The work was accomplished in Santa Luzia Farm in the municipal district of Cruz do Spirit Saint, PB. Located in the coordinates Lat 6° 56'52.21" S and Log 35° 7'57.01" O with the objective of verifying the space variability in what concerns the saturation of aluminum in Interchangeable Catiônica's Complex (ICC). the total area considered about experimental unit was of 49 ha. The area was divided in irregular mesh totaling 39 points, each collection point, besides the limits of the property, it was georreferenciado with a Geodesic GPS. The collection of the soil felt in trenches of 1 m3. The tenor of Aluminum in the first horizon of the profile of the studied soil presents characteristic of dependence fort, have seen the relationship n effect/ landing of < 25%. the saturation of aluminum is, in 61,5% of the area, normal and in the others 38,5% of the area demand correction.
