Descrição: dc.descriptionMicrobial 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 Embrapa Cotton in randomized block design in 4 × 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.-
