Microbial recycling of dissolved organic matter confines plant nitrogen uptake to inorganic forms in a semi-arid ecosystem
(Elsevier, 2016-10)
Plant uptake of dissolved organic nitrogen (DON) has been proposed to explain inconsistency in the ecosystem N balance of semi-arid systems. Nevertheless, direct evidence for an ecologically important role of DON in plant ...
Photo-Fenton approach for the determination of organic nitrogen in rainwater
(2018-10-01)
The importance of taking the organic forms of nitrogen (ON) into account when estimating atmospheric nitrogen deposition has been known for a long time. However, there is still only a modest amount of data on organic ...
Challenging the paradigm of nitrogen cycling: no evidence of in situ resource partitioning by coexisting plant species in grasslands of contrasting fertility
(Wiley, 2015-01)
In monoculture, certain plant species are able to preferentially utilize different nitrogen (N) forms, both inorganic and organic, including amino acids and peptides, thus forming fundamental niches based on the chemical ...
Effects of litter manipulation in a tropical Eucalyptus plantation on leaching of mineral nutrients, dissolved organic nitrogen and dissolved organic carbon
(Elsevier B.V., 2014-11-01)
Although many studies have shown that soil solution chemistry can be a reliable indicator of biogeochemical cycling in forest ecosystems, the effects of litter manipulations on the fluxes of dissolved elements in gravitational ...
Effect of cover crops on leaching of dissolved organic nitrogen and carbon in a maize-cover crop rotation in Mediterranean Central Chile
(Elsevier B.V., 2019)
© 2018 Elsevier B.V. Protection and management of water quality across agricultural landscapes requires a sound understanding of runoff and/or leaching of nutrients and other agrichemicals from agricultural production ...
Dissolved Organic Carbon and Nitrogen in Andisol for Six Crop Rotations with Different Soil Management Intensity
(Instituto de Investigaciones Agropecuarias, INIA, 2009)
Inibição da mineralização de compostos nitrogenados de lixiviado de macrófita aquática: Adequação metodológica
(2008-04-01)
This study aimed to establish the adequate concentrations of nitrapyrin for the effective inhibition of oxygen demand required for the oxidation of nitrogen compounds during aerobic mineralization of leachate. The aquatic ...
