Soil moisture is a variable of great importance for the management of water in agricultural crops. The recent use of irrigation in forage cactus areas induces the need to measure soil moisture to aid decision making when and how much to irrigate. Therefore, temporal stability and spatial variability of soil moisture in a yellow red argisol cultivated with forage cactus were evaluated in this study. The experiment was conducted in municipality of Serra Talhada, State of Pernambuco, in a forage cactus area with dimensions of 76 x 32 m and diagonal slope of 0.6%, where soil moisture measurements were carried out in 60 positions (sampling points equidistant in 7 m), every 0.10 m, in six layers, until depth of 0.60 m and at intervals of three days for 41 days. Descriptive statistics, position relative difference, Spearman correlation matrix and geostatistics were applied. The moisture along soil profile showed a medium dispersion (10-20%) even after irrigation or rain events. The technique of the position relative difference showed that spatial dispersion of soil moisture depended on the layer. The Spearman correlation matrix detected temporal stability of the moisture in all analyzed layers, but more intense in the greater depths. Geostatistics revealed dependence between moisture of the soil cultivated with forage cactus and measurement position, and a close relation to the points with greater temporal stability.
