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 ...
Efecto del suministro de gallinazo sobre el proceso de nitrificación en suelos agrícolas de los páramos de Mérida
(Proceedings del XVIII Congreso Venezolano de la Ciencia del Suelo. Ediciones en CD. 6 p., 2009)
El objetivo fue evaluar el efecto del gallinazo sobre el proceso de nitrificación en tres suelos agrícolas de los Páramos de Mérida, contrastantes en sus propiedades físicoquímicas e historias de manejo. Para ello se ...
