Spatial influence of physical and chemical parameters on management zone definition in apple orchards. Author(s): GEBLER, L.; GREGO, C. R.; VIEIRA, A. L.; KUSE, L. da R. Precision agriculture adoption in Brazilian apple orchards is still incipient. This study aimed at evaluating the spatial variability of certain soil properties as soil density, soil penetration resis... ... Repository: BDPA Publication year: 2015
Application of calcium nitrate and urea by frtirrigation on banana crop and their efects on soil ph and electrical conductivity. Author(s): ALVES, M. da S.; COELHO, E. F.; ANDRADE NETO, T. M. de; SANTANA, J. A. do V.; SANTANA JUNIOR, E. B. Fertirrigation is one effective mean of fertilizer application in irrigated agriculture since it combines water and nutrients, two necessary inputs for growth and production of crops. The objective of... ... Repository: BDPA Publication year: 2008
Delineation of irrigation management zones in a Quartzipsamment of the brazilian Semiarid region. Author(s): OLDONI, H.; BASSOI, L. H. The objective of this work was to delineate irrigation management zones using geostatistics and multivariate analysis in different combinations of physical and hydraulic soil properties, as well as to... ...

Do scarification and seed soaking periods promote maximum vigor in seedlings of Hymenaea courbaril? Author(s): SMIDERLE, O. J.; SOUZA, A. G. Objetivou-se estabelecer metodologia para determinar vigor fisiológico em sementes pequenas e grandes de Hymenaea courbaril L. não escarificadas e escarificadas pelo teste de condutividade elétrica e... ... Repository: BDPA Publication year: 2021
Teste de condutividade elétrica para sementes de pinhão-manso (Jatropha curcas L.). Author(s): ARAUJO, R. F.; ZONTA, J. B.; ARAUJO, E. F.; DONZELES, S. M. L.; COSTA, G. M. Para uma análise mais completa da qualidade de sementes, faz-se necessário complementar as informações fornecidas pelo teste de germinação com testes de vigor, possibilitando, assim, selecionar os mel... ...

Management zones from proximal soil sensors capture within-field soil property and terrain variations. Author(s): 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
Rapid and versatile biosensing of liposome encapsulation efficiency using electrical conductivity sensor. Author(s): PEREIRA, T. M.; BONATTO, C. C.; SILVA, L. P. da Repository: BDPA Publication year: 2023
Concentração da solução de injeção e frequência de fertirrigação em latossolo amarelo. Author(s): TEIXEIRA, J. de C.; COELHO, E. F.; BARROS, D. L. A concentração da solução de injeção tem sido pouco considerada na fertirrigação. Entretanto ela pode influenciar o estado salino do solo, com risco de aumentos instantâneos da salinidade, que pode co... ... Repository: BDPA Publication year: 2014
Spatial variability of vegetation index and soil properties in an integrated crop-livestock system. 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... ... Repository: BDPA Publication year: 2017
Soil salinity under three calcium nitrate concentrations of irrigation water for two trickle irrigation systems. 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... ... Repository: BDPA Publication year: 2008
