Phosphorus and Potassium

[spencer52356]

I received my soil sample results that show I am low on Phosphorus and Potassium for my clover plot. It recommends applying 9.18lbs of 0-20-20 and 1.53lbs of 0-0-60 for my .33acre plot. Where are you guys purchasing bags of phos and potash? Every bag I find has nitrogen and low phos and potash.

Thank you
Corey

Any local co-op or Ag Services dealer should have 6-28-28 or 6-24-24.

For that little amount you can find at Home Depot or even Amazon.

I was off on my calculations. I actually need 25.2lbs of phosphate and 39.2lbs potash

Is that per acre or per your 1/3 acre area?

I picked up some 50 lb bags of 6-24-24 and 0-0-60 in the spring from Des Moines Feed and Nature Center on Hubbell.

That's for my .33 acre.

One 50# bag of 6-24-24 (Units per 100#) would get you 3-12-12 for one acre, or 9-36-36 for your 1/3 acre. About perfect.

Bassattackr,
Thank you! I still had not figured out the proper way to calculate that. Once you wrote it out, it all made sense.
