ResumenEl objetivo de esta investigación fue evaluar la calidad del compost obtenido a partir de estiércol de gallinas, con inoculación de microorganismos benéficos autóctonos. La investigación se realizó durante 13 semanas; a nivel de campo se extrajo consorcios microbianos beneficiosos CMB1de col ( Brassica oleracea) y CMB2 de hierba luisa (Cymbopogon citratus) los cuales se inocularon una vez por semana al 5% de concentración en las pilas de compostaje distribuidas en bloque completos al azar con tres repeticiones, se estableció tres tratamientos T1 (CMB1), T2 (CMB2) y T3 (Testigo). Se determinó que los consorcios microbianos benéficos suprimen los malos olores en el proceso de compostaje, a la par aceleran la degradación de la materia orgánica lo cual se evidencia en el mayor contenido de ácidos húmicos en el compost final en comparación con el control: T1 = (3-4%), T2 = (3%), (T3) = 1%. En el compost obtenido con inoculación de CMB1 y CMB2 se determinó mayor actividad biológica: T1 = 3 ug/ml, T2 = 4 ug/ml, T3 = 1 ug/ml, además se identificaron microorganismos benéficos en mayor concentración (log UFC.g -1 ) así como más alto contenido de nutrientes con respecto al tratamiento testigo, por tanto, de calidad superior.Palabras clave: Consorcios microbianos; compostaje; industria avícola; estiércol. AbstractThe 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.
