Should not be a problem as you apparently replaced the nutrients. Corn is a very heavy feeder and continouos planting will suck the life out the soil unless you make the effort to rebuild it. Soil borne diseases are rarely a factor with corn.

Agree with farmerdill. Didn't the indians tell the early settlers to put a dead fish in each hill of corn? Gives you an idea of what an aggressive feeder it is. I'd also put some 10-10-10 in the row and then also sidedress with same.

The indians also advocated "the three sisters," which were corn, beans and squash in the same hill. Squash may be as aggressive feeding as corn, explains why the indians changed garden areas often. :-)
