Elaboración de abonos solidos (bocashi, compost) utilizando excretas de caninos

Abstract

The present research work was carried out at the “Santa Teresita” Animal Welfare Center located in San Roque neighborhood of Guano Canton, Chimborazo Province, 24 km from Riobamba city, at an altitude of 2700 meters above sea level. The objective was the elaboration of a solid fertilizer (compost, bocashi) using canine excreta, for which formulations of vegetative and domestic waste material were made, the content of N, P, K, Ca, Mg, Fe, Cu and Mn was evaluated, which are within the maximum permissible according to the Chilean regulation Nch2880. It was concluded that the compost at the end of the process obtained a pH of 7.60 and for the bocashi a value of 7.45 was obtained at the end of the process, therefore the temperature and pH did not vary their results during the process of elaboration of the solid fertilizers, taking into account that it is within the range according to information from the National Institute of Agricultural Research of Ecuador, that in previous investigations the pH for the compost is found in a value of 5 to 8.5 while the bocashi is found with a value of 6 to 9. Iron (Fe), Manganese (Mn) according to the allowed ranges for both the Compost and Bocashi which is < 800 - < 1500 it was determined that the values obtained in our research are above the range with values of 5145 at the beginning and at the end of the process is at 3375 for Compost and values of 5071.6, at the beginning and at the end of the process is at 2375 for Bocashi. Based on the results obtained, it was found that the decomposition process helps in the reduction of pathogens present in the initial phase of the research phase while at the chemical level, the solid fertilizer with the best results is compost due to the good presence of minerals, as verified by laboratory analysis. An important thing to consider is the experimentation time used in one of the fertilizers, since the completion of the cycle can generate better results.
