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 ...
Modeling organic transformations by microorganisms of soils in six contrasting ecosystems: Validation of the MOMOS model
(Global Biogeochemical Cycles 24, GB1008,doi:10.1029/2009GB003527, 2010-02-26)
The Modeling Organic Transformations by Microorganisms of Soils (MOMOS) model simulates the growth, respiration, and mortality of soil microorganisms as main
drivers of the mineralization and humification processes of ...
Modelling the transformations and sequestration of soil organic matter in two contrasting ecosystems of the Andes
(European Journal of Soil Science 58(3): 775-785, 2007-06)
The mechanisms linking soil respiration to climate and soil physical properties are important for modelling transformation and sequestration of C and N in the soil. We investigated them by incubating 14C and 15N labelled ...
Destino del nitrógeno agregado por fertilización en un cultivo de papa en Los Andes de Venezuela
(Revista de la Facultad de Agronomía de Luz 24(2): 203-228, 2007)
Se analizó el destino del N agregado por fertilización mineral en una parcela
de papa cultivada con 288 kg ha-1 de N marcado (15N) en los páramos venezolanos
y se comparó con el balance de N de una parcela sin fertilizar. ...
Factors controlling decomposition of soil organic matter in fallow systems of the high tropical Andes: A field simulation approach using 14C- and 15N- labelled plant material
(2006)
N-rich (C:N ¼ 27) and N-poor (C:N ¼ 130) wheat straw, labelled with 14C and 15N, was incubated for 2 yr in two major ecosystems of the upper elevation belt of cultivation in the high Andes: the moist Paramo (precipitation ...
Decomposition of standard plant material along an altitudinal transect (65-3968 m) in the tropical Andes
(2002)
The dynamics of plant decomposition in the soil were analysed in an altitudinal transect from 65 to 3968 m under tropical conditions. Six sites were studied, with a mean annual temperature ranging from 5.5 to 27.4°C, and ...
