The invention relates to a farmland nitrogen loss lateral-seepage collecting device. The farmland nitrogen loss lateral-seepage collecting device is characterized by being provided with a collecting box vertically inserted into farmland soil, and the collecting box is formed by a rectangular housing on the upper portion of the collecting box and a reservoir arranged at the bottom of the collecting box and surrounding the bottom edge of the housing to be integrally connected with the housing; one longer side face of the housing is arranged to be a filtering and permeating layer; the cross section of the reservoir is an inverted trapezoid; a vent pipe hermetically connected with the housing and vertically inserted into the upper side in the housing and a leading pipe inserted to the bottom of the reservoir are respectively arranged at the top face of the housing, and one end, outside the housing, of the guiding pipe is connected with a suction device; the housing is 0.3-0.4m in height, the reservoir is 0.4-0.5m in depth, and the rectangular housing is dimensionally 1:0.3-0.4:0.3-0.5 in the length to the height to the thickness. The farmland nitrogen loss lateral-seepage collecting device has the advantages of small size, easiness in motion, convenience in operation, simplified lateral-seepage collecting process, small investment and quick results.
