Soil water content in surface layer in the area of neighbouring fields with different crops was measured with Time Domain Reflectometry and gravimetric method. The sampling points were situated in the nods of square net of 10 m x 10 m, containing the area of 40 m x 430 m. Spatial variability of soil water content was analysed with the use of classical statistics and the theory of random probability. Spatial dependence of soil water content for the whole investigated area was stated, although for the separate fields it was noticed or not. The range of soil water content variability changed depending on meteorological conditions and the type of the crop
