CAL, We used milorganite on plots last summer with what seemed to be positive results. Had a 1/2 acre plot of ICP make it all the way until the end of September before being eating down to nothing. planted second plot close by approximately the same size that did not have Milorganite applied and it was gone by early August. Not the most full proof use of the scientific method but did give a little information that it could have had an effect.

Those Beans look awesome BTW. Very nice
