Adubos nitrogenados aplicados em capim - Coastcross: recuperação aparente do nitrogênio.
(In: REUNIÃO ANUAL DA SOCIEDADE BRASILEIRA DE ZOOTECNIA, 39., 2002, Recife, PE. Anais... Recife: SBZ: Ed. dos Editores, 2002. 4f. 1 CD-ROM., 2011)
AMMONIUM AND NITRATE IN SOIL AND RATOON SUGARCANE GROWN IN FUNCTION OF NITROGEN ON OXISOL
After harvest, sugarcane residues left on the soil surface can alter nitrogen (N) dynamics in the plant-soil system. In Oxisols, the nitrogen fertilizer applied had its effects on the levels of ammonium and nitrate in the ...
Regional model for nitrogen fertilization of site-specific rainfed corn in haplustolls of the central Pampas, Argentina
In semi-arid regions, soil water and nitrogen (N) are generally limiting factors for corn (Zea mays L.) production; hence, implementation of appropriate N fertilization strategies is needed. The use of precision agriculture ...
Produção de tapetes de grama Santo Agostinho submetida a doses de nitrogênio

Nitrogen utilization efficiency in maize as affected by hybrid and N rate in late-sown crops
(Elsevier Science, 2014-11)
After the introduction of Bt-maize, late sowing is becoming an important strategy to stabilize yields in many areas of the Argentine Pampas. Increased nitrogen (N) availability and sharp reduction in radiation and temperature ...
Morphogenetic and tillering dynamics in Tanzania grass fertilized and non-fertilized with nitrogen according to season

Adubação nitrogenada em milho em semeadura direta e cultivo convencional na região Meio-Norte do Piauí
(Universidade Estadual Paulista (UNESP), 2010-07-13)
O nitrogênio é nutriente absorvido em maiores quantidades na cultura do milho e o que proporciona maiores produtividades de grãos, sendo seu uso no sistema solo-planta alterado pelo sistema de cultivo utilizado. Com o ...
The relationship between leaf nitrogen, nitrogen metabolites and herbivory in two species of Nyctaginaceae from the Brazilian Cerrado
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)
Guapira graciliflora and Neea theifera are taxonomically related species of the tribe Pisoneae. Both species are found in the same environment, the Brazilian Cerrado, and therefore, are subjected to similar selective ...
Partitioning of net primary production in Eucalyptus and Acacia stands and in mixed-species plantations: Two case-studies in contrasting tropical environments
The introduction of nitrogen fixing species (NFS) in fast-growing tree plantations is an alternative option to reduce fertilizer inputs. However, the success of mixed-species plantations depends on the balance between ...
Nitrogen diffusion in the Nb-1.0wt%Zr measured by mechanical spectroscopy
(Trans Tech Publications Ltd, 2008-01-01)
The scientific and technological development in the area of new materials contributed to several applications of niobium and its alloys in nuclear power plants as well as in aerospace, aeronautics, automobile and naval ...
