 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): 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): 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): 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): DIAS, R. de C.; FERREIRA, J. B. N.; LOIOLA, J. A. D.; GONÇALVES, R. G. da M.; TEIXEIRA, P. C.; STAFANATO, J. B.; ZONTA, E. The objective of this work was to evaluate the efficiency of granulated fertilizers based on potassium chloride with humic acids in the production of dry matter and the accumulation of macronutrients... ... |
 Author(s): CAVALCANTI FILHO, P. F. M.; BAÍA, D. C.; RIBEIRO, R. C.; ROSA, R. C. C.; CANELLAS, L. P. The management of organic fertilization in passion fruit has been carried out empirically based on the responses of the crops and the experience of farmers. Knowledge of the physiological responses of... ... |
 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): AGUIAR, N. O.; OLIVARES, F. L.; NOVOTNY, E. H.; CANELLAS, L. P. Plant growth-promoting bacteria (PGPB) and humic acids (HA) have been used as biostimulants in field conditions. The complete genomic and proteomic transcription of Herbaspirillum seropedicae and Gluc... ... |
 Author(s): CLEMENTE, Z.; MARTINEZ, D. S. T.; CASTRO, V. L. S. S. de Sustainable development of nanotechnology requires the deep evaluation of the safety of its products. Despite nanotoxicological studies have been intensified in recent years, gaps remain in the method... ... |
 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... ... |
