Original language description

In 1998 - 2000 the effect of fertilization on the quantity, stratification of root biomass and yields of dry mass on mesophyte meadow stands was studied. The root dry matter in the soil depth of 0.0 - 0.25 m was oscillating and the extreme values in individual samplings were found in 1998 (402 - 702 g/m2). In 1999 and 2000 the oscillating minimum and maximum values of dry underground mass in all variants were 418 - 622 g/m2, 423 - 678 g/m2 respectively. The mean values of dry root mass in unfertilised variants ranged from 484 to 540 g/m2. PK increased the values insubstantially (507 - 565 g/m2). The higher nitrogen dose (200 kg/ha) decreased predominantly the total quantity of dry underground biomass by 36-102% was found in the check variant, comparedin the yield of dry harvestable above-ground mass. In the systematic P40K100 fertilization the root weight in slightly moisten years (1998 and 2000) was by 18 - 70 % higher in comparison with the dry year 1999 when the root mass was 24 %
