Estudio sobre la contaminación del suelo después de tres ciclos de crianza de cerdos con el sistema de cama profunda a pequeña escala

Abstract

This paper concerns the results of physical, chemical and microbiological studies to the soil after three breeding cycles of pigs in deep bed system at small scale. The physical and-chemical parameters included organic matter, pH, total phosphorus and total nitrogen. The microbiological analyses were: Salmonella spp., fecal coliforms and helmints eggs. For the statistical analysis of the results was applied to analysis of variance, using a mathematical model of simple classification. In the soil samples are not significant differences for organic matter, nitrogen and phosphorus at the beginning and end of the three breeding cycles: (15.4 vs 14.4; 0.39 vs 0.43 and 0.45 vs 0.40) respectively. There was not an increase of fecal coliforms and Salmonella spp. in it and not found viable helmints eggs. It was concluded that the deep bedding system in the swine production at small-scale after three breeding cycles, not generates pollution to the soil.
