Abstract
El objetivo de este estudio es mejorar el proceso de compostaje en la Granja Modelo Pairumani (GMP), a través de la elaboración de compost con una relación C/N inicial adecuada y la adición de preparados biodinámicos. Para lograr este objetivo se realizaron ocho tratamientos de compost descritos a continuación: T1 (Estiércol, C/N = 15); T2 (Estiércol + preparados biodinámicos, C/N = 15); T3 (Estiércol + chala de maíz picada, C/N = 25); T4 (Estiércol + chala de maíz picada + preparados biodinámicos, C/N = 25); T5 (Estiércol + gallinaza, C/N = 14); T6 (Estiércol + gallinaza + preparados biodinámicos, C/N = 14); T7 (Estiércol + gallinaza + chala de maíz picada, C/N = 25); T8 (Estiércol + gallinaza + chala de maíz picada + preparados biodinámicos, C/N = 25). Durante el proceso de compostaje se realizaron evaluaciones en campo y análisis en laboratorios para determinar la influencia de la relación C/N inicial y la adición de preparados biodinámicos en el proceso de compostaje de la GMP. Las evaluaciones realizadas permitieron observar que los tratamientos elaborados con una relación inicial C/N=25 mostraron mejores características químicas, físicas y microbiológicas para un compost maduro. Por otra parte se vio la influencia de los preparados biodinámicos en la etapa termófila ya que los tratamientos con preparados biodinámicos presentaron temperaturas significativamente más elevadas que los que no tenían preparados biodinámicos.
The aim of this work was to improve the process of compost in the Model Farm of Pairumani, through the elaboration of compost with an adequate initial relation of 15 C/N and the addition of biodynamic preparations. To fulfill this objective the next 8 treatments of compost were made: T1 (Manure, C/N = 15); T2 (Manure + biodynamic preparations, C/N = 15); T3 (Manure + grinded corn foliage, C/N = 25); T4 (manure + grinded corn foliage, + biodynamic preparations, C/N = 25); T5 (manure + hen droppings, C/N = 14); T6 (manure + hen droppings + biodynamic preparations, C/N = 14); T7 (manure + hen droppings + grinded corn foliage, C/N = 25); T8 (manure + hen droppings + grinded corn foliage, + biodynamic preparations, C/N = 25). During the process of compost, field and laboratory evaluations were made to determine the influence of the C/N initial relation and the addition of biodynamic preparations in the process of compost at the Pairumani Model Farm. The evaluations allowed us to observe that the treatments elaborated with a relation of 25 C/N showed a better chemical, physical and microbiological characteristics for a mature compost. On the other hand, we observed the influence of the biodynamic preparations in the thermophile stage because the treatments with biodynamic preparations showed higher temperatures than the ones without biodynamic preparations.
