18/03/2010· Ammonia released this way is in turn re-assimilated by GS1 to produce glutamine for export. The importance of GS1 in nitrogen management, growth rate, yield and grain filling has been emphasized by functional genomics and quantitative trait loci (QTL) approaches mainly performed on rice and maize (Hirel et al., 2001; Obara et al., 2004; for a ...

19/05/2015· Nitrogen export increased in wet years but decreased in dry years, indicating that water availability is a limiting factor for nitrogen export and that precipitation largely controls water fluxes for delivering nitrogen from land to rivers [Goolsby et al., 2000]. Land cover change is another factor that influenced long-term trends in nitrogen ...

31-01-2015· Combining nitrogen-management practices with nitrogen-removal practices can dramatically reduce nutrient export from agricultural landscapes while minimizing impacts to agricultural production. With this approach, it may be possible to meet the 45% nutrient reduction goal while converting less than 1% of cropland in the UMORB to nitrogen-removal practices.
Chat Online11-10-2021· Nutrient export to lakes from rivers is the main cause of eutrophication problems. Seasonal trends in nitrogen (N) export by rivers to lakes are still not well understood. The objective of this study is, therefore, to better understand the seasonal trends in river export of dissolved inorganic N (DIN) to lakes of the Hai He Basin.

31-12-2001· Most models predicted stream nitrogen export to within 50% of the measured export in a majority of the watersheds. Prediction errors were negatively correlated with cultivated land area, indicating that the watershed models tended to over predict export in less agricultural and more forested watersheds and under predict in more agricultural basins.
