Fertilizer grade ?

[dun]

As it applies to fertilizer what does N=12.55, P=25.1 and K=23.18 mean? Is that the % of the actual thing N/P/K per pound?
I was just looking over my fertilizer bill and got curious.

Thanks

Divide each number by 100 and it will give you the pound of fert needed to add 1 # to soil

I look at it as pounds per hundred wieght. Same thing. Fits in my head better.

The numbers are actual pounds of each per 100 lb. spread. The rest is filler.

So what exactly does it mean?

A 50 pound bag of 10-10-10 would contain 5 pounds each of nitrogen, phosphorus, and potassium. In other words, if you put a 50 pound bag of fertilizer on a garden you really didn't actually put much fertilizer. Hope that analogy helps.

It's the percentages of each in the mix. Never seen them get so tight as to add decimal points on the bill where I buy fertilizer but I bet I pay for what I get.

Once you start using units instead of pounds, then you'll start to have fertilizer figured out.
