Human activities changing the nitrogen cycle in Brazil,ilizer application and atmospheric deposition are the main sources of anthropogenic nitrogen. In Brazil, the production of soybean crops over an area of less than 20 million ha, was responsible for about 3.2 Tg N or close to one-third of the N inputs from anthropogenic sources in 2002.

Nitrogen and phosphorus budgets for a tropical watershed impacted by agricultural land use: Guayas,sents net inputs of N and P to each watershed region. Overall, synthetic fertilizers are the largest input to the Guayas Basin for N (53%) and P (57%), and the largest outputs are N and P in crops. Losses of N and P in river export account for 14–38% of total N and P inputs, and there is significant作者: Melanocytes 時(shí)間: 2025-3-23 12:17
The influence of climate on average nitrogen export from large watersheds in the Northeastern Uniteon riverine nitrogen fluxes. Those watersheds that have higher precipitation and higher discharge export a greater fraction of the net anthropogenic inputs of nitrogen. This fractional export ranges from 10 to 15% of the nitrogen inputs in drier watersheds in the northeastern United States to over 3作者: 胰島素 時(shí)間: 2025-3-23 15:04 作者: 駭人 時(shí)間: 2025-3-23 22:03

The stable carbon and nitrogen isotopic composition of vegetation in tropical forests of the Amazonpitation was similar among the studied sites. Leaf δ.N values ranged from+0.9‰ to a maximum value of+10.9‰, and the Santarém sites showed more enriched values than Manaus and Ji-Paraná sites.
