Other benefits of the practice. 5. Potential drawbacks to the practice. 6. Recommendations before... ... Repository: BDPA Publication year: 2021
Studies of the compositions of humic acids from Amazonian Dark Earth soils. Author(s): NOVOTNY, E. H.; AZEVEDO, E. R. de; BONAGAMBA, T. J.; CUNHA, T. J. F.; MADARI, B. E.; BENITES, V. de M.; HAYES, M. H. B. The compositions of humic acids (HAs) isolated from cultivated and forested "Terra Preta de Índio" or Amazonian Dark Earth soils (anthropogenic soils) were compared with those from adjacent non-anthro... ... Repository: BDPA Publication year: 2007
Initial root length in wheat is highly correlated with acid soil tolerance in the field. Author(s): PEREIRA, J. F. ABSTRACT: In acid soils, toxic aluminum ions inhibit plant root growth. In order to discriminate aluminum (Al) tolerance, trustful screening techniques are required. In this study, 20 wheat cultivars,... ... Repository: BDPA Publication year: 2018
Peach rootstock tolerance to excess zinc in sandy acidic soil. Author(s): BRUNETTO, G.; TIECHER, T. L.; HAMMERSCHMITT, R. K.; BASSO FACO, D.; FERREIRA, P. A. A.; DECONTI, L.; OLIVEIRA, S. da S. L.; MAYER, N. A.; ANTUNES, L. E. C.; CESSO, S.; MIMMO, T. Repository: BDPA Publication year: 2017
Project - Selection of bean cultivar (Phaseolus vulgaris L.) to soil acidity tolerance. Author(s): OLIVEIRA, I. P. de; MOREIRA, F. P.; RODRIGUES, C.; DEL PELOSO, M. J. Repository: BDPA Publication year: 2005
Plant phosphorus use efficiency in acid tropical soil. Author(s): VASCONCELOS, M. J. V. de; FIGUEIREDO, J. E. F.; OLIVEIRA, M. F. de; SCHAFFERT, R. E.; RAGHOTHAMA, K. G. ABSTRACT - Phosphorus is an essential macronutrient for plant growth and development. However, phosphorus availability is low in many soils, and the plant?s ability to acquire phosphorus from the rhiz... ... Repository: BDPA Publication year: 2022
Spatial variability of soil acidity attributes and the spatialization of liming requirement for corn. Author(s): HURTADO, S. M. C.; SILVA, C. A.; RESENDE, A. V. de; PINHO, R. G. von; INÁCIO, E. dos S. B.; HIGASHIKAWA, F. S. In Brazil, technicians, in most cases, ignore the aspects related to the spatial variability of the soil acidity attributes when liming requirement is calculated. The objective of this study was to va... ... Repository: BDPA Publication year: 2009
Emerging pleiotropic mechanisms underlying aluminum resistance and phosphorus acquisition on acidic soils. Author(s): MAGALHAES, J. V. de; PIÑEROS, M. A.; MACIEL, L. S.; KOCHIAN, L. V. Aluminum (Al) toxicity on acidic soils significantly damages plant roots and inhibits root growth. Hence, crops intoxicated by Al become more sensitive to drought stress and mineral nutrient deficienc... ... Repository: BDPA Publication year: 2018
Influence of urea and ammonium sulfate on soil acidity indices in lowland rice production. Author(s): FAGERIA, N. K.; SANTOS, A. B. dos; MORAES, M. F. Urea and ammonium sulfate are principal nitrogen (N) sources for crop production. Two field experiments were conducted during three consecutive years to evaluate influence of urea and ammonium sulfate... ... Repository: BDPA Publication year: 2010
Humic Acids of the Amazonian Dark Earth Soils: Terra Preta De Índio. Author(s): CUNHA, T. J. F.; MADARI, B. E.; MARTIN NETO, L.; CANELLAS, L. P.; SIMOES, M. L.; SILVA, W. T. L. da; MILORI, D. M. B. P.; RIBEIRO, L. P.; ANJOS, L. H. C.; SANTOS, G. de A. The humic acid fraction (HA) of some Amazonian dark earth soils (Terra Preta de Índio) from Brazil were characterized using ultraviolet-visible (UV-Vis), Fourier transform diffuse reflectance infrared... ...
