In the present investigation, an accelerated organic fertilizer was prepared on a pilot scale through the lactic fermentation process, using pig excreta and vinasse as a source of organic matter, molasses as a source of carbohydrates, and the microbial consortium was also used. Gar–Lac. Four pilot tests were carried out in a 30 L stainless steel bioreactor, at an average constant temperature of 40 ºC, for seven days in each test. The incorporation of the inputs was: 80% organic matter (pork excreta and vinasse), 10% molasses and 10% Gar – Lac. Every day of the fermentation process, the pH and % lactic acidity were evaluated, a decrease in pH was observed, having an initial pH of 5.23 and at the end 3.24 was obtained; While the % of lactic acidity increased, it started with 0.26% and ended with 1.31%. In the accelerated liquid organic fertilizer, the physicochemical characteristics of 44.40 g/L of M.O., 6870.47 mg/L of total N, 2190.10 mg/L of total P and 8443.75 mg/L of total K were obtained, these are values higher than those compared. and with respect to micronutrients, the good quality of the fertilizer is also identified. The accelerated organic solid fertilizer was obtained at the M.O. of 85.25%, N of 1.79%, P2O5 of 1.58% and K2O of 2.10% are values similar to the results of the comparative investigations; The results of the microbiological analyzes show that the fertilizer obtained is a safe product without pathogenic microorganisms, which reinforces and increases its good quality. The average efficiency in production in relation to total input input and total output is 81.6%; and by obtaining the liquid form an efficiency of 92.09% was obtained while the solid part was 7.91%.
