This is study from the comparison between the characteristics of soil water and the content of nutritious under two different situation: soil with forest vegetation and soils without forest vegetation. We were done a following of date of pedological wet, organic matter, pH, nitrogen and phosphorus content. The work was done in Bovril Town (situated in North West Province Entre Ríos, Argentine, 31° 22’ S.L. and 59° 30’W. L. The soils were belong to the serie San Carlos (Vertic Argiudol). The control meditions were done under six (6) situations in forest zone and without forest zone There was an increase in the pedological wet in forest zone up to 70 mean while the zone without forest was up to 40 cm. At this point there was a decrease up to 130 cm (maximum deep of medition). The humidity loss in 40 cm X = 2,35 % (forest zone) and the X = 3,95 % zone without forest. The organic matter, nitrogen and phosphorus level indicated dates higher in the soils with forest vegetation than in the soils without forest vegetation; these dates suggest a sustainable in the forest systems in wet -mild climate.
