- Abstract
When cultivated areas are used with intense agricultural production, the soil presents spatial and temporal alterations in its hydrophysical attributes so that the economical viability of the agricultural production depends on those attributes, requiring detailed studies consequently about the spatial variability of the soil. Thus, the objective of this work was to evaluate the spatial variability of the saturated hydraulic conductivity and water infiltration in the soil, in an area of 20 ha, characterized by intensive grain production, was used a grid of 50 x 50 m grating, using the Guelph Permeameter. In the spatial variability analyses, geostatistics methods were used. It was concluded that the hydrophysical attributes studied presented structures of spatial dependence and behaved proportionally, but did not show spatial correlation in the 50 m density of studied.
