Última Calibration of a soil moisture sensor with disturbed and undisturbed soil samples from Bahia AGRIAMBI Lima,João G. A.; Oliveira,Aureo S. de; Souza,Luciano da S.; Silva,Neilon D. da; Viana,Paula C.. ABSTRACT The objective of this study was to evaluate the models proposed by manufacturers and in the literature with respect to soil moisture measurement and to evaluate the performance of the CS616 sensor in the calibration of disturbed and undisturbed soil samples. These calibrations were performed using linear and quadratic models. Disturbed samples were collected in São Gabriel/BA, six samples placed in pots, whereas undisturbed samples were collected in Cruz das Almas/BA, three samples directly collected in the area and placed in a container. A calibration was performed between 21/12/2016 and 08/01/2017. The models proposed in the literature and by manufacturers differed in the estimation of volumetric soil moisture. Disturbed soil samples had higher... Tipo: Info:eu-repo/semantics/article Palavras-chave: Soil water content; Time domain reflectometry; Soil physics.

A.; Sánchez,Juan M.; Piqueras,José G.; Espínola Sobrinho,José; Viana,Paula C.; Alves,Aline da S.. ABSTRACT The estimate of the actual surface evapotranspiration (ET) contributes to quantifying the water needs of crops. An alternative to the use of lysimeter for an accurate estimation of water needs, which has proved to be of great value in recent years, is the use of remote sensing combined with models based on surface energy balance. There is wide variety of models that can be classified into two types: one-source models, such as the Mapping EvapoTranspiration at high Resolution with Internalized Calibration (METRIC) algorithm, or two-source models, such as the Simplified Two-Source Energy Balance (STSEB). The objective of this study was to analyze how METRIC and STSEB can be used to estimate ET, in comparison with the lysimeter data, for the...
