Within the past few years a number of commercial concerns have produced a dry dust type of culture for the inoculation of legume seeds. Field experiments have been conducted to test the value of these cultures for the inoculation of soybeans. The results showed that the dry dust cultures did not give satisfactory inoculation. Greenhouse experiments have also shown that the inoculation of legume seeds sometime in advance of the planting date, as is recommended by the producers of the dry dust manufacturers, is undesirable.
