Resumos apresentados. Santo Antônio de Goiás: Embrapa Arroz e Feijãoc2011  aP. 45.  a(Embrapa Arroz e Feijão. Documentos, 270).  aThe increase in nitrogen prices and demand for sustainable production gave importance to studies on strategies that increase nitrogen use efficiency. Two experiments were conducted aiming to test the effect of Eucalyptus sp charcoal on nitrous oxide (N2O) emissions and N use efficiency.  aCarvão vegetal  aCerrado  aNitrogênio  aSolo1 aGONÇALVES, L.
