Because of the new laws that govern our state, or maybe our county? We now have to consider the use of Phosporus when applying fertilizer. I didn't mind using commercial grade fertilizer with the higher cost. But, this year with now higher price in fuel, I am finding fertilizer compatible to what I'm looking for locally. But, is it cheaper?

32-0-8 1 ton=$676.00

Or

20-0-20 1 ton=$319.00

Area to cover:

420,000sq.ft.

On the bases of nirogen content at 2lbs per/1000sq.ft.

What would be your answer and why?
