CARACTERIZACIÓN FÍSICO-QUÍMICA Y MICROBIOLÓGICA DEL LIXIVIADO GENERADO DEL COMPOSTAJE DE EXCRETA PORCINA PARA SU USO COMO ABONO ORGÁNICO | PHYSICAL-CHEMICAL AND MICROBIOLOGICAL CHARACTERIZATION OF THE LEACHATE GENERATED FROM THE SWINE MANURE COMPOSTING FOR USE AS AN ORGANIC FERTILIZER

The aim of the present work was to characterize from the physical-chemical and microbiological point of view the leachate generated from the composting of swine manure with sugar cane bagasse (Saccharum officinarum) and grasses hay, star grass (Cynodon nlemfuensis) and pangola grass (Digitaria) decumbens Stent), for use as organic fertilizer by small pig producers in the peasant and cooperative sector of Cuba.

There was no presence of Salmonella spp., and a low population of Escherichia coli was observed. By comparing the results obtained with the internationally established standards, it is possible to use these products as organic fertilizer, taking into account the security and protection measures established
