The influence of PK and NPK fertilization on permanent and temporary grassland root system was studied in mountain region of Slovakia (Liptovska Teplicka, 960 m elevation) over five years (1993-97). It was confirmed that in most measurements 67% and 83%) the root weight of permanent and temporary grassland was increased. A root weight decline was detected in the rest of measurement. A comparison of average temporary grassland root weight to permanent one showed a decline to 56.5%. Root dynamics over growing period was different for both grassland types. Over studied five years period root system weight decreased to 4th year with an increase in last one
