This research is based on obtaining compost by applying biological activators EMAs, EM y Surfixx-R and Best Ultra-F to accelerate decomposition of organic matter Was performed randomized complete block design (RCBD) with four trials with three replications; in a time of 13 weeks. When start the process the color of the waste was typical of the bark of fruit and vegetables, with the passage of time was observed from wastes similar to brown-ground hue. The average temperature in the mesophilic stage of biological activators and control was 18.42°C. After five days of composting start a thermophilic phase occurred with an average temperature of 53.8°C; EMAs highest temperature reached 56.9°C and the lowest S-B 50.6°C. In the maturation phase treatments the average temperature was 30.7°C, getting the highest value EMAs with 32.6°C and the lowest control 28.9°C. Moisture is related to temperature because if there is no good low temperature drastically. Aeration is important in this job because if frequent turning is not performed decreases the O2 generating an anaerobic decomposition. The values of temperature and humidity control were minimal as no biological activators is used compared to the treatments. The values of nutrients: NT, P2O5, K2O, MOnot had differences between treatments.
