SOIL-PLANT INTERRELATIONS AND VEGETATION BOUNDARIES ALONG AN ELEVATION GRADIENT IN A HUNGARIAN SODIC GRASSLAND Márta. ZALATNAI, László KÖRMÖCZI, Tibor TÓTH Abstract: In a 30 m transect soil-plant interrelations and vegetation boundaries influenced by edaphic factors were studied with moving split window (MSW) techniques. Boundaries between vegetation patches were sharp lines on the basis of both visual observation and MSW analysis but the boundaries between the different soil sections separated by MSW analysis were wider. Factor analysis showed that in the four vegetation sections separated by MSW the correlation coefficients were significant between plant and soil at p<0.01.
