Microbial phosphorus is quantified after fumigation of soil with chloroform or hexa-nol to kill soil microorganisms (Brookes et al., 1982). The various modifications of the method, especially in terms of extractants and use of calibration factors, are described elsewhere in this volume (see Oberson and Joner, Chapter 7). For highly weathered tropical soils, the fumigation-extraction method with anion exchange resin membranes (Kouno et al., 1995) or Bray (NH F-HCl) extraction (Oberson et al., 1997) may be most suitable.
