Tratamiento mediante vermicompostaje de residuos orgánicos generados en el mercado huagra corral en la parroquia izamba, cantón Ambato

Abstract

This study aimed to prepare two vermicomposting beds using vegetable residues from the Huagra Corral market in the Izamba parish of the Ambato canton and guinea pig fertilizer. Initial residue analysis was performed, and the Corg/Nt ratio was calculated to determine the proportions for each bed. The treatments were: BED 1: 300 kg of market waste (RM) + 700 kg of guinea pig fertilizer (AC); BED 2: 500 kg of RM + 700 kg of AC. Before beginning the vermicomposting process, pre-composting was carried out to prepare the substrate for the worms. In this stage, the temperature and humidity of the beds and the environment were monitored. Turnings were made every 15 days, taking a representative sample in each turning to analyze physical-chemical, chemical and biological parameters such as humidity (H), organic matter (MO), pH, electrical conductivity (EC), Carbon-Nitrogen ratio (Corg/Nt), polyphenols, heavy metals, anions, macronutrients, micronutrients and germination index (GI). There was OM degradation in the two vermicomposting beds, the pH was essential, and the EC increased. The Corg/NT ratio was less than 20, and the polyphenols presented high concentrations that decreased slightly during the process. The concentrations of heavy metals and macronutrients were below the permissible limits. The germination rate was less than 50%, higher in bed 1. Finally, it is recommended to continue with the research to promote the production of organic fertilizers and their potential use as a soil amendment.
