Abstract :In present study, geostatistical techniques was applied to assess the spatial variability of exchangeable cations such as; calcium insert ignore into journalissuearticles values(Ex-Ca 2+ );, magnesium insert ignore into journalissuearticles values(Ex-Mg 2+ );, potassium insert ignore into journalissuearticles values(Ex-K + ); and sodium insert ignore into journalissuearticles values(Ex-Na + ); in the tillaged layer in a Perm State Agricultural Academy Farm site in Perm region, West Urals, Russia. A 250x100 m plot insert ignore into journalissuearticles values(approximately 2.35 ha); was divided into grids with 25x25 m spacing that included 51 sampling points from 0-0.2 m in depth. Soil reaction insert ignore into journalissuearticles values(pH); was the least variable property while the Ex-K was the most variable. The greatest range of influence insert ignore into journalissuearticles values(237.6 m); occurred for Ex-Ca and the least range insert ignore into journalissuearticles values(49.7 m); for Ex-Mg.
