Modeling microbial exchanges between forms of soil nitrogen in contrasting ecosystems
(Biogeosciences Discussions, 10(3): 5749-5780, 2013-03-25)
Although nitrogen (N) is often linked to carbon (C) in organic molecules, C is carried from the tmosphere to the soil through plants while N is carried from the soil to plants by microbial transformations. Many schemes ...

The use of organic substrates with contrasting C/N ratio in the regulation of nitrogen use efficiency and lossesin a potato agroecosystem
(Nutrient Cycl Agroecosystems 88(3): 411–427, 2010-12-01)
The effect of the application of organic
amendments of contrasting C/N ratio, combined with mineral N fertilizer, on the N budget of a potato crop was evaluated. The hypothesis was that the combination of substrates of ...
