Organic carbon mineralization of the biochar and organic compost of poultry lit...
Tito, Gilvanise Alves; Fernandes, Josely Dantas; Chaves, Lucia Helena Garófalo; Guerra, Hugo Orlando Carvallo; Dantas, Edilma Rodrigues BentoThe dynamics of the organic residues added to the soil are closely related to its mineralization rate. Therefore, the present study aimed to evaluate the organic carbon mineralization in soil samples incubated with different doses of biochar and organic compost from poultry litter. Carbon mineralization was evaluated experimentally by measuring the C-CO2 liberated by incubating 200 g of soil mixed with differen...
Effect of vermicompost enriched with rock dust in soil chemistry and radish cul...
Tito, Gilvanise Alves; Chaves, Lucia Helena Garófalo; Souza, Felipe Guedes de; Cavalcante, Antonio Ramos; Fernandes, Josely DantasVermicomposting is the process of transforming the little degraded organic material into organic matter stabilized through the action of the earthworms and the microsymbionts. This study aimed to evaluate the effect of the addition of increasing doses of vermicompost enriched with rock dust (MB4®) on soil chemical characteristics and on radish (Raphanus sativus) production.The vermicompost was prepared by incub...
Acúmulo e translocação de cobre e zinco em plantas de Crambe abyssinica
Tito, Gilvanise Alves; Chaves, Lúcia Helena Garófalo; Vasconcelos, Ana Carolina Feitos deCrambe (Crambe abyssinica) é uma cultura promissora para a produção de biodiesel. No entanto, não há muita informação disponível sobre as técnicas e pesquisas sobre o melhor desempenho em diferentes regiões para explorar o seu potencial. Objetivou-se avaliar o efeito de cobre e zinco no acúmulo e distribuição destes elementos nesta planta. O estudo foi realizado em casa de vegetação e constou de dois experiment...
