8. Hourly, Daily, and Monthly Soil Temperature Fluctuations in a Drought Tolerant Crop
ABSTRACT Soil temperature is a physical property of great agricultural importance in the soil-plant relationship and in energy exchange with the atmosphere. This study was conducted in a degraded Cambissolo Háplico Ta Eutrófíco (Cambisol; Inceptisol) in the Irecê Identity Territory, Bahia, Brazil, aiming to evaluate the hourly, daily, and monthly fluctua

10. EVAPOTRANSPIRAÇÃO DA MELANCIA IRRIGADA POR MEIO DO SEBAL, BALANÇO HÍDRICO E CORRELAÇÕES TURBULENTAS / ESTIMATING IRRIGATED WATERMELON EVAPOTRANSPIRATION USING SEBAL, SOIL-WATER BALANCE AND EDDY CORRELATIONS
In applications of the SEBAL (Surface Energy Balance Algorithm for Land) algorithm parameters for physical processes adjusted for other regions of the planet are commonly used. Therefore, there is a need for validation of the estimates made with the algorithm compared with other conventional methods of estimating evapotranspiration. Thus, this study main goa

12. Development of an eletronic multi-sensor for measuring the humidity, temperature and electric conductivity of the soil / Desenvolvimento de um multi-sensor eletronico para medida da umidade, temperatura e condutividade eletrica do solo
The implementation of precision agriculture techniques requires the use of sensors which can measure the characteristics of the soil. In this work it was designed and fabricated a multi-sensor probe, capable of measuring the electrical conductivity, the volumetric humidity, and the temperature of the soil, using a four probes device. The electrical conductiv
