Co-compostaje de gallinaza de la Granja Avícola Fernandita de la ciudad de Riobamba.

Abstract

The present research was carried putt in the waste disposable collection center in the higher studies Chimborazo University, with the purpose of treating the chicken dung generated in the Fernandita poultry farm of Riobamba city, by means of the organic waste technique of Co-composting mixed with pruning and grass as structuring agents, obtained from green areas of the ESPOCH. The organic residues waste were characterized to transform, adjusting the link carbon-nitrogen ratio. For the experiment, were put together four treatments with the following characteristics: Pile 1 (305 Kg of chicken dung + 40 Kg of pruning), Pile 2 (370 Kg of chicken dung + 85 Kg of pruning), Pile 3 (310 Kg of chicken dung + 25 Kg of pruning + 25 Kg of grass) and a treatment in Drum: (65 Kg of chicken dung + 20 Kg of grass). During the process temperature, humidity and aeration system were controlled. A total of 34 samples were taken analyzing pH, CE, % MO and for initial and final samples % IG, N, P, K to evaluate the quality of the compost obtained, demonstrating that they will be the permissible limits of a quality product. The organic matter of the stack 3 presents the physicochemical, chemical and biological properties which are most appropriate for its application in the agricultural sector.
