Abstract
A study was undertaken to evaluate the composting process with two different horticultural waste substrates: (1) a mixture of pepper, cucumber and bean plants and (2) pepper plants, and the effect of inoculation with Trichoderma sp. was analysed. Four piles at semi-pilot scale were built and periodically turned and aerated. Moisture content was maintained at 50–60%, and the temperature monitored daily. Microbial, physical and chemical parameters were followed during the process.
Thermophilic phase was reached within 2 days in all piles and maintained for 24–32 days. After this time, temperature decreased until its stabilization at environmental levels. Physical and chemical parameters evolution suggested a suitable process in all piles, although horticultural wastes mixture seemed to be slightly more appropriate as substrate. Inoculation of horticultural wastes mixture led to a faster decrease of C/N ratio and a higher formation of humic substances.
