Resumo: | Microbial activity constitutes a good indicator of soil quality, and is influenced by the addition of carbon in the system serving as a substrate for microorganisms that increase their activity and release of CO2, comprising the edaphic respiration of the soil. The objective of this study was to evaluate the microbial activity in different soil types with the addition of cake press of castor bean and cotton textile residue. The study was conducted in a greenhouse at the headquarters of Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA) Cotton in randomized block design in 4 x 3 factorial arrangement with four replications. At predetermined intervals of 4 days, the containers were opened and the solution of NaOH titrated with HCl 2N in the presence of acid/base indicator phenolphthalein. After reading, the same amount of NaOH was added and the containers were closed again. The difference between the amounts of acid needed to neutralize the sodium hydroxide in a control container and the treatments was equivalent to the amount of carbon dioxide produced by soil microorganisms. It was found that the residues influenced the microbial activity in different soil types, especially in the initial determinations, presenting themselves as good sources for mineralization and nutrient supply, the castor bean proportionating higher cumulative release of CO2 by microorganisms. |

Objetivou-se, neste trabalho, avaliar a atividade microbiana em diferentes tipos de solo com a adição de torta de mamona e resíduo têxtil de algodão. O trabalho foi conduzido em casa de vegetação na sede da Embrapa Algodão, em delineamento de blocos casualisados em esquema fatorial 4 x 3, com quatro repetições. A intervalos predeterminados de 4 dias os recipientes foram abertos e a solução de NaOH foi titulada com HCl 2 N na presença de indicador ácido/base fenolftaleína. Após a leitura a mesma quantidade de NaOH foi reposta e os recipientes novamente fechados. A diferença entre a quantidade de ácido necessária para neutralizar o hidróxido de sódio no recipiente testemunha e nos tratamentos equivale à quantidade de gás carbônico produzido pelos micro-organismos do solo. Constatou-se que os resíduos influenciaram significativamente a atividade microbiana nos diferentes tipos de solo, sobretudo nas primeiras determinações, apresentando-se como boas fontes para mineralização e fornecimento de nutrientes, tendo a torta de mamona proporcionado maior liberação acumulada de CO2 pelos micro-organismos.Universidade Estadual Paulista Júlio de Mesquita Filho Faculdade de Ciências Agronômicas UNESP/FCA, Rua José Barbosa de Barros 1780, Fazenda Lageado, CEP 18610-337, Botucatu, SPEmpresa Brasileira de Pesquisa Agropecuária (EMBRAPA) Algodao, Campina Grande, PB, BrazilUniversidade Estadual Paulista Júlio de Mesquita Filho Faculdade de Ciências Agronômicas UNESP/FCA, Rua José Barbosa de Barros 1780, Fazenda Lageado, CEP 18610-337, Botucatu, SPUniv Estadual Paulista, Fac Ciencias Agron, UNESP FCA, BR-18610337 Botucatu, SP, BrazilUniversidade Federal da Paraíba (UFPB) CcsaUniversidade Estadual Paulista (Unesp)Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA)Capuani, Silvia [UNESP]Rigon, João P.G.
