The behavior of dissolved reactive phosphorus in the soi! may depend on the different systems of soi! management, providing a timely management of impacts on the environment. The aim of this study was to assess lhe form of drag and reactive phosphorus in different types of ground cover offered and suggest alternatives to the traditional management in agricultural are as ofthe basins. The study was conducted in Lages, Se, between the November/2009 março/2010, a lnceptsoil under jive different types of crops randomly distributed, with two replications. There were three tests of simulated rain with 90 minutes in duration and intensity of 64 mm h-I, using rainfall simulator rotating boom type Swanson. The tests were carried out at 30, 69 and 105 days afier sowing. Losses of phosphorus in runoff varied with rainfall tests, but not with the types of farming system. The plots with soybean and corn were the bachelor results closer than expected, whi!e the plots of bare soi! and bean showed the highest difference of the expected behavior in relation to the behavior of reactive phosphorus in comparison to the total reactive phosphorus jiltrado. Com base this, it is suggested that management of small rural watersheds take into account the type of management that will be given to the ground in order to adapt where necessary physical structures to contain runof!. Likewise, the management should take into account the times that offer greater risk, which would be the time of planting and harvest, depending on the way it is made.
