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 ...
Contribuition of nitrogen from biological nitrogen fixation, nitrogen fertilizer and soil nitrogen on the growth of the common bean and cowpea
(INST AGRONOMICO, 2011)
Biological nitrogen fixation (BNF) constitutes a valuable source of this nutrient for the common bean Phaseolus vulgaris L and cowpea Vigna unguiculata (L.) Walp., being its avaibility affected by mineral N in the soil ...
Water and nitrogen supply effects on four desert shrubs with potential use for rehabilitation activities
(Springer, 2018-07)
Desert evergreen shrubs, which are adapted to low-fertility ecosystems, generally exhibit limited responses to increased nutrient availability and tend to absorb and store nutrients rather than synthesize new tissues. The ...
Pattern of fecal endogenous nitrogen excretion in rats fed leguminous diets
(Center Acad Publ JapanTokyoJapão, 1996)
NON-SYMBIOTIC NITROGEN FIXATION, NET NITROGEN MINERALIZATION AND DENITRIFICATION IN EVERGREEN FORESTS OF CHILOÉ ISLAND, CHILE: A COMPARISON WITH OTHER TEMPERATE FORESTS
(Facultad de Ciencias Naturales y Oceanográficas, Universidad de Concepción, 2003)
Nitrogen mineralization in a coarse soil of the semi-arid Pampas of Argentina
(Taylor & Francis, 2012-01)
Use of the nitrogen balance sheet method as a fertilization strategy in the semiarid Pampas of Argentina is restricted because of a lack of available information regarding nitrogen mineralization in its coarse soils. Our ...
Application of different nitrogen doses to increase nitrogen efficiency in Mombasa guinegrass (Panicum maximum cv. mombasa) at dry and rainy seasons
(2017-12-01)
Nitrogen is the nutrient that most influences productivity and pasture quality but nitrogen fertilization efficiency still needs to be increased. The objective of this work was to study the efficiency of nitrogen sources ...
Atmospheric concentrations and dry deposition of reactive nitrogen in the state of São Paulo, Brazil
(2020-06-01)
Estimates of nitrogen deposition play a key role in better understanding the human impacts on the nitrogen biogeochemical cycle. This paper examines the concentration of reactive nitrogen (Nr) in the atmosphere and the ...
Sulfur affects root growth and improves nitrogen recovery and internal efficiency in wheat
(Taylor, 2017-05)
Wheat plants were cultivated in pots with the objective of evaluating the effect of two sulfur (S) rates (+S and −S) on (i) shoot growth, S and nitrogen (N) uptake and nitrogen use efficiency (NUE) and (ii) root growth and ...
