Elaboración de un abono (Bocashi) a partir de residuos orgánicos del Bioterio de la Facultad de Ciencias – ESPOCH.

Abstract

The objective was the elaboration of bocashi starting from the bioterium tamo of the ESPOCH Faculty of Sciences as the main organic waste. The benefits of using organic fertilizers such as bocashi are known worldwide. However, the scientific literature requires little about the nutritional contents, the pathogenic microbial load and the presence of Titotoxins in this type of fertilizer. To this end, 4 batteries with different mixtures described in the literature were mounted in the solid waste collection center of the ESPOCH; in the whole process Aeration, humidity, temperature, pH and electrical conductivity are controlled. The aeration was manual and was controlled according to the temperature, in general the batteries were turned twice a day for the first seven days, then only once a day. The bioxidative phase lasted 38 days and maturation 60 days, giving a total of 98 days. The determination of macronutrients (N, P, K) and phytotoxicity was performed on days 1.38 and 98 and the microbiological analysis at the end of the process. of P, K at day 38 were the highest, in contrast to those obtained at day 98, on the other hand N obtained higher concentration on day 98; the Germination Index (GI) as a phytotoxicity test at day 38 and 98 was very limited, except in cell 2; The microbiological results revealed the absence of E, coli in all the batteries and the presence of Salmonella in cell 2. In terms of performance, batteries 3 and 4 significantly reduced their mass unlike batteries 1 and 2.
