Pedotransfer functions to estimate water retention parameters of soils in notheastern Brazil. Author(s): BARROS, A. H. C.; LIER, Q. de J. van; MAIA, A. de H. N.; SCARPARE, F. V. Pedotransfer functions (PTF) were developed to estimate the parameters (a, n, qr and qs) of the van Genuchten model (1980) to describe soil water retention curves. The data came from various sources,... ... Repository: BDPA Publication year: 2013
Nitrate concentration in the soil solution as affected by irrigation water concentration in fertirrigation. Author(s): ANDRADE NETO, T. M. de; COELHO, E. F.; SANTANA, J. A. do V.; SANTANA JUNIOR, E. B.; ALVES, M. da S. The use of fertirrigation provides larger fertilizer application efficiency, reduction on labor and increases in the benefit-cost relationship to farmers. The inadequate use of fertilizer in fertirrig... ... Repository: BDPA Publication year: 2008
Soybean development under soil water deficit. Author(s): SIMEÃO, M.; ANDRADE JUNIOR, A. S. de; SILVA, E. M. da; RIBEIRO, A. de A.; BASTOS, E. A. One of the main factors affecting soybean development is water deficiency, especially when it occurs during the flowering and pods filling stages. Thus, this study aimed to evaluate the soybean develo... ... Repository: BDPA Publication year: 2018
Effects of glyphosate-resistant crop cultivation on soil and water quality. Author(s): CERDEIRA, A. L.; DUKE, S. O. Transgenic glyphosate-resistant crops (GRCs) have been com- mercialized and grown extensively in the western Hemisphere and, to a lesser extent, elsewhere. GRCs have generally become dominant in those... ... Repository: BDPA Publication year: 2010
Analyzing ecological restoration strategies for water and soil conservation. Author(s): SAAD, S. I.; SILVA, J. M. da; SILVA, M. L. N.; GUIMARAES, J. L. B.; SOUSA JUNIOR, W. C.; FIGUEIREDO, R. de O.; ROCHA, H. R. da Abstract: The choice of areas for nature conservation involves the attempt to maximize the benefits, whether by carrying out an economic activity or by the provision of Ecosystem Services. Studies are... ... Repository: BDPA Publication year: 2018
How to predict soil water holding capacity using physically based equations? Author(s): TEIXEIRA, W. The soil surface and porosity govern the capacity of soil to hold water. In soil science, many functions were developed to estimate parameters of equations to describe soil water retention and soil hy... ... Repository: BDPA Publication year: 2014
Soil and water: sources of life in an enchanted kingdom. Author(s): CAPECHE, C. L.; OLIVEIRA, J. G. R. de; RIBEIRO, L. de O.; PAGLIACCI, M. P.; MELLO, A. A. C. de Repository: BDPA Publication year: 2024
Carbon and water in upper montane soils and their influences on vegetation in Southern Brazil. Author(s): SCHEER, M. B.; CURCIO, G. R.; RODERJAN, C. V. Considering the many environmental functions of the upper montane soils, the aims of this study were (1) to verify if the soils of uppermontane forests and grasslands of Caratuva Peak (1850ma.s.l.) ha... ...

Evapotranspiration of mango crop by water soil balance under a microsprinkler irrigation system. Author(s): COTRIM, C. E.; COELHO, E. F.; COELHO FILHO, M. A.; RAMOS, M. M. The evapotranspiration of the mango crop was estimated by the soil water balance method in a ten-year age microsprinkler irrigated mango orchard. The experiment was carried out at Federal Agricultural... ... Repository: BDPA Publication year: 2008
Evapotranspiration of mango crop by water soil balance under a drip irrigation system. Author(s): COTRIM, C. E.; COELHO, E. F.; COELHO FILHO, M. A.; RAMOS, M. M. The evapotranspiration of the mango crop was estimated by the soil water balance method in a drip irrigated mango orchard implanted in 1998. The experiment was carried out at Federal Agricultural Tech... ... Repository: BDPA Publication year: 2008
