 Author(s): FERREIRA, E. J. B.; BROCCHI, E. A.; MAURICIO, G. M.; NUNES, R. A.; BENITES, V. de M. The aim of this work is to study the suitability of using different charcoals in order to produce humic-like acid. Fluorescence and UV-visible spectroscopy were applied to evaluate the humidification... ... |
 Author(s): AGUIAR, N. O.; CANELLAS, L. P.; OLIVARES, F. L.; BUSATO, J. G.; SILVA, L. G. JR. S.; NOVOTNY, E. H.; FAÇANHA, A. R. The aim of this work was to evaluate chemical changes and plant growth-promoting effect of HA from different maturing stages isolated from vermicompost, relating bioactivity and its chemical character... ... |
 Author(s): VALLADARES, G. S.; PEREIRA, M. G.; BENITES, V. de M.; ANJOS, L. H. C. dos; EBELING, A. G.; GUARESCHI, R. F. Despite limited geographic expression of Organosols in Brazil, their high carbon storage capacity and natural environmental vulnerability justifies further studies on C and N stocks in these soils and... ... |

 Author(s): PASZKO, T.; MATYSIAK, J.; SPADOTTO, C. A.; BOGUTA, P.; SKIC, K. Our recent study demonstrated that fulvic and humic acids are the major contributors to the adsorption of phenoxyalkanoic acid herbicides in soils. At very low pH, the neutral forms of these herbicide... ... |
 Author(s): MARTINEZ-BALMORI, D.; SPACCINI, R.; AGUIAR, N. O.; NOVOTNY, E. H.; OLIVARES, F. L.; CANELLAS, L. P. Vermitechnology is an effective composting method which transforms different residual biomasses into nutrient rich organic fertilizer. In fact, the mature vermicompost is a renewed organic source suit... ... |
 Author(s): TADINI, A. M.; MARTIN NETO, L.; BERNARDI, A. C. de C.; OLIVEIRA, P. P. A.; MILORI, D. M. B. P.; PEZZOPANE, J. R. M. Soil organic matter (SOM) and their humic fractions (e.g., Humic Acids, HA) are considered a relevant soil quality indicator, due to its direct relation with biological, chemical and physical soil pro... ... |
 Author(s): MADARI, B. E.; LIMA, L. B.; SILVA, M. A. S.; NOVOTNY, E. H.; ALCANTARA, F. A. de; CARVALHO, M. T. M.; PETTER, F. A. Biochar incorporation into the soil is a proposed C sequestration strategy. How newly applied biochar affects C accumulation in the soil is therefore a relevant question. This study presents part of t... ... |
 Author(s): COELHO, E. F.; MELO, D. M. de; PEREIRA, B. L. da S.; SANTOS, D. B.; ROSA, R. C. C. This study aimed to evaluate the effects of fertigation with humic substances, with and without the addition of plant extracts, on the root system of the 'BRS Princesa' banana cultivar. The banana cro... ... |
 Author(s): FONTANA, A.; PEREIRA, M. G.; BALIEIRO, F. de C.; CHAGAS, C. da S.; DONAGEMMA, G. K.; OLIVEIRA, L. S de Soils with high organic carbon content, such as those with "humic A horizon", occur in different regions of Brazil. This study aimed to determine the quantitative and qualitative characteristics of or... ... |
