This study was conducted to determine if alfalfa plants inoculated with the phosphate-solubilizing soil fungus Penicillium bilaii are able to source otherwise unavailable forms of soil P. A total of ten field trials were established throughout the major alfalfa producing regions of Saskatchewan in 1994 to determine the effects of inoculating alfalfa seed on the early season vegetative growth and P uptake, and forage yield response of alfalfa over a range of soil and climatic conditions. Increased alfalfa dry matter production, P uptake, and forage yield responses were observed following inoculation with P. bilaii, most likely the result of increased P availability from the solubilization of otherwise unavailable soil P. Penicillium bilaii is registered for use in Canada on wheat, canola, pea, and lentil under the trade name Provide®.
