This is a link to FINBIN which represents about 10% of the farms in MN that gross over $250,000.00. These are the results from after the 2013 crop year. I think the 2014 year should be out shortly as these results came out the end of March last year. It shows that about 20% of the represent farms had over 60% debt to asset ratio, and half the farms had under a 40% debt to asset ratio. This is only for about 2200 farms in MN so it could be way different than other areas and other states. I think it will be pretty interesting to see what the %s are after the 2014 year. I also think 2012 could make the %s vary a lot  and most of MN had a very good year in 2012.
