Detailed explanation-1: -These three numbers form what is called the fertilizer’s N-P-K ratio-the proportion of three plant nutrients in order: nitrogen (N), phosphorus (P) and potassium (K). The product’s N-P-K numbers reflect each nutrient’s percentage by weight.
Detailed explanation-2: -NPK refers to the three nutrients that constitute complete fertilizers: nitrogen, phosphorus, and potassium.
Detailed explanation-3: -The three letters, N, P, and K, correspond with three numbers that indicate the percentage of each nutrient in that particular product. For example, a product marked 10-10-10 contains 10 percent nitrogen, 10 percent phosphorus and 10 percent potassium. A bag marked 20-20-20 containers twice as much of each nutrient.
Detailed explanation-4: -The three numbers on fertilizer represents the value of the three macro-nutrients used by plants. These macro-nutrients are nitrogen (N), phosphorus (P), and potassium (K), or NPK for short. The higher the number, the more concentrated the nutrient is in the fertilizer.
Detailed explanation-5: -Nitrogen (N) and phosphorus (P) availability limit plant growth in most terrestrial ecosystems. This review examines how variation in the relative availability of N and P, as reflected by N : P ratios of plant biomass, influences vegetation composition and functioning.
