The N-P-K system is a shorthand way of referring to the percentage of nitrogen, phosphorus, and potassium in a particular mixed fertilizer. For example, a fertilizer labeled "10-10-10" contains 10% nitrogen, 10% phosphorus, and 10% potassium. Therefore, option A is the correct answer. Option B is partially correct but does not encompass the entire meaning of the N-P-K system. Option C and D are incorrect as they have nothing to do with the N-P-K system. Option E is incorrect as option C is incorrect.
