This study examined consistency of spatial variation of plant-available soil nutrients P, K, Mg and soil pH in two fields of an area of 54 and 67.5 ha (haplic Luvisol and luvic Chernozem) in the region of Ceský Brod (Central Bohe mia). Computed variograms showed a spatial dependence extending to 150 m on an average with small fluctuations for most analysed data sets. These results of two different fields indicate that soil spatial variation is rather a general feature than specific to every field. However, soil available Mg in one field showed a shorter-range (89 m) and soil pH in the other showed considerably longer-range (375 m). Consistency of spatial variation features makes it possible to construct regional average and proportional variograms with great precision. This can bring further practical opportunities.
