Estimating electrical conductivity and sodium concentration in soil solution under diferent soil salinity conditions in lysimeters. Authorship: COELHO, E. F.; SANTANA, J. A. do V.; VEIMROBER JUNIOR, L. A. dos A.; SANTANA JUNIOR, E. B. TDR technique has been used as a tool or monitoring soil electrical conductivity and ion concentration n the soil. The objective of this study was to valuate models for estimating soil solution sodium... ... Repository: BDPA Publication year: 2008
Application of calcium nitrate and urea by frtirrigation on banana crop and their efects on soil ph and electrical conductivity. Authorship: 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
Mapping of yield, economic return, soil electrical conductivity, and management zones of irrigated corn for silage. Authorship: BERNARDI, A. C. de C.; TUPY, O.; SANTOS, K. E. L.; MAZZUCO, G. G.; BETTIOL, G. M.; RABELLO, L. M.; INAMASU, R. Y. O objetivo deste trabalho foi avaliar a variabilidade espacial e temporal do rendimento de milho irrigado para silagem, bem como seu retorno econômico. O estudo foi conduzido em área de 18.9 ha de pro... ... Repository: BDPA Publication year: 2018
Implementation of a controller unit based on the ISO 11783 standard for automatic measurement of the electrical conductivity of the soil. Authorship: SOUSA, R. V.; PEREIRA, R. R. D.; LOPES, W. C.; RABELLO, L. M.; INAMASU, R. Y. Repository: BDPA Publication year: 2012
Soil salinity under three calcium nitrate concentrations of irrigation water for two trickle irrigation systems. Authorship: 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
Spatial variability of vegetation index and soil properties in an integrated crop-livestock system. Authorship: 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
