Abstract
The plant infection count, also known as the most-probable-number (MPN) count, is used to determine the number of viable and infective rhizobia in the presence of other microorganisms. The trap legume selected in the MPN method must belong to the same cross-inoculation group of legumes nodulated by the rhizobia under investigation. This indirect method is commonly used to determine the quality of inoculants produced from nonsterile carrier materials. It is also used to determine the number of rhizobia in the soil.
