%X The leaching loss of NO 3 - N during wheat growing season in Piedmont Mountain Taihang are studied in this paper. The results show that there are lots of NO 3 - N leached during the wheat growing season in Piedmont of Mountain Taihang for the over fertilization and improper irrigation. The nitrate leaching through 180cm soil depth are 0 1kg/hm 2, 22 1kg/hm 2, and 110 1kg/hm 2 in wheat season with N 100kg/hm 2, 200kg/hm 2, and 400kg/hm 2 treatments, the irrigation before wheat planting and the first irrigation in the next year causes lots of nitrate leached.
