摘要：

An anion-exchange procedure in which soil samples are shaken with polyester-netting bags containing a strongly basic resin has proved to be the only method too date which yields reproducible 'plantavailable' P estimates on Marion Island soils. Available P determinations using chemical extractants are hampered by high iron, aluminium and organic matter contents in these soils. Resin-extractable soil P levels correlated strongly with plant leaf P contents at a wide variety of sites. © 1979 Martinus Nijhoff Publishers.
