한 공기(산소)를 원활히 공급시키고 필요 영양분을 공급시킬 수 있는 토양의 공기 및 영양분 공급장치에 관한 것이다.수목 생육지(生育地)에 매설되어, 공기 및 영양분을 지하로 유도 또는 공급하는 토양의 공기 및 영양분 공급장치(10)에 있어서, 생육지에 매설되어, 유입 공기와 영양분이 토양으로 침투되는 경로를 제공하는 공기영양분공급부(11) 생육지의 지상으로 노출되는 상기 공기영양분공급부(11)의 일측 단에 마련
