Evaluación de diferentes formulaciones de microorganismos eficientes en el período de descomposición de los desechos orgánicos urbanos en el sector Belén, cantón Loja

The present research work was carried out in the Belén neighborhood of the Sucre parish to the south-west of the Hoya de Loja, with an altitude of 2 060 meters above sea level. The objective was to evaluate the influence of efficient microorganisms (EM) on the variation of factors: Temperature, Humidity and pH to determine the time and degree of decomposition of urban organic waste. A completely random design (DCA) with four treatments was used (T0: Control; T1 Microcompostic; T2 Trichotic; T3 Microspore) and four repetitions, installing wood-based compost bins with a volume of 0.15 m3 and consisting of 31 kg of waste, under a dosage of 50 cc / l of EM water. For the statistical analysis of data, the Infostat software was used using analysis of variance (ANOVA), and to evaluate the statistical differences, orthogonal contrasts were used using the 95 % Tukey Test, ending with the taking of samples for the respective chemical analysis of the compost in the Soil Laboratory of INIAP. At the end of the composting process, the Temperature presented statistical differences between the control and the formulations of efficient microorganisms (p < 0,001), with T1 and T3 reaching maximum values of 60,9 °C and 61,7 °C, compared to T0 whose upper value was 32,3 °C. Humidity showed a similar average of T0: 51,39 %, T1: 52,18 %, T2: 52,93% and T3: 53,05%. The pH, on the other hand, showed an inverse relationship to the increase in temperature, highlighting the T1 and T3 with slightly acidic values of 5,9 and 5,8. Microcompostic degraded organic waste in the shortest time (12 weeks), as well as presented the best nutritional content N: 1,86 %, P: 1,49 %, K: 1,10 %, M.O: 31,32 % and obtained the highest average of composted material 9,3 kg, compared to international compost quality standards NTC 5167 and NCH 2880 meets the maximum permissible limits.
