“…Because soil nitrification potential is positively correlated with both archaeal and bacterial amoA abundance (Sims et al, 2012;Song et al, 2010), the decreased abundance of ammonia-oxidizers in the intercropping and rhizobial inoculation treatments may be the explanation why intercropping can reduce nitrate leaching in soil (Whitmore and Schröder, 2007). Because it has been reported that the intercropping of cereals with legumes can reduce the nitrate but not ammonia accumulation (Huang et al, 2011;Li et al, 2005;Whitmore and Schröder, 2007), the decreased abundance of ammonia-oxidizers in the rhizosphere cannot be related to the reduction of ammonium concentration, so the real explanation for this decrease needs further study.…”

“…And for N210, the reasons might be both. Some studies showed that the yield had little response to N fertilization (Basso & Ritchie 2005, Li et al 2005. The difference may be a result of the disparity of initial soil NO 3 --N contents in different studies.…”

Conclusions. Nitrogen fertilizer application increased NO 3--N concentration and stock in 0-100cm soil profile and changed NO 3 --N distribution during maize cropping season. And nitrogen fertilizer application promoted movement of NO 3 --N down the soil profile and increased N loss. But effects of nitrogen fertilization application rate on above-ground dry matter production and grain yield were non-linear. Recommendations and Perspectives.A strictly controlled, site-specific, long-term fertilization study will be set up for the determination of biochemical processes of soil NO 3 --N and for the effective N fertilizer management of the saline soil areas. --N) accumulation is related closely to NO 3 -leaching, which is an important issue in groundwater pollution, especially in intensive agricultural areas with saline soils where volumes of water are used in irrigation to avoid salt accumulation in the root zone. However, in the saline environment in Hai River Basin, China, the importance of detailed research into NO 3 --N distribution in the root zone has not been adequately recognized. Considering the impacts of eco-environmental system N and crop production, the present study aimed at contributing to an understanding of the effects of N application rate on soil NO 3 --N distribution, NO 3 --N residue, N loss, and maize (Zea mays L.) yield in this region.

“…Therefore, the use of N fertilizer has increased dramatically in recent years (China Agricultural Yearbook 2001;FAOSTAT 2002). A number of investigations have been conducted in northern China to study loss and accumulation of NO 3 -N in the soil profiles under dryland farming systems (Yuan et al 2000;Fan et al 2000Gu et al 2003;Ju et al 2003Ju et al , 2004Liu et al 2003Liu et al , 2004Li et al 2003Li et al , 2005Wu et al 2003Wu et al , 2005. However, most of the reports have been published in Chinese with a short abstract in English, and do not provide enough information to international researchers.…”

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: 429Á440. 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. ( dans le sol, ainsi que ses conse´quences potentielles sur la contamination des eaux souterraines et superficielles, sous les terres arables arides du nord de la Chine. Ils abordent aussi les facteurs climatiques et agronomiques qui affectent la lixiviation du NO 3 ( . Il pleut relativement peu dans le nord de la Chine, mais l'intensite´des pre´cipitations et la porosite´du sol jouent un roˆle important dans l'accumulation du N-NO 3 et dans sa lixiviation subse´quente dans le sol. L'accumulation et la lixiviation de nitrates peuvent survenir quand on applique une grande quantite´d'engrais azote´s en vue d'accroıˆtre le rendement des cultures; la situation empire quand la vocation des terres passe de la ce´re´aliculture au maraıˆchage et a`la culture fruitie`re. En effet, dans de telles conditions, il peut y avoir contamination de la nappe phre´atique peu profonde par le NO 3 ( . On recommande de preˆter une plus grande attention a`la situation afin de pre´venir le proble`me par l'adoption de meilleures pratiques culturales, notamment en re´gulant la quantite´d'engrais azote´s employe´e, en recourant a`une fertilisation e´quilibre´e, en divisant les applications de N, en incluant des cultures aux racines profondes dans l'assolement et en minimisant la fre´quence des jache`res estivales (surtout sur sol travaille´).
