Burlington, IA | If going to beans on CRP ground, using inoculant is a must, even the universities suggest that. The reason is that the native strains in the soil will be seriously depleted, if not extinct, by being out of beans for so long. Twice the normal rate of inoculant is also recommended. Same situation also applies to beans going into continuous corn ground, hay, pasture, or ground that has been flooded out or had water laying on it for awhile. Reason for the latter is that the water turns the ground anaerobic, and the inoculant bacteria is an aerobic critter. It needs oxygen present in the soil in order to survive and operate, and dies off in an anaerobic environment.
Use of an inoculant on CRP ground will be a big help to your beans, if you go that way. Good luck.
