Obtención de biol a partir de desechos orgánicos generados por el ganado bovino del Camal Municipal del Cantón Latacunga

Abstract

The present research studied the development of biol from organic waste generated by the bovine cattle of de municipal slaughterhouse in Latacunga County, Cotopaxi province. It began whit the collection of organic waste rumen and urine. Later in a PVC container of six liters water, yeast, molasses, whey, humus and ash were mixed respectively. Then they were subjected an Anaerobic decomposition phase for a period of fifty-five days. The process of fermentation or organic fertilizer was completed and an appropriate nutritional quality was obtained to improve the cultivation soil characteristics of the Latacunga municipal vivarium. Three treatments were analyzed: T1 (rumen), T2 (urine), T3 mix (rumen and urine mixture) whit three repetitions each one, and a witness treatment or control (manure). The research área was adapted, avoiding the interference of external variables and the analysis of variance was performed to determine significant diferrences in the treatments using the Tukey test. The research concluded that: The best treatment was the T3 which was prepared by mixing 14.16% of rumen, 14.16% of urine more 56.66% wáter concentrations of 177 ppm of N, 37,67 ppm of P, 6198,67 ppm of K, 1208 ppm of Ca, 695,33 ppm of S, 554,57 ppm of Mg, 0,79 ppm of Cu, 40 ppm of Fe, 3,69 ppm of Zn; It showed a pH of 7.1, electric conductivity, moderately saline of 18.7 mSiems/cm and a performance of 80%. It was determinated that the cost of a liter of biol from the rumen and the urine is 0.69 cents. The research recommended to the Municipal slaughterhouse administrator of Latacunga to create a use system of these wastes in situ, to preserve its natural characteristics in the development of biol and reduce transport costs.
