Excerpt: . . . that a plant like a bean utilises the nitrogen of the soil until it is driven by starvation to make the nitrogen of the nodules its source of supply. In view of the enormous importance to practical agriculture of the nitrogen-collecting power of the leguminous nodule bacteria, a number of experiments have been made all over the world to see if anything could be gained by introducing an increased or possibly a more vigorous supply of these organisms into the soil. It has been shown, in fact, that although there is only one species, as it may be called, of bacterium associated with leguminous plants, yet that species possesses a certain amount of racial adaptation, so that clover which has been infected from a clover nodule grows better than if it had been infected from a bean nodule. In some cases this specialisation has gone so far that the particular leguminous plant can only be infected from another plant of the same kind or by soil in which it has been grown; it responds very indifferently to the neutral form of organism that is present in cultivated soils and adapts itself to most of the leguminous crops it meets. Moreover, from time to time, particularly in new countries or where heath or bog or salted alkali land is being reclaimed for the first time, soils are met with which do not contain any nodule organisms, so that when leguminous plants are sown they neither develop nodules nor fix nitrogen. These considerations have led to the artificial inoculation of the soil with the organism appropriate to the desired crop, either by spreading over the land a small quantity, half a ton per acre or so, of soil taken from a field in which the crop in question had before grown successfully, or by sprinkling on the seed an artificial culture. . .
