“…We presumed in that process AMF could lose the cation and release it in mycorhizosphere like carbon cases. Our observation was supported by Fitter and Garbaye (1993) that AMF can modify its interaction with other organisms in the soil, such as root-inhabiting nematodes and fungi, mutualists and notably nitrogen-fixing bacteria. In the mutualistic interaction, AMF showed its ability to work together with Azospirillum, Pseudomonas and Trichoderma.…”

Arbuscular mycorrhizal fungi (AMF) are ubiquitous organism that forms association with the root of most terrestrial plants. AMF association also influence soil fertility through the enhancement of chemical, biological and physical content. In this study, we enumerated AMF spores from rhizosphere of Tithonia difersivolia as an indicator of soil fertility. The results showed that the most fertile soil had the highest AMF spores density. This research has confirmed that AMF has high interaction with organic carbon, organic matter, total phosphorus, cation exchange capacity, water level, soil fungi and soil bacteria. Partial regression analysis revealed the mathematic equation for their interaction. This equation used the abundant of AMF spores as an indicator for chemical, biological and physical fertility of the soil.

“…These compounds can range widely in function but a large proportion appear to be involved in inhibiting the growth of bacteria and other fungi (Keller et al, 2005). A major area of research in mycorrhizal ecology is the role of EM fungi in protecting plants from root pathogens (Marx, 1972;Fitter and Garbaye, 1994;Nagy and Fossdal, 2013). EM fungi have been shown in numerous studies to ward off fungal and bacterial root pathogens using secondary compounds.…”

a b s t r a c tThe turnover of ectomycorrhizal (EM) fungal biomass represents a significant input into forest carbon (C) and nutrient cycles. Given the size of these fluxes, understanding the factors that control the decomposition of this necromass will greatly improve understanding of C and nutrient cycling in ecosystems. Recent research has highlighted the considerable variation in the decomposition rates of EM fungal necromass, and patterns from this research are beginning to emerge. In this article we review the research that has examined both intrinsic and extrinsic factors that control the decomposition of EM fungal necromass and propose additional factors that may strongly influence EM fungal necromass decomposition and ecosystem properties. We argue that, as with most plant litters, the stoichiometry (C:N) of EM necromass is an important factor governing decomposition, but its role is modulated by the nature of the C and N in the tissue. In particular, melanin concentration appears to negatively influence the quality of EM fungal necromass much as lignin does in plant litters. Other intrinsic factors such as the morphology of the mycelium may also play a large role and suggest this as a focus for future research. Extrinsic factors, such as decomposer community activity and physical protection by soil, are also likely to be important in governing the decomposition of ectomycorrhizal necromass in situ. Finally, we highlight the potential importance of EM fungal necromass diversity and abundance in influencing terrestrial biogeochemical cycles. Understanding the factors that control the decomposition of EM necromass will then improve the predictive power of next-generation terrestrial biosphere models.

“…Not surprisingly, Rhizobium can also influence AM development and colonization. It was previously believed that AM colonization could be directly linked to inoculation with Rhizobium and the resulting increase in nitrogen fixation ͑El- Kherbawy et al 1989;Fitter and Garbaye 1994;Hodge 2000͒. However, Xie et al ͑1995͒ demonstrated that increased AM colonization in the presence of Rhizobium is actually linked to the production of plant flavonoids related to host nodulation factors triggered by inoculation with Rhizobium.…”

The Center for Agroforestry at the University of Missouri has tested numerous native legumes for potential use in agroforestry and selected Illinois bundleflower ͑Desmanthus illinoensis ͑Michaux͒ MacMillan ex Robinson and Fern.͒ and panicled tick clover ͑Desmodium paniculatum ͑L.͒ DC.͒ for further testing. Our objective was to document the effect of arbuscular mycorrhizae ͑AM͒ ͑Glomus spp.͒ and Rhizobium on growth and nutrient concentration of these legumes. Seeds were planted in a greenhouse and inoculated with one of two species of AM and/or one of two strains of Rhizobium. Plants were harvested after 80 d and data taken on leaf and stem dry weight, root fresh weight, stem height, nodulation, AM colonization, and N, P, K, Ca, and Mg concentration. Inoculation with Rhizobium did not affect plant growth in Illinois bundleflower, but colonization by Glomus intraradices increased all plant growth variables except stem height. Nutrient concentration was unaffected by the presence of either endophyte. In contrast, inoculation of panicled tick clover with Rhizobium str. 41Z10 increased leaf dry weight ͑32%͒ compared to the control and root fresh weight ͑41%͒ compared to str. 32Z3, and colonization by G. intraradices increased leaf dry weight ͑35%͒ and stem height ͑26%͒. Both species of AM increased P and K concentration ͑41% and 55%, respectively͒ in panicled tick clover. Our results suggest that the growth of these legumes can be improved by the use of proper AM species and/or Rhizobium strains. However, additional research to identify the best Rhizobium and AM inoculates for these plant species is important in developing strategies for their use in agroforestry.
