You need to act fast so Gypsum at 100 lbs/M or better yet use Solucal & gypsum 50/50.

SOP 0-0-50 20 LBS/M.

Leave the pH alone for now.

Why not last fall?

100lbs gypsum for 500 sq ft? Solucal sounds like the way I need to go.

I was already planning to add 10 lbs of SOP this spring for a 500 sq ft plant.

I think he is saying 100lbs per 1,000'sq M=1000

m=1000

I'm still trying to figure these soil tests out - Is Nic adding the gypsum (calcium sulfate) because his calcium is low (if 2677 ppm is low) or is it because his pH is high (7.4) - although I thought I read that gypsum does not effect pH.

So I should add Potash to lower potash ? Huh. I got some gypsum will add at last till Saturday morning.

The results of my test seem weird. I added 10lbs of sop and some manure last fall and my potassium sky rocketed from 100 to 512.

M=1000 SQ FT so 20#/M is 10 lbs/500 sq ft.

Solucal is quicker than regular gypsum. Use it if you can.

Is this a newly acquired site Nic?

At the rate AGs feed, CA & K are good bets even if the test report doesn't indicate a deficiency.

This is a new spot I added a lot of amendments last fall so it is not like I am just now getting the patch ready. I thought I would just have to do a few minor changes. I looked At past data from other growers I thought over 500 ppm on potassium was too high.

500 ppm K is high but look at your MG. You could skip the K but SOP is gentle. As the season goes these cation elements will slide into balance. AGs are heavy CA & K magnets.
