The three most important plant nutrients are nitrogen, phosphorus, and potassium. NPK fertilizers are named for the chemical symbols of these elements: N for nitrogen, P for phosphorus, and K for potassium. Fertilizers are marked with the percentage of each of these nutrients. For example, a fertilizer may be marked as 18-51-20, which means it is 18% Nitrogen, 51% Phosphorus, and 20% Potassium. You may notice that these numbers do not add to 100% - the remainder is made up of "fillers". Fillers prevent the nutrients from clumping together and "burning" the plant.

The purpose of a soil test is to determine the nutrient content of the soil. This will allow the gardener to select plants that will grow best in the existing soil conditions or to determine what nutrient supplements are required to amend the soil for the intended plants.
