 Portable Soil EC - Development of an electronic device for determining soil electrical conductivity. Author(s): RAUBER, L. A.; BAZZI, C. L.; GEBLER, L.; RABELLO, L. M.; OLIVEIRA, W. K. M.; SOBJAK, R.; SCHENATTO, K. Decision-making in agriculture demands continuous monitoring, a factor that propels the advancement of tools within Agriculture 4.0. In this context, understanding soil characteristics is essential. E... ... |
 Author(s): BERNARDI, A. C. de C.; GREGO, C. R.; ANDRADE, R. G.; RABELLO, L. M.; INAMASU, R. Y. ABSTRACT - The knowledge of soil property spatial variability is useful for determining the rational use of inputs, such as the site-specific application of lime and fertilizer. The objective of this... ... |
 Author(s): ANDRADE NETO, T. M. de; COELHO, E. F.; SANTANA, J. A. do V.; SANTANA JÚNIOR, E. B.; ALVES, M. da S. Fertilizers are salts that may increase irrigation water salinity, therefore, fertirrigation management should consider aspects like the injection solution. The electrical conductivity of soil solutio... ... |
 Author(s): SILVA FILHO, A. M.; SILVA, C. L. B.; OLIVEIRA, M. A. A.; PIRES, T. G.; ALVES, A. J.; CALIXTO, W. P.; NARCISO, M. G. This paper presents the study of the relationship between electrical properties and physical characteristics of the soil. Measures of apparent electrical resistivity of the soil were made for differen... ... |
