Short summary

Several experiments have confirmed the improvements in soil aggregation and infiltration achieved by no-tillage (NT) management associated with increases of bulk density. An increase in bulk density implies a reduction of the porosity that is in contradiction with the increased infiltration that occurs in macro and mesopores. We found that the reduction in total porosity under NT is mainly a product of a reduction of the mesopores. The results indicate NT did not affect the crop yields.
