Abstract: By analysis the change of nitrate-nitrogen's contents in different soil layers during corn season and the change of the water content in the soil,we studied the leaching of nitrate-nitrogen during corn season.The results showed there had nitrate-nitrogen leaching during the corn season in Piedmont of Mountain Taihang.The nitrate-nitrogen move downward into the deep layers along with the water's percolation,and the leaching of nitratenitrogen were 2kg/ha in 200kg/ha treatment,16kg/ha in 400kg/ha treatment,50kg/ha in 800kg/ha treatment.The first and second irrigations had the most important role in the redistribution of nitrate-nitrogen,they made the nitrate accumulated in the 40-160cM soil layer.

Key words: Nitrate-nitrogen leaching, Water balance, Mountain Taihang piedmont
