Typically fertilizers are broken down into 3 numbers (e.g. 20-10-10). I believe the first is nitrogen, the second is phosphorus and the thrid is potassium; though I may have mixed up the last two.
I be once told what each did specifically for plants and was curious if someone have that information, or a good, clearly explained, link to it.
Also I believe blood collation is a good nitrogen source and bone meal is apt for phosphorus, does anyone know a good, organic, potassium source?
Answers: The three numbers on your shoulder bag of fertilizer are referred to as the "analysis." It is the percentage of nitrogen, phosphate and Potassium (Potash typically) that is available to plants from that bag of fertilizer. (e.g. 20-10-15). 20 = Nitrogen, 10 = Phosphate, 15 = Potash
These are correct references on Fertilizers:

I "googled" organic Potash and get (plus others, you might find more...):

sul-po mag is a great source for organic potassium. Rock phosphate is far better than bone meal for phosphate.
Using NPK is an outdated approach to look at feeding the soil brought to us by the chemical agriculture people. Plants and soil want around 90 different nutrients to be healthy and whole.
know that the most earth-shattering crop any organoc grower rows is soil and NPK will not grow great soil alone.
