Oops, i meant P2O5. You are absolutely correct. My bad.
Im so glad im not doing this event anymore. Im bad at it =(

Ok, thanks. Anyone found anything on digesting soil yet?

I can't be for certain, but here are my theories. What do you guys think?

A) Acid will cancel out the bases, and the resulting soil will be comepletely neutral, with some possible weak bases.
B) Acid will dissolve unneeded materials and leave neutral things behind?

I read this whole thread and now I am very confused. What is the chemical formula for N-P-K? I read several different answers.

Good question. I'm also confused about that.

Phenylethylamine and msaifee are both correct. Really it doesn't mean anything. Nitrogen also used to also be stated in the oxide form a long time ago, but they decided to change that into elemental...but kept the rest the same for some reason. You aren't going to likely find much of those elements in that oxide form in either fertilizer or in soil.

Really, the point seems to just be to make calculations for people in this event somewhat more difficult because you have to calculate the moles elemental form (P/K) in a given mass of P/K compounds and then convert that into the mass of P2O5 or K2O to get the answer that would be stated on the fertilizer. Might want to keep the numbers .44 and .83 handy for quicker conversions between elemental and oxide forms of those two.

Oh okay thanks, i went back and re-read what they said and it makes sense now.

there are actually formulas for commonly used N, P ,or K compounds. I cant recall them now, but try looking in a gardening or horticulture textbook, they have good info on that

Hmm, both theories sound plausible, but for some reason the first one is jumping out at me.. I don't know?

The first one seems more believable to me.
