This study aim to evaluate the spatial variability of soil physical attributes in of Alfissol forest inManicoré region, AM. The mapping of an agroforestry growing area of 70x70m was made using a
regular grid sampling of 10 x 10m. In each grid , soil samples were collected at 0.0 – 0.2 and 0,40 –
0,60 m depth, with a total of 128 sample points. Physical analyses were made (texture, soil bulk and
particles density, macro and microporosity, total porosity and aggregates stability in water).With
the exception of DMG, DMP and class aggregates <1.00 mm had all the physical attributes spatial
dependence structure ranging from moderate to weak. Values were above the range established
in the mesh (12.00 to 45.56 m), enabling to make a basis for future studies in forest area. The physical
attributes presented in kriging maps different spatial behavior, however there are relationships
between these attributes shown by geostatistics proving that this is effective tool for studies in forest
area.
