Most fertilizers have three major nutrients necessary for plant growth: nitrogen, phosphorus, and potassium (denoted as N-P-K). Choose a crop that you would be interested in growing (e.g. flowers, corn, potatoes, etc.) and determine which major nutrient (i.e. nitrogen, phosphorus, and potassium) is most important for your crop. Determine the amount of fertilizer you would need to maximize your crop yield.
