I always read on nat about apply potash 1 year before so it is avaiable. I don't get this. 0-0-60 is very water soluable. Put some in a bucket. Put in a little water and melts. Spread it on top 2 - .4 inch rains and its gone. Now its in the soil solution it is ready to be used. I have ask Carry L. from U of WI about this. Ask her the same question how long does it take to be available. She said they have looked at the on sand like I farm. Said that once it mild she thought it would be available and on plainfield sand the soil test levels spike right after application and that 6 week later it was back down again. Leaches that fast in sand. yes, Florida Potato growers have been practicing the same application timing and methods for decades from the 60's as I personally recall. I find that 90% of the information concerning K and K applications, soil base levels are Mythical at best. ON Your farm work, documentation is critical for YOU. |
