| 英文摘要 | Fan, J., Hao, M. and Malhi, S. S. 2010. Accumulation of nitrate-N in the soil profile and its implications for the environment under dryland agriculture in northern China: A review. Can J. Soil Sci. 90: 429-440. Nitrate (NO(3)(-)) leaching and water contamination have become a worldwide concern. In this review, some examples are presented to show the extent and magnitude of NO(3)(-)accumulation in the soil profiles and its potential effects on contamination of ground water and surface water under dryland farming in northern China. Climatic and management factors affecting NO(3)(-) leaching are also discussed. In northern China, rainfall is relatively sparse, but the high intensity of precipitation and porous soils play an important role in the accumulation of NO(3)-N in soil and its subsequent leaching in the soil profile. There is a risk of nitrate accumulation and leaching when high rates of fertilizer N are applied to improve crop yields, and it becomes even worse when conventional land use is changed from cereal crops to vegetable crops and fruit orchards. Under such conditions, shallow ground water might be polluted by NO(3)(-). This suggests that more attention should be paid to prevent this problem by using best management practices, especially by controlling the amount of N fertilizer input, balanced fertilization, split N application, inclusion of crops with deep taproots in the rotation and minimizing summer fallow (especially tilled) frequency. |
