Improvement of arbuscular mycorrhiza development by inoculation of soil with phosphate-solubilizing rhizobacteria to improve rock phosphate bioavailability (32P) and nutrient cycling

Article Abstract:

Biogeochemical cycles are influenced by bacterial and fungal agents in rocks. A microcosm experiment highlighted the influence of phosphate-solubilizing bacteria and arbuscular mycorrhizal fungi in the biogeochemical cycle of phosphorus. This influence is more than merely expanding the surface area where interactions take place but these organisms are also shown to actively participate in chemical cycling by altering concentration levels.

Assessment of natural mycorrhizal potential in a desertified semiarid ecosystem

Article Abstract:

A study was conducted to qualitatively and quantitatively determine the mycorrhizal status and spatial/temporal variations in propagules of arbuscular mycorrhizal fungi (AMF). A semiarid ecosystem in southeastern Spain was chosen as the study site. Results indicated that the indigenous inoculum levels of AMF are not enough to support a broad revegetation program when an additional mycorrhizal inoculum is unavailable.

Management of indigenous plant-microbe symbioses aids restoration of desertified ecosystems

Article Abstract:

Inoculating desert soil with indigenous arbuscular mycorrhizal fungi and rhizobial nitrogen-fixing bacteria can restore the quality of soil so that key plant species can be re-established. This is a necessary step when restoring areas affected by desertification because desertification damages soil as well as plants.
