Summary In field experiments on soils of different rooting density and different yield potential relationships between P uptake and root penetration of the soil, respectively, EUF-P contents in the topsoil were studied. On soils under uniform climatic and management conditions yields increased with increasing total root length in the subsoil (30–100 cm depth), while a negative correlation was found to exist between yields and total root length in the topsoil (0–30 cm). P removal was significantly correlated with the readily available water capacity of the rooted soil volume, which indicates the yield potential of a soil. There was no significant correlation between EUF-P contents of the soils and the P contents of the plants, but P contents in plant dry matter was significantly correlated with rooting density in the topsoil. Considering the effect on P contents of both EUF-P content in the topsoil and rooting density, the correlation coefficient was increased.
