This may be a shotgun approach in that the many species will ensure that some will grow well depending on the conditions. Many claims about the potential benefits of cover crops need more data, especially long-term field trials of five years or more, to determine the pros and cons—and the economic impact—that cover crops might have. Sesbania is very valuable as a green manure or cover crop. The purpose is to control potential wind and blowing soil damage to fragile cotton seedlings. Increased water infiltration rates and storage capacity.

The establishment of a cover crop between rows of trees combined with a herbicide treatment to remove vegetation leaving a bare circle beneath each tree is practiced by many producers.
