Notes:
Summary A chlorotic condition of soybeans in the river valleys of eastern Nebraska was studied. The pattern of chlorosis, presence of petiolar necrosis, reductions in rhizobial and mycorrhizal infection, and plant and soil chemical analyses suggest that the condition is more complex than normal iron deficiency chlorosis or other mineral deficiencies or toxicities. Nodulation is almost totally inhibited in affected plants. Mycorrhizal fungi, while able to infect early in the season, do not persist on affected plants. Breakdown of endodermis was observed in the roots of affected plants. The factors contributing to this condition have not yet been determined.
