SUMMARYSoil-borne spores and hj^phae of arbuscular mycorrhizal fungi are important propagules in cracking clay soils of northern NSW, Australia. In these soils, senescent roots were uncommon. Although c. 4-200 spores g~^ soil were found, less than 6 % established arbuscular mycorrhizas in trap plants, and this percentage declined over 24 months. Using tetrazolium red as a vital stain, 16-21 % of spores from field soils were found to be viable in fresh soil and 6-7 % after 24 months of storage. Using fluorescein diacetate, the length of stained hyphae of c. 0-5 m g~^ soil was shown to be halved over 32 wk. The density of viable propagules of arbuscular mycorrhizal fungi in soil declined over time and was reduced by severe disturbance. The fungi that survived to 12 months included a species thought to form dormant spores, while those initiating infection after 24 months, did not.

“…All five soils were collected in 1968 by Wood (1970Wood ( , 1974, who reported on rates of biomass decomposition (Wood 1970) and earthworm communities (Wood 1974); these papers also contain detailed information about the formation and properties of soils of this region. At this time, the soil taxonomic scheme in use in Australia was the classification scheme of Great Soil Groups (Stace et al 1968). Under this scheme, soils A1053, A1054 and A1055 are classified as Alpine Humus and soils A1056 and A1507 are classified as Podosols.…”

The composition of organic phosphorus in soils of the Snowy Mountains region of south-eastern Australia

Abstract. Few studies have considered the influence of climate on organic phosphorus (P) speciation in soils. We used sodium hydroxide-ethylenediaminetetra-acetic acid (NaOH-EDTA) soil extractions and solution 31 P nuclear magnetic resonance spectroscopy to investigate the soil P composition of five alpine and sub-alpine soils. The aim was to compare the P speciation of this set of soils with those of soils typically reported in the literature from other cold and wet locations, as well as those of other Australian soils from warmer and drier environments. For all alpine and sub-alpine soils, the majority of P detected was in an organic form (54-66% of total NaOH-EDTA extractable P). Phosphomonoesters comprised the largest pool of extractable organic P (83-100%) with prominent peaks assigned to myo-and scyllo-inositol hexakisphosphate (IP 6 ), although trace amounts of the neo-and D-chiro-IP 6 stereoisomers were also present. Phosphonates were identified in the soils from the coldest and wettest locations; a-and b-glycerophosphate and mononucleotides were minor components of organic P in all soils. The composition of organic P in these soils contrasts with that reported previously for Australian soils from warm, dry environments where inositol phosphate (IP 6 ) peaks were less dominant or absent and humic-P and a-and b-glycerophosphate were proportionally larger components of organic P. Instead, the soil organic P composition exhibited similarities to soils from other cold, wet environments. This provides preliminary evidence that climate is a key driver in the variation of organic P speciation in soils.

“…Higher porosities would likely offer larger contact areas between the medium and H 2 S, and thus the high porosity of cg 5 reflects the engineered nature of this commercial medium. The two red soils tested in this experiment were both classified as krasnozems (Great Soil Group, Stace et al, 1968) or red ferrosols (Australian Soil Classification, Isbell, 1996). By definition, ferrosols have free iron-oxide contents greater than 5% Fe in the fine earth fraction (<2 mm) of the B2 horizon (Isbell, 1996).…”
