Identifying soil horizons transitions for ground-truthing and interpreting ground penetrating radar (GPR) imagery of Planosols. Authorship: NASCIMENTO, C. W. R. do; CEDDIA, M. B.; VASQUES, G. M.; RODRIGUES, H. M.; MARTINS, S. S.; OLIVEIRA, R. P. de; TAVARES, S. R. de L. The Ground Penetrating Radar (GPR) has potential to characterize soils both vertically and horizontally. The effectiveness of using GPR relies on the interpretation of soil targets in the radargrams.... ... Repository: BDPA Publication year: 2023
Proximal and remote sensor data fusion for in-depth salinization mapping in the Brazilian semiarid via machine learning. Authorship: TAVARES, S. R. de L.; VASQUES, G. de M.; OLIVEIRA, R. P. de; DANTAS, M. M.; RODRIGUES, H. M. Mapping the salinization in irrigated cropland is a challenging practice. As an alternative, data from proximal and remote sensors have been implemented together via datafusion and machine learning al... ... Repository: BDPA Publication year: 2022
Estudo de caso 1 - técnicas de agricultura de precisão para criação de zonas de manejo usando sensores proximais e software R na Fazenda Pamplona, Cristalina, GO. Authorship: OLIVEIRA, R. P. de; BRANDAO, Z. N.; RODRIGUES, H. M. O objetivo geral deste trabalho foi avaliar três técnicas de delineamento de ZMs, tendo como foco a melhoria da produtividade do algodoeiro em um sistema de produção comercial. As três técnicas de obt... ... Repository: BDPA Publication year: 2022
An optimized sample for assessing soil property variations across the field and within management zones efficiently. Authorship: VASQUES, G. de M.; RODRIGUES, H. M.; TAVARES, S. R. de L.; HERNANI, L. C.; OLIVEIRA, R. P. de An optimized sampling design to assess soil property variation across the field and within management zones is proposed and validated in a 72-ha crop field in southeastern Brazil. An optimized sample... ... Repository: BDPA Publication year: 2022
Iron rods in support of the use of ground penetrating radar with 450 MHz monostatic antenna for imaging argillic horizon. Authorship: NASCIMENTO, C.; VASQUES, G. de M.; RODRIGUES, H. M.; CEDDIA, M. This work aimed to use a GPR equipped with a 450 MHz antenna to identify the depth of the clayey horizon marked with iron rods in Planosols. This study was carried out in an agroecological farm (Fazen... ... Repository: BDPA Publication year: 2022
Management zones from proximal soil sensors capture within-field soil property and terrain variations. Authorship: VASQUES, G. de M.; RODRIGUES, H. M.; OLIVEIRA, R. P. de; HERNANI, L. C.; TAVARES, S. R. de L. The objectives are to delineate soil management zones from soil proximal sensor data, and compare soil property values among zones in a 72-ha crop field in southeastern Brazil. Apparent electrical con... ... Repository: BDPA Publication year: 2022
Ground penetrating radar non-invasively positions an underground dam and estimates its water reservoir shape and volume. Authorship: VASQUES, G. de M.; RODRIGUES, H. M.; HUBER, E.; TAVARES, S. R. de L.; MARQUES, F. A.; SILVA, M. S. L. da The objectives are to use ground penetrating radar (GPR) to: (a) find a suitable length and location for a future underground dam; and (b) model the shape and estimate the volume of its water reservoi... ...
