New Hampshire

I want to raise my magnisium by 50ppm. How much epsom salt is needed for a 1000SqFt?

Jim,

50ppm is 100 lbs of Magnesium (as an element) per acre foot. So if you applied a 10% Magnesium version of Ag Grade Epsom Salts (check the label to be sure) then 1000 lbs per acre tilled to 12 inches or 23 lbs per 1000 sq ft. Thats a good deal more than I would apply at any one time (though some Rose growers are known to do this. YIKES!). I consider 10 lbs to be a heavy 1000 sq ft application. This will also lower the pH a bit.

What is the current pH? Like here, New Hampshire usually runs a bit acidic. If you are a little low, then some of that Magnesiun would best be delivered by applying some Dolomitic Limestone instead.

Let me know.
