Abstract
Microorganisms and their interactions in the soil play a critical role in nutrient transformations and cycling, and in sustaining soil productivity. Arbuscular mycorrhizal fungi (AMF) playa major role in nutrient cycling. Phosphate solubilizing bacteria (PSB) on the other hand playa role in phosphorus nutrition by enhancing its availability to plants through release from inorganic and organic soil phosphorus pools by solubilization and mineralization. Activity and composition of microorganisms in soil are influenced by management practices such as the choice of crop species and fertilization. Application of AMF in sweetpotato production can contribute to increased growth, increased yields and improved soil nutrition with a reduction in chemical fertilizer input in a more sustainable agriculture.
