Distribution of arbuscular mycorrhizal fungi on organic farms in Gasa, Bhutan

Bhutan envisions to become gOrganich by 2020. Gasa, which we set as an investigation place, has already been declared an gOrganic Dzongkhag (District)h in 2008. Phosphorus is one of the major nutrients for crop growth but is often poorly available in arable soils. It is well known that arbuscular mycorrhizal fungi (AMF) which colonize plant roots symbiotically stimulate phosphorus uptake through their hyphae. In this study, for effective utilization of AMF, we intend to clarify the distribution, population density and species composition of AMF on the pilot farms for organic agriculture in Gasa, Bhutan.
