Resumo

Soil moisture measurements, determined by oven-drying at 105°C and taken over a four month period (January thru May on 1979), were used to test the effects of various relationships between the Soil Moisture Coefficients (KB, KJ and KE, proposed, respectively, by BERNARDO, JENSEN et alii and EAGLEMAN) and the ratio of actual evapotranspiration (ER) to Class A pan evaporation (EV) on soil moisture estimate obtained by soil water balance approach.
