It is widely accepted that a healthy plants require a certain amount of nutrients to achieve their fullest potential, however the specific nutrients required are subject to each specific plant. Most soilsare able to provide sufficient nutrients to sustain a plant, but today humans are able to add additional nutrients through fertilizer to the soil to allow the plant to thrive. In a study conducted on ice burg lettuce, a compound fertilizer at a constant nitrogen to phosphorus to potassium ratio was added to the lettuce as itwas growing. It was indicated that with the more frequently the lettuce was fertilized, the yield significantly increased. It was also indicated that the less frequently the lettuce was fertilized, the yield significantly decreased. This was found to be due to nutrient deficiency, showing that nutrients are vital inplant growth (Silber, 2003). Nitrogen, phosphorus and potassium are the primary macronutrients needed by a plant, and make up large amounts of the plant’s tissues. Nitrogen is an essential part of chlorophyll, while phosphorus is essential to ATP, and potassium is essential to making carbohydrates and proteins. Without these nutrients being available, the plant is not able to achieve maximum potential in producing these elements that are vital to a plant’s life. In addition, a similar experiment, testing the effect of
