Properties of Agave angustifolia Haw. bagasse before and after its composting.
Keywords:Biodegradation, organic fertilizer, organic substratum, reuse of residues.
The industry of mezcal (Agave spp.) in Oaxaca, Mexico annually generates more than one hundred thousand tons of bagasse. With the aim of using this by-product as an alternative organic substratum, there were analyzed the physical, physicochemical and chemical properties before and after the composting of the bagasse of the A. angustifolia Haw with 0, 90 and 180 days of aging. Before the composting, all the physicochemical properties were different for the aging periods except for humidity and dry matter. During the composting process the temperature of the three materials was superior to 58oC, and after 105 days it was obtained mature compost, free of feces. The physicochemical and chemical properties of the three composts were different for the aging periods and most of them were not placed between the reference intervals, except in the C/N relation, contrary to most of the other physical properties.
