Concentrations of microbial phosphorus in soils range between 0.75 for the mineral layer of a sandy Spodosol planted with loblolly pine (Grierson et al., 1998) and 184 mg/P kg for the litter layer of a planted pine forest (Ross et al., 1999). Microbial phosphorus contributes between 0.5% of the total phosphorus in grassland soils of New Zealand (Chen et al., 2000) and 26% of the total phosphorus in the litter layer of an indigenous broadleaved-podocarp forest, also in New Zealand (Ross et al., 1999). In mineral topsoil layers, microbial phosphorus increases in the order arable < forest < grassland (Tables 7.4, 7.5 and 7.6), but there is extensive overlap. Similarly to microbial carbon (Smith and Paul, 1990), soil type, texture and related soil organic...

The brome grasses occur in both permanent pasture (e.g. meadow brome) or as weeds of arable land (e.g. sterile or barren brome). Improved varieties of bromes (e.g. Grasslands Matua) have been introduced in the past from New Zealand but have proved unsuccessful due to lack of persistency under UK conditions.
