"Following upon the fundamental discoveries, made principally in the last two decades of the nineteenth century, which revealed the essential part which soil bacteria play in the maintenance of soil fertility, considerable attention was devoted to the question of adding cultures of bacteria to the soil or applying them to the seed with the object of exerting a stimulating effect on plant growth. Leguminous crops were the chief subject of study on account of the peculiar relationship which these plants bear to special groups of soil bacteria. ... To encourage the more general practice of inoculation the Dominion Experimental Farms and certain of the agricultural colleges have been engaged in distributing cultures, while in addition, various commercial concerns have placed them on the market. ... The purpose of this bulletin, therefore, is to give Canadian farmers a better understanding of the purpose of inoculation, the principles underlying the use of bacteria as aids to soil fertility, and furthermore, the limitations of inoculation"--Introd., p.
