Re: excessive phosphorus

I think you should send in soil samples to Midwest Labs and get their recommendations, because on here we don`t know your soil Ph and percent calcium.  And what kind of manure you`re using hog, chicken, liquid dairy with the analysis.  

 

Here`s DNR manure plan on over 500 animal units.

But just a guy on the internet, 216lbs of P doesn`t seem "excessive" to me. fwiw.
