Scientia Agropecuaria [online]. 2019, vol.10, n.3, pp.353-361. ISSN 2077-9917.  http://dx.doi.org/10.17268/sci.agropecu.2019.03.05.

The objective of this research was to evaluate the quality of the compost obtained from chicken manure, with inoculation of beneficial autochthonous microorganisms. The investigation was conducted for 13 weeks; At the field level, beneficial microbial consortia CMB1 of cabbage (Brassica oleracea) and CMB2 of lemon verbena (Cymbopogon citratus) were extracted, which were inoculated once a week at 5% concentration in the compost piles distributed randomly in complete block with three repetitions. Three treatments T1 (CMB1), T2 (CMB2) and T3 (Control) were established. It was determined that beneficial microbial consortiums suppress odors in the composting process, at the same time accelerate the degradation of organic matter which is evidenced in the hig her content of humic acids in the final compost compared to the control: T1 = (3-4%), T2 = (3%), (T3) = 1%. In the compost obtained with inoculation of CMB1 and CMB2, higher biological activity was determined: T1 = 3 ug/ml, T2 = 4 ug/ml, T3 = 1 ug/ml, in addition beneficial microorganisms in higher concentration were identified (log UFC.g^-1) as well as higher nutrient content with respect to the control treatment, therefore, of superior quality.
