Plant Grow Experiment

Minerals are the building blocks of plant growth. Plants need these minerals to make complex molecules. If a plant shows poor growth, it may be due to a lack of or an excess of a mineral(s) in the soil. Efficient and successful plant growth depends on a set of factors: the minerals, the amount of minerals present, the pH of the soil, light quality and quantity, temperature, and the overall rate of photosynthesis. Although there are other factors that affect plant growth, these are the most relevant ones to this experiment.

The reason why I am interested in this is because both my parents came from a farming background, and therefore I have always been taught to value plant life and to care for them. My experiment involves investigating the growth of corn with different Nitrogen concentrations to see which concentration has the greatest effect on the corn plant. …show more content…
Non-mineral nutrients are Hydrogen (H), Oxygen (O), and Carbon (C). They are found in the air and water, and are used in photosynthesis. On the other hand, mineral nutrients are broken down into two groups: Macronutrients and micronutrients. Macronutrients can be broken into two more groups: Primary and Secondary nutrients. Primary nutrients, which are Nitrogen (N), Phosphorus (P), and Potassium (K), are the major, most important nutrients in plant growth, and are usually lacking from the soil because plants use large amounts in order to survive. Secondary nutrients, which include Calcium (Ca), Magnesium (Mg), and Sulfur (S), are found abundantly in the soil. In contrast to macronutrients, micronutrients are essential for plant growth but are only needed in very low quantities. The micronutrients are: Boron (B), Copper (Cu), Iron (Fe), Chloride (Cl), Manganese (Mn), Molybdenum (Mo) and Zinc
