Abstract: 
Nitrogen uptake from non-exchangeable .**GRAPHIC**. by Lolium multiflorum and availability of fertilizer .**GRAPHIC**. and fertilizer .**GRAPHIC**. were studied in pot experiments with three different soil types. The luvisol derived from loess released considerable amounts of non-exchangeable .**GRAPHIC**. when cropped. In this soil fertilizer .**GRAPHIC**. was only weakly fixed and was as available to the crop as fertilizer .**GRAPHIC**. The recovery of fertilizer .**GRAPHIC**. was even higher than the recovery of fertilizer .**GRAPHIC**. In the fluvisol (alluvial soil) and in the cambisol (brown earth from basalt) N recovery was higher from .**GRAPHIC**. fertilizer than from .**GRAPHIC**. fertilizer. In these soils .**GRAPHIC**. fertilizer was strongly fixed by 2:1 clay minerals and thus less available to the grass. Particularly in the basaltic soil the content of non-exchangeable .**GRAPHIC**. was low and so was the release of nonexchangeable .**GRAPHIC**. At the same time this soil showed the strongest fixation of fertilizer .**GRAPHIC**. Release and refixation of fertilizer .**GRAPHIC**. in the loess soil appears to be an important feature of this soil type with a beneficial effect on soil nitrogen turnover and availability.
