Caracterização química de compostos e vermicompostos produzidos com casca de arroz e dejetos animais

Abstract: RESUMO Dejetos animais representam importantes fontes de nutrientes para as plantas; entretanto, necessitam de estabilização para evitar contaminação ambiental. Juntamente com a casca de arroz, podem ser usados em compostagens e vermicompostagens e reinseridos no sistema produtivo. Neste estudo, foram elaborados compostos e vermicompostos com casca de arroz e dejetos de aves, bovinos e suínos, que, após estabilização biológica, foram avaliados quanto à composição química e fracionamento de fibras, relacionando… Show more

“…In a short period of 15-20 days, the existence of hummus is already noticeable, reaching a usable volume after 50-60 days (FELICIO et al, 2018). According to Vione et al (2016), vermicomposts that have germination rates above 100% are considered convenient for cultivation, as they generally contain substances that stimulate the germination process. It should be noted that treatment 3 showed the best rates in all germination analyses throughout the vermicompost maturation process.…”

“…Works such as Wu et al (2019), Duan et al (2019), and Jiang et al (2018) highlight the importance of monitoring pH values, with a low pH delaying the increase in temperature, prolonging the composting process, and stimulating the growth of fungi that aid in the decomposition of lignin and cellulose found in sawdust. Vione et al (2018) obtained pH values that ranged from 6.5 to 8.2, in compost s matured from bovine, swine, and poultry manure. According to the authors, the ideal pH should be slightly acidic to neutral, since values greater than 8.4 can be harmful to plants, especially if associated with odors and the loss of ammonia.…”
