Nutrisphere & Avail?

[gertman]

Have any of you added Nutrisphere and/or Avail to your granular fertilizer mixes?
Was it worth the price ($65-$70 a ton here)?

I use Nutrisphere in my mix when I use ammonium sulphate. I think it only adds a $3-5/acre to the cost. So far it looks like its worth the cost.
