Minnesota/Kentucky fertility based on ENERGY | FWIW you will never raise soluble calcium with gypsum, that doesn't mean you won't get a calcium reading on a soil test but gypsum will move calcium, due to the chemistry and the interaction of sulfur!
Friend in the thumb of Michigan has been 10 plus years using a blend of gypsum and high calcium lime and has had great response! Some may say what is the difference and the lime react differently.
Or the use of the bottom ash that Mr Schlapkohl has used over the years in Iowa works well to mellow soils and keep calcium in check |
