dc.descriptionABSTRACT - The quantification of water used by soybean crop in the Brazilian Savanna and its relationships of micrometeorological factors are important dates for use water models for this agroecosystem. The aim was to determine the energy balance components in unrainy days in the wet season of a soybean crop (Glycine max cv Celeste) located in the rural region PAD, DF, Brazil. An automated micrometeorological station and an eddy covariance system were used to determine the principal flux densities of the energy balance components: Rn, net radiation; LE, latent heat; H, sensible heat and G, soil heat. The values of the densities of the energy balance fluxes were analyzed for two unrainy days: 19/12/2001 (49 days after plantation) and 09/01/2001 (70 days after plantation). Rn was portioned at 19/12/2001 in 23% (H), 53% (LE), 24% (G) and at 09/01/2002, 22% (H), 69% (LE), 9% (G). The Bowen ratio decreased of 0.45 to 0.32. The daily evapotranspiration were of 2.7 mm in 19/12/2001 and 4.1 mm in 09/01/2002.
