"For Southeastern soils with kaolinitic clays, a base saturation of 45 to 65 percent will be satisfactory for good plant growth."  ??? satisfactory... good... seems average  If that is OK, great!  With this scenario net production
ROI will likely be in lower 2/3's of all production acres.  Not a good situation with what is about to come in production agriculture with input cost inflation and limited access to capital.  At least the Fed has promised same M1 money flow (ie. interest rates) for the next two years.

Typical row crop farm operator business acres results each year from 40+ years of experience... 15% negative net (out of business within 3-5 yrs),  35% net 0 to 3-5% ROI (need at least one and likely two off-farm income(s) for family living expenses),  35% net 5-12% ROI (usually one off-farm income for family living, health benefits, some (extras), 15% net enough to continue to buy farms cash flow earnest money to put in 1 to 1.5 crops.  With grain, bushels win every time.  It's a value judgement of how to do it.  Right JH.
