Management systems resulted in rapid changes in some soil properties as soil respiration and bulk
density. Our results showed that the organic farming practices resulted in lower soil bulk densities and
higher soil microbial activity measured by soil respiration, and organic carbon. This was caused by the
higher inputs of organic matter an energetic substrate for the present microbial communities that were
activated to assure the turnover of applied nutrients.
