Resumo: | Monitoring of soil moisture is a key component in irrigation management and can be carried out with the aid of low-cost electromagnetic sensors. This study aimed to develop calibration equations for the HFM2030 sensor at different depths (0-20; 20-40; 40-60; 60-80; 100 cm) of Oxisols and to assess the accuracy levels of calibration equations used in the continuous monitoring of soil moisture. Reference values of soil moisture content were measured by a standard gravimetric method, converted to volumetric moisture, and then compared with sensor readings to develop calibration equations. The fit of the regression function was evaluated based on the determination coefficient (R2). The results indicated that the calibration equations were linear at different soil depths. Calibrating the HFM2030 sensor improved the estimate of volumetric water content by 31.21%, 23.46%, 24.93%, 31.93%, and 41.18% in the 0-20, 20-40, 40-60, 60-80 and 80-100 cm layers, respectively. Here, it is demonstrated that the correct calibration of HFM2030 should precede the installation and use of these sensors in the field. The results of this study represent another step toward the development of criteria aiming for greater precision in the use of sensors in irrigation management. The calibration equations developed in this study can be applicable and useful for farmers and researchers working with HFM2030 sensors in similar soil conditions in other regions of Brazil and globally. |

Este estudio tuvo como objetivo desarrollar ecuaciones de calibración para el sensor HFM2030 a diferentes profundidades (0-20; 20-40; 40-60; 60-80; 100 cm) de Oxisoles y evaluar los niveles de precisión de las ecuaciones de calibración utilizadas en el monitoreo continuo. de la humedad del suelo. Los valores de referencia del contenido de humedad del suelo se midieron mediante un método gravimétrico estándar, se convirtieron en humedad volumétrica y luego se compararon con las lecturas del sensor para desarrollar ecuaciones de calibración. El ajuste de la función de regresión se evaluó con base en el coeficiente de determinación (R2). Los resultados indicaron que las ecuaciones de calibración eran lineales a diferentes profundidades del suelo. La calibración del sensor HFM2030 mejoró la estimación del contenido volumétrico de agua en 31,21%, 23,46%, 24,93%, 31,93% y 41,18% en las capas de 0-20, 20-40, 40-60, 60-80 y 80-100 cm, respectivamente. Aquí, se demuestra que la correcta calibración del HFM2030 debe preceder a la instalación y uso de estos sensores en el campo. Los resultados de este estudio representan un paso más hacia el desarrollo de criterios que apuntan a una mayor precisión en el uso de sensores en la gestión del riego. Las ecuaciones de calibración desarrolladas en este estudio pueden ser aplicables y útiles para agricultores e investigadores que trabajan con sensores HFM2030 en condiciones de suelo similares en otras regiones de Brasil y a nivel mundial.O monitoramento da umidade do solo é um componente fundamental no manejo da irrigação e pode ser realizado com o auxílio de sensores eletromagnéticos de baixo custo.
