Organic phosphorus can be found in rock phosphate, bone meal and various liquid organic fertilizers such as Neptuneâs Harvest Fish & Seaweed. Potassium (K), sometimes known as potash, is important for general health of plants.
Why Is This So Complicated? Why report values for P2O5 and K2O instead of the elemental P and K? It is a historical thing. The tests chemists used to use measured P2O5 and K2O and not P and K. So they reported fertilizer NPK numbers as %P2O5 and %K2O. In most countries we still do that today.
