Changed line 5 from:
The analysis prouded on a fertilizer package refers to the amount of an element present in a formulation based on percentage of weight. All fertilizers are labeled with three numbers, giving the percentage by weight of nitrogen (N), phosphate (P2O5), and potash (K2O) respectively. Often, to simplify matters, these numbers are said to represent nitrogen, phosphorus, and potassium, or N-P-K. We should remember that it is not N-P-K, but N, P2O5, and K2O. Moat fertilizers contain no P2O5, and K2O, but phosphorus and potassium are expressed as the amount of fertilizer would contain if they were in P2O5 equivalent, and K2O form equivalent. (These forms of expression are leftovers from the early days of chemistry, when all elements were expressed as oxides.) For example, if we have a 100 pound bag of fertilizer labeled 10-10-10, it contains 10 pounds of N, 10 pounds of P2O5, and 10 pounds of K2O. To convert the P2O5 content to actual phosphorous content, multiply the given weight by 0.43. To convert K2O content to potassium content, multiply the given weight by 0.83. The rest of the fertilizer's weight is filler. to:
