Catabolic processes in the nodules of legumes affecting the nitrogen content of the plant

An attempt is made in this paper to prove the theory that the B.radicicola takes up free nitrogen from the atmosphere and builds it to protein for its body tissues, and afterwards this protein is broken down into amino compounds and thence to ammonia, which in turn is nitrified to the nitrate before it may be used by the host plant in its process of tissue building.

The soy bean strain of the B. radicicola and the soybean as the host plant were used throughout this study.
