Short-term impacts of high levels of nitrogen fertilization on soil carbon dynamics in a tropical pasture
(2019-03-01)
Bermudagrass (Cynodon spp.) is widely recognized by its ability to respond positively to nitrogen (N) fertilization. Nitrogen often promotes shoot and root growth and, consequently, increase carbon (C) inputs into the soil ...

Leucaena leucocephala introduction into a tropical pasture in the Chaco region of Argentina. Effects on soil carbon and total nitrogen = Introducción de Leucaena leucocephala en una pastura tropical en el Chaco argentino. Efectos en el carbono y nitrógeno total del suelo
(CIAT, 2019)
The introduction of leucaena (Leucaena leucocephala), apart from increasing animal production, improves soil fertility through biological nitrogen (N) fixation and its deep-rooted system. There is limited information on ...
Nitrogen mineralization indicators under semi-arid and semi-humid conditions: influence on wheat yield and nitrogen uptake
(Taylor & Francis, 2018-06-18)
The objectives were i) to assess indicators for potential nitrogen (N) mineralization and ii) to analyze their relationships for predicting winter wheat (Triticum aestivum L.) growth parameters (yield and N uptake, Nup) ...

Isotopic studies in Pacific Panama mangrove estuaries reveal lack of effect of watershed deforestation on food webs
(Elsevier, 2015-02)
Stable isotopic N, C, and S in food webs of 8 mangrove estuaries on the Pacific coast of Panama were measured to 1) determine whether the degree of deforestation of tropical forests on the contributing watersheds was ...
The carbon and nitrogen budget of Desmophyllum dianthus-a voracious cold-water coral thriving in an acidified Patagonian fjord
(2021)
In the North Patagonian fjord region, the cold-water coral (CWC) Desmophyllum dianthus occurs in high densities, in spite of low pH and aragonite saturation. If and how these conditions affect the energy demand of the ...
Organic C, N and P in size fractions of virgin and cultivated soils of the semi-arid pampa of Argentina
(Academic Press Ltd - Elsevier Science Ltd, 2001-02)
Nutrient and organic carbon (OC) losses are important components of the soil degradation processes produced by continuous agriculture. It was hypothesized that coarse textured soils will be more affected by cultivation ...
Combined analysis of trace elements and isotopic composition of particulate organic matter in suspended sediment to assess their origin and flux in a tropical disturbed watershed
(Elsevier B.V., 2016-11-01)
Approximately 40% of the volume of domestic sewage generated in the Sao Paulo State is untreated and released into water bodies, causing serious pollution problems that affect the water quality and especially the suspended ...
Dinâmica do carbono em latossolo vermelho sob sistemas de preparo de solo e de culturas
(Universidade Federal de Santa MariaBRAgronomiaUFSMPrograma de Pós-Graduação em Ciência do Solo, 2006-04-27)
The soil C stock is a consequence of the balance between the C losses by the CO2 emission (associate to the heterotrofic microorganisms activity) and erosion, and to C inputs, associate to organic compounds input by the ...
