| Summary: | Despite the knowledge that you have about the benefits of the humus of the worms or ver- micompost, there is a need to evaluate the technical feasibility of using other sources of carbon for worms. The objective was to evaluate the possibility of using straw of coffee to vermicompost production, the effects of their use on worms and on the quality of humus obtained. The evaluated treatments consisted of: (1 straw of coffee (SC) 100%; 2 SC 75% + manure (MA); 3 50% SC + 50% MA; 4 25% SC + 75% MA; 5 100% MA). The straw of coffee and the manure were incubated for 64 days to make them available to feed the worms and more 84 days to digest the substrate. The straw of coffee increased the number of worms without resulting in harmful effects. The percentage increment of the straw in the constitution of the vermicompost increased the availability of N, K, Ca and Cu, but it reduced the availability of Mg, S, Mn, P, Fe and Zn. Aiming o the medi- um supply of nutrients, the proportion of the 50% of straw of coffee and 50% of manure is designated. |
