Optimización del proceso de elaboración y el uso de los abonos biofermentados (biol)

Abstract:

In “The optimization of the manufacturing process and the use of biofertilizers” It was analyzed the chemical, biological and bromatologic content of three biol formulations on three fermentation times. This essay was performed inside a greenhouse in Nulti (canton Cuenca). The fermentation process was developed in black plastic containers, hermetically sealed, provided with an exit valve system for gas resulting from boidigestion. The temperature, humidity and boidigester internal temperature was monitored every ten minutes. The biodigester internat temperature varies about 3ºC, this variation is directly proportional to the ambient temperature, thought the biodigesters internal temperature has a delay about 9h30 min with respect to the ambient temperature because of the rate of air heat transfer into the biodigester contents. The enrichment o the substrate with mineral salts increased the content of nutritious elements on the biol, this treatment present the highest value of electrical conductivity of the three formulations. The average performance of the three formulations was 144 biol liters, representing 90% of total water used inside the biodigester at the elaboration time. The prepared biol liter costs $0.29 (biol 1 and 3) and it was observed to increase the cost in Biol 2 due to the addition of mineral salts, giving a value of $0.34 per liter. The biol 2 was higher in nutrients compared with two foliar liquid fertilizers in relation to the cost of investment. The presence of auxins and gibberellins was observed in all three biol formulations by thin layer chromatography analysis
