“…Also, our observation that, in the two native prairie sites, AM fungi produced up to 87% more hyphae in their home soil (Fig. 4B) implies that locally adapted fungi have the potential to sequester more carbon and nutrients in their extraradical hyphae than nonadapted fungi (9,10). In addition to AM-hyphal biomass inputs to the soil-carbon pool, the filamentous hyphae help create a physical framework for stabilizing primary soil particles into larger, relatively stable soil aggregates.…”

“…In addition to AM-hyphal biomass inputs to the soil-carbon pool, the filamentous hyphae help create a physical framework for stabilizing primary soil particles into larger, relatively stable soil aggregates. By generating these aggregated soil structures, extraradical hyphae increase soil stability and create conditions that favor the protection of detrital inputs (8,9). Although the contributions of AM hyphae to this mechanism are important for both Fermi and Konza soils, they may play an even more crucial role in the more coarse-textured sandy loam at Cedar Creek (8).…”

“…Parasitic mycorrhizas can develop in fertilized soils if carbon costs of the symbiosis do not outweigh the mineral benefits (4,5,7). Glomeromycotan fungi have also been shown to improve soil structure and are important carbon and nutrient sinks in many ecosystems (8)(9)(10). Thus, understanding the factors that control their abundance and symbiotic function can help guide their management so that their desirable community and ecosystem functions can be maximized.…”

Symbioses may be important mechanisms of plant adaptation to their environment. We conducted a reciprocal inoculation experiment to test the hypothesis that soil fertility is a key driver of local adaptation in arbuscular mycorrhizal (AM) symbioses. Ecotypes ofAndropogon gerardiifrom phosphorus-limited and nitrogen-limited grasslands were grown with all possible “home and away” combinations of soils and AM fungal communities. Our results indicate thatAndropogonecotypes adapt to their local soil and indigenous AM fungal communities such that mycorrhizal exchange of the most limiting resource is maximized. Grasses grown in home soil and inoculated with home AM fungi produced more arbuscules (symbiotic exchange structures) in their roots than those grown in away combinations. Also, regardless of the host ecotype, AM fungi produced more extraradical hyphae in their home soil, and locally adapted AM fungi were, therefore, able to sequester more carbon compared with nonlocal fungi. Locally adapted mycorrhizal associations were more mutualistic in the two phosphorus-limited sites and less parasitic at the nitrogen-limited site compared with novel combinations of plants, fungi, and soils. To our knowledge, these findings provide the strongest evidence to date that resource availability generates evolved geographic structure in symbioses among plants and soil organisms. Thus, edaphic origin of AM fungi should be considered when managing for their benefits in agriculture, ecosystem restoration, and soil-carbon sequestration.

“…Arbuscular Mycorrhizal (AM) fungi account for 5-50% of the biomass of soil microbes (Olsson et al, 1999). Biomass of hyphae of AM fungi may amount to 54-900 kg ha -1 (Zhu and Miller, 2003) and some products formed by them may account for another 3000 kg (Lovelock et al, 2004). Pools of organic carbon such as glomalin produced by AM fungi may even exceed soil microbial biomass by a factor of 10-20 (Rillig et al, 2001).…”

Sustainable development has caught the imagination and action of the world for more than a decade. Sustainable agriculture is necessary to attain the goal of sustainable development. According to the Food and Agriculture Organization (FAO), sustainable agriculture is the successful management of resources to satisfy the changing human needs while maintaining or enhancing the quality of environment and conserving natural resources. All definitions of sustainable agriculture lay great emphasis on maintaining an agricultural growth rate, which can meet the demand for food of all living beings without draining the basic resources towards crop improvement. Organic farming is one of the several approaches found to meet the objectives of sustainable agriculture. Most of the techniques used in organic farming like intercropping, mulching and integration of crops and livestock are not alien to agriculture systems including the traditional agricultural practices. However, organic farming is based on various laws and certification programmes, which prohibit the use of almost all synthetic inputs and the central theme of this method is the health of soil. The adverse effects of modern agricultural practices on the farm and also on the health of living beings and thus on the environment has been well documented all over the world. Application of technology, particularly the use of chemical fertilizers and pesticides all around us has persuaded people to think aloud. As a result of global climatic changes, their negative effects on the environment are manifested through soil erosion, water shortages, salination, soil contamination, genetic erosion, Organic farming is one of the widely used methods, which is thought as the best alternative to avoid the ill effects of chemical farming. It also has far more advantages over the conventional and other modern agricultural practices that are available today.

“…Cardoso and Kuyper (2006) reported that AMF is playing role in the carbon cycling, consequently increasing AMF will increase carbon flow into soil. Interaction between host plant and AMF indirectly affect soil carbon storage (Zhu and Miller, 2003) especially because carbon flow from host to AMF can lose into mycorrhizosphere up to 70% as organic carbon and CO2 (Jakobsen and Rosendahl, 1990). In addition, AMF also produce glomalin which can store soil carbon (Driver et al, 2005).…”

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.
