The paper presents lysimeter tests, which have been conducted since 1974 on the amount of water runoff from sodded soil profile under conditions of its diversified use and watering. On the tested area a major portion of the total yearly runoff from grasslands occurs during the growing season due to the amount and distribution of precipitation in this region (c.a. 68 of the total yearly precipitation falls during the growing season). Runoff values from grasslands recorded during the study period varied from 113.7 to 247.1 mm. A significant relationship has been found betwen the amount of water draining away from grassland soil profile and the amount of yield, which was caused either by a method of use (meadow, pasture or 8-15 cm high sward) or by the amount of applied nitrogen fertilization
