“…Chemical and structural properties of humic substances have been studied by techniques such as: elemental composition analysis, Fourier transform infrared spectroscopy (FTIR), thermogravimetry and 13 C nuclear magnetic resonance ( 13 C NMR) (Dell'Abate et al, 2002;Castilhos et al, 2008;Gonzaléz-Pérez et al, 2008).…”

“…A vermicompostagem fornece material estabilizado, especialmente quanto ao pH, em tempo menor, se comparado com a compostagem (CASTILHOS et al, 2008). As análises revelaram a diminuição do pH em ambos os tratamentos.…”

“…The treatment of organic residues before their addition to the soil is crucial to minimize possible negative effects on human, soil, and plant health, such as contamination with pathogenic organisms (fungi, bacteria, viruses, and helminths), nitrogen immobilization due to the high C/N ratio of original residues, and undesired variations in soil pH in response to the residue's alkalinity or acidity. In this sense, vermicomposting is a low energy-demanding process that stabilizes the pH and lowers the C/N ratio of organic residues in a shorter time than the regular composting method (Castilhos et al, 2008;Cotta et al, 2015). The final product is more stable and nutrient-enriched than the original material, which are crucial properties for maximization of the fertilizing effect of vermicomposts and for optimization of machinery operations when these products are applied in the field (Hashemimajd and Jamaati-Somarin, 2011;Baldotto et al, 2012).…”
