Obtención de Biofertilizante a partir del contenido ruminal generado en el centro de Faenamiento municipal del cantón Portoviejo

Abstract

This research work proposes an ecological alternative for the revaluation of the waste generated during the slaughter process; The content in the rumen is considered one of the contaminants with the greatest impact on the environment; it is also a source of large quantities of nutrients and microorganisms that can be useful in the production of fertilizers. Therefore, the present study focused on obtaining biofertilizer from the rumen content generated in the Municipal Slaughter Center of the Portoviejo Canton. Initially, sampling of rumen content (untreated) was developed based on microbiological parameters and elements such as nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, boron, zinc and copper. Parameters of: organic carbon, nitrogen and carbonnitrogen ratio were evaluated for the applied treatments. The biofertilizers were developed in three treatments (T1, T2 and T3) at room temperature and 60 °C for 1-2 months. The results obtained showed that the best treatment was T3, denoting the absence of pathogenic agents such as E. coli and Salmonella, while the macronutrients of nitrogen, phosphorus and potassium with values of 1,12%, 0,18% and 0,61% , respectively, pH 7,1; humidity 23,33%, organic carbon 12,75% and C/N ratio 11,37%. It is concluded that the biofertilizer under the criteria of the Mexican standard NADF-020-AMBT-2011 considering that the macronutrients NPK are <7% and C/N <15, it has been classified as a fertilizer of type A, whose main characteristic is the improvement of substrate soil for nurseries and substitute for potting soil.
