Wisconsin grows potatoes only second to Idaho. Carrots and onions, too. BUT...they grow best north of here where the glaciers turned the stone to sandy soil as they were passing through, so loose soil is a must.
This sounds like a good root crop fertilizer mix to me:
2 cups alfalfa meal, 1/2 cup kelp meal, 1/4 cup rock phosphate, 1/4 cup bone meal
Blend and use the same day.

Thanks!
Not so easily done here in the Northwest, where cool weather stuff grows like the dickens...
Makes sense, thought. I have a stand of carrots(about 12 or so) from last year that I am letting go to seed this year and these suckers (tops) are HUGE! Over two feet tall! Stalks that are more like celery than carrots!
A gardening neighbor of sorts told me he had trouble with carrots but put wood ash on his garden, and they came out great. And I was kinda suspecting the primary ingredient in wood ash they would like would be the potassium part.
