Varietal differences in uptake of 32P labelled phosphate in clover plus ryegrass swards and monocultures



Varietal differences in uptake of 32P labelled phosphate in clover plus ryegrass swards and monocultures



Annals of Applied Biology 100(3): 559-565



Lolium perenne S23, L. multiflorum RvP and Trifolium repens S184 and Olwen were grown in mixed swards and monoculture in 1979. Whereas in mixtures grass roots absorbed more 32P than clover roots, in monoculture clover generally absorbed more 32P than grass roots. This showed that grass was a very strong competitor for uptake in mixed swards. Clover and grass monocultures absorbed most 32P from 10 or 15 cm depth in the soil, while grass in mixtures absorbed most 32P at 22.5 cm depth.
