Abstract

Slash-and-burn is one of the oldest agricultural systems used by man. The effects of this system on the physical and hydraulic properties of the soil are still controversial. Thus, this study aims to evaluate the infiltration and hydraulic conductivity in slash-and-burn in a cycle of two years of fallow and compare the hydraulic parameters of swidden agriculture with others tillage system. This work was carried out between the months of December 2012 and January 2013 in three areas tillage with beans and a forest area. They were carried out 18 infiltration tests using a drive voltage infiltrometer in each area, nine without application of voltage and nine with a voltage five centimeters of water. The slash and burn presented high rates of infiltration and hydraulic conductivity, similar to the minimum tillage. It is concluded that soil structure is essential for the soil water movement, and it was fundamental for the slash and burn and the minimum tillage to showed rates of infiltration and hydraulic conductivity superior to conventional tillage.
