Recipe for combining greensand & sulfate of potash

emyers
15 years ago

Soil report says I'm low/medium in need of potassium.

Want to make sure potassium deficiency is not causing some of my gardening problems thus far.

So, based on soil report, says I need to add 10 lbs greensand per 100 sqft.

I also have a bucket of certified organic sulfate of potash.

Found a recommendation @ "norganics" quoted as follows....

"If there is an immediate need for available potash, it is suggested that Greensand plus, (a combination of greensand and natural sulfate of potash with 17 percent soluble potash) or Natural sulfate of potash (contains 52 percent soluble potash) be used.

What I want to do is match this 17 percent recipe, but don't know how much greensand and sulfate of potash to use.

Can anyone help me with a formula?
