Abstract:: By simulating soil column in laboratory, the effects of the nitrate vertical transport characteristics in the gneiss of Taihang mountainous region of Hebei Province under different N fertilizer were studied. The results showed that the ratio of leaching loss amounts of nitrate-nitrogen was 1∶0.87∶0.94 among urea, organic-inorganic mixed fertilizer and N-P compound fertilizer. The amount of nitrate leaching increased with the increasing amount of nitrogen fertilizer, but there was no significant difference among the three fertilizers. Organic-inorganic mixed fertilizer could reduce nitrate leaching with the medium nitrogen fertilizer application. For urea, the rate of nitrate leaching loss averaged 29%, 27.8% for N-P compound fertilizer, 23.7% for organic-inorganic mixed fertilizer. With the increase of soil depth, there was no significant difference between 60 cm and 90 cm in which the ratio of nitrate-nitrogen leaching loss was 1∶1.03. At the end of the leaching, the nitrate content of organic-inorganic mixed fertilizer was the highest and the urea nitrate content was the lowest in different treatments.
