Evaluación de la eficiencia de tres activadores biológicos aplicados a pilas de compostaje ubicadas en San Francisco de Cruz Loma

Abstract

ASOCRUZLOMA association, located in a paramo ecosystem makes composting with the waste generated from its agricultural, livestock and tourism activities. Due to the climatic conditions of the area, the slow composting process returns with a minimum duration of 6 months, which is why the compost cannot be used in its short-cycle crops, with this premise the process applying biological activators becomes necessary. At present a total of 1100 kg of biodegradable waste was used, with which 3 composting piles were armed with whey, 3 with alfalfa ferment, 3 with native efficient microorganisms (EMAs) in different concentrations and 3 composting piles for control with the objective of optimizing its maturation time. Solid waste characterization was carried out following the methodology presented in the PAHO Solid Waste Characterization Guide. To determine the maturity state of the compost, the parameters of temperature, pH and humidity were controlled, while to evaluate the quality of the compost, NT, MO, C/N ratio, electrical conductivity, apparent density and fecal coliforms were obtained. The indicative results of the composting piles with EMA biological activator reach maturity in 15 weeks and produce a quality A compost, which is why the EMA biological activator is efficient, reducing the maturation time by 50% from 6 months to 3 months, followed by whey and finally alfalfa ferment.
