nitrogen fertilizer

N2O emissions resulting from the application of nitrogen (N) fertilizers and vinasse represent the main sources of greenhouse gases (GHG) emissions in sugar-energy sector. Conversely, the application of biochar in soils has been worldwide recognized as an strategy to mitigate N2O emissions, although little is known about their effects on soils under energy cane production. […]

AbstractAmmonia-oxidizing archaea and bacteria (AOA and AOB, respectively) are important intermediate links in the nitrogen cycle. Apart from the AOA and AOB communities in soil, we further investigated co-occurrence patterns and microbial assembly processes subjected to inorganic and organic fertilizer treatments for over 35 years. The amoA copy numbers and AOA and AOB communities were found […]

In the modern world, food means fertilizer. Everything from a bowl of breakfast cereal to a curry relies on abundant use of synthetic fertilizer to raise crops or livestock. (The one notable exception, seafood, has its own carbon and sustainability problems). Over the last century, fertilizer use has enabled an unprecedented increase in human population […]

The proposal would jump-start several hydrogen projects in North Dakota and Minnesota, including Xcel using renewable power to make hydrogen for a potential fertilizer plant in Morris. The allure of “clean” hydrogen as a climate change remedy is so potent that Congress ponied up $8 billion for it. Xcel Energy and the state of Minnesota […]

Abstract The impacts of biochar addition with nitrogen fertilizer (Urea-N) on greenhouse gas (GHG) fluxes and grain yields are not comprehensively understood. Therefore, we designed a field experiment in an intensive rice–wheat cropping system located in the Taihu Lake region of China and measured CH4 and N2O emissions for 2 consecutive years to examine the impacts […]
