Description
Annually, the tequila industry generates thousands of tons of agave and millions of liters of vinasse. Mostly, they are not adequately treated and contaminate the environment. Composting has been the most widely used technology for the treatment of bagasse and occasionally for vinasse as well. However, just one report of large-scale composting have been found, and studies using bagasse compost as substrate for growing agave in containers have not been located. For these reasons, this research had the following aims : 1) the characterization of large-scale composting process of bagasse by assessing physical and chemical parameters as well as a population dynamics study of the most important microbial groups involved in composting : bacteria, fungi and actinomycetes, 2) physical and chemical characterization of finished bagasse compost, and 3) the evaluation of different types and mixtures of bagasse compost as substrate for the cultivation of agave in containers. The study was conducted in a compost pile with an initial weight of approximately 331 tons which was monitored during 300 days ; the compost samples were analyzed chemical, physical and microbiologically. The investigation of compost as substrate for agave cultivation was held in a nursery and agave fields for two successive years ; a total of 31 blends and seven types of bagasse compost were assessed
