 Author(s): SANTOS, N. G. N. dos; OLSZEVSKI, N.; SALVIANO, A. M.; CUNHA, T. J. F.; GIONGO, V.; PEREIRA, J. S. Soils attributes such as granulometry and density determine the distribution of pore size and condition physical and differentiated hydraulic behavior. Thus, knowing the characteristics of the soils a... ... |
 Author(s): DICK, D. P.; LIMA, M. O.; COSTA, F. de S.; COSTA, J. B. da In the Amazon region, forest burning is still common in spite of the governmental control. Pyrogenic C produced by the fire, due to its aromatic structure, may represent a C pool of small turnover rat... ... |
 Author(s): CARVALHO, M. T. de M.; MAIA, A. de H. N.; MADARI, B. E.; BASTIAANS, L.; VAN OORT, P. A. J.; HEINEMANN, A. B.; SILVA, M. A. S. da; PETTER, F. A.; MARIMON JUNIOR, B. H.; MEINKE, H. Abstract: The main objective of this study was to assess the impact of biochar rate (0, 8, 16 and 32 Mg ha-1) on the water retention capacity (WRC) of a sandy loam Dystric Plinthosol. The applied bioc... ... |
 Author(s): FLUMIGNAN, D. L.; GOMES, L. D.; MOTOMIYA, A. V. A; OLIVEIRA, G. Q. de; VIEIRA FILHO, P. S. Sandy-textured soils are naturally more vulnerable to the erosion process and their exploitation, although possible, is often performed inappropriately, favoring its degradation.

 Author(s): FONTANA, A.; PEREIRA, M. G.; SANTOS, J. J. S. dos; DONAGEMMA, G. K.; SANTOS, O. A. Q. dos The specific adsorption of phosphorus in minerals from the clay fraction of the soil, such as Fe and Al oxyhydroxides, is responsible for the decrease in the availability of this element for plants. I... ... |
