It makes a very large growth of vegetable matter to be resolved into humus. On the basis of ten tons of green vines per acre, the crop contains 150 to 200 pounds of nitrogen with ten or twelve pounds in the roots alone. The nodules produced on the roots by the nitrogen-collecting bacteria are much larger than those found on the roots of our common legumes. They are brownish black in color, warty, broad, flat, and frequently measure an inch and a quarter across. The interior is greenish white or greenish pink in color.
