| 1 | Estimating total nitrogen deposition in agroecosystems in northern China during the wheat cropping season显示文摘Atmospheric nitrogen (N) deposition has been poorly documented in northern China, an intensive agricultural and industrial region with large emissions of NHx and NOy. To quantify N deposition, total airborne N deposition was determined at three agricultural sites using a manual integrated total nitrogen input (ITNI) system during growth of winter wheat (Triticum aestivum L.) and Italian ryegrass (Lolium multiflorum Lam.) from September 2005 to May 2006. Total estimated N deposition averaged 54.9 and 43.2 kg N/hm2 across the three sites when wheat was grown to flowering and maturing, respectively. The average value was 50.2 kg N/hm2 when ryegrass was the indicator plant. Both indicator species gave similar total airborne N input results. The intermediate level of N supplied resulted in the highest N deposition, and the ratio of N acquired from deposition to total N content of the whole system decreased with increasing N supply to the roots. The contribution of atmospheric N to the total N content of the wheat and ryegrass sand culture systems ranged from 10% to 24%. | Christie PETER Fangmeier ANDREAS | 2010 | Journal of Arid Land2010，2，1： | 5 |
| 2 | Cadmium pollution from phosphate fertilizers in arable soils and crops:an overview显示文摘The application of mineral and organic phosphorus fertilizers to arable land has greatly increased crop yield to meet the world food demand.On the other hand,impurities in these fertilizers,such as heavy metals,are being added to agricultural soils,resulting both from the raw materials themselves and the processes used to obtain the final product.Cadmium,a non-essential and toxic heavy metal,has been found in relatively high amounts in common P fertilizers obtained from sediments.This metal poses a high risk for soil fertility,crop cultivation,and plants in general.Furthermore,human health might be compromised by the cadmium concentrations in agricultural and livestock products,due to the bioaccumulation effect in the food web.The accumulation in the different matrixes is the result of the high mobility and flexible availability of this harmful metal.This review summarizes risks to human health,the factors influencing cadmium movement in soils and crop uptake,as well as common plant responses to its toxicity.In addition,it summarizes cadmium balances in soils,trends,long-term experiments,and further studies.Cadmium inputs and outputs in arable soil,together with their calculated concentrations,are compared between two different regions:the European countries(in particular Germany)and China.The comparison appears useful because of the different proportions in the inputs and outputs of cadmium,and the diverse geographical,environmental and social factors.Moreover,these variables and their influences on cadmium contamination improve the understanding of the pollution from phosphate fertilizers and will help to establish future mitigation policies. | Andrea Giovanna NINO-SAVALA Zhong ZHUANG Xin MA Andreas FANGMEIER Huafen LI Aohan TANG Xuejun LIU | 2019 | Frontiers of Agricultural Science and Engineering2019，6，4： | 2 |
