title: Indirect methods of determination of activity of root-nodule bacteria.
abstract: Significant correlations exist between the ability of root-nodule bacteria to fix molecular nitrogen and some of their properties (accumulation of riboflavin, cobalamine, ATP, cell pyrolysis, effect on plant vegetation characteristics) which can be used for quickly assessing the activity of the process in individual strains of rhizobia.
